According to the 2021 resus council guidelines, when administering an IV fluid challenge to a child with anaphylaxis, the recommended dose is 10 ml/kg. It is important to note that prior to the update, the advised dose was 20 ml/kg. In an exam, if you are provided with the child’s weight, you may be required to calculate the volume requirement.

Anaphylaxis is a severe and life-threatening allergic reaction that affects the entire body. It is characterized by a rapid onset and can lead to difficulty breathing, low blood pressure, and loss of consciousness. In paediatrics, anaphylaxis is often caused by food allergies, with nuts being the most common trigger. Other causes include drugs and insect venom, such as from a wasp sting.

When treating anaphylaxis, time is of the essence and there may not be enough time to look up medication doses. Adrenaline is the most important drug in managing anaphylaxis and should be administered as soon as possible. The recommended doses of adrenaline vary based on the age of the child. For children under 6 months, the dose is 150 micrograms, while for children between 6 months and 6 years, the dose remains the same. For children between 6 and 12 years, the dose is increased to 300 micrograms, and for adults and children over 12 years, the dose is 500 micrograms. Adrenaline can be repeated every 5 minutes if necessary.

The preferred site for administering adrenaline is the anterolateral aspect of the middle third of the thigh. This ensures quick absorption and effectiveness of the medication. It is important to follow the Resuscitation Council guidelines for anaphylaxis management, as they have recently been updated.

In some cases, it can be challenging to determine if a patient had a true episode of anaphylaxis. In such cases, serum tryptase levels may be measured, as they remain elevated for up to 12 hours following an acute episode of anaphylaxis. This can help confirm the diagnosis and guide further management.

Overall, prompt recognition and administration of adrenaline are crucial in managing anaphylaxis in paediatrics. Following the recommended doses and guidelines can help ensure the best outcomes for patients experiencing this severe allergic reaction.

Acute post-streptococcal glomerulonephritis is a condition that usually occurs at least 2 weeks after a person has had scarlet fever. In this case, the patient’s symptoms are consistent with this condition. It is important to note that the sore throat and rash associated with scarlet fever can be mild and may be mistaken for a generic viral illness with hives. Acute post-streptococcal glomerulonephritis typically presents with blood in the urine (which may appear brown like coca-cola) and protein in the urine. Other symptoms may include decreased urine output, swelling in the extremities, and high blood pressure. It is rare for this condition to cause permanent kidney damage.

Scarlet fever is a reaction to erythrogenic toxins produced by Group A haemolytic streptococci, usually Streptococcus pyogenes. It is more common in children aged 2-6 years, with the peak incidence at 4 years. The typical presentation of scarlet fever includes fever, malaise, sore throat (tonsillitis), and a rash. The rash appears 1-2 days after the fever and sore throat symptoms and consists of fine punctate erythema that first appears on the torso and spares the face. The rash has a rough ‘sandpaper’ texture and desquamation occurs later, particularly around the fingers and toes. Another characteristic feature is the ‘strawberry tongue’, which initially has a white coating and swollen, reddened papillae, and later becomes red and inflamed. Diagnosis is usually made by a throat swab, but antibiotic treatment should be started immediately without waiting for the results. The recommended treatment is oral penicillin V, but patients with a penicillin allergy should be given azithromycin. Children can return to school 24 hours after starting antibiotics. Scarlet fever is a notifiable disease. Complications of scarlet fever include otitis media, rheumatic fever, and acute glomerulonephritis.

The appropriate dose of adrenaline for treating anaphylaxis in children under 6 years old is 150 micrograms, which is equivalent to 0.15 ml of a 1 in 1,000 solution.

Typically, children with viral gastroenteritis experience diarrhoea for a duration of 5-7 days. Vomiting, on the other hand, usually subsides within 1-2 days.

Further Reading:

Gastroenteritis is a common condition in children, particularly those under the age of 5. It is characterized by the sudden onset of diarrhea, with or without vomiting. The most common cause of gastroenteritis in infants and young children is rotavirus, although other viruses, bacteria, and parasites can also be responsible. Prior to the introduction of the rotavirus vaccine in 2013, rotavirus was the leading cause of gastroenteritis in children under 5 in the UK. However, the vaccine has led to a significant decrease in cases, with a drop of over 70% in subsequent years.

Norovirus is the most common cause of gastroenteritis in adults, but it also accounts for a significant number of cases in children. In England & Wales, there are approximately 8,000 cases of norovirus each year, with 15-20% of these cases occurring in children under 9.

When assessing a child with gastroenteritis, it is important to consider whether there may be another more serious underlying cause for their symptoms. Dehydration assessment is also crucial, as some children may require intravenous fluids. The NICE traffic light system can be used to identify the risk of serious illness in children under 5.

In terms of investigations, stool microbiological testing may be indicated in certain cases, such as when the patient has been abroad, if diarrhea lasts for more than 7 days, or if there is uncertainty over the diagnosis. U&Es may be necessary if intravenous fluid therapy is required or if there are symptoms and/or signs suggestive of hypernatremia. Blood cultures may be indicated if sepsis is suspected or if antibiotic therapy is planned.

Fluid management is a key aspect of treating children with gastroenteritis. In children without clinical dehydration, normal oral fluid intake should be encouraged, and oral rehydration solution (ORS) supplements may be considered. For children with dehydration, ORS solution is the preferred method of rehydration, unless intravenous fluid therapy is necessary. Intravenous fluids may be required for children with shock or those who are unable to tolerate ORS solution.

Antibiotics are generally not required for gastroenteritis in children, as most cases are viral or self-limiting. However, there are some exceptions, such as suspected or confirmed sepsis, Extraintestinal spread of bacterial infection, or specific infections like Clostridium difficile-associated pseudomembranous enterocolitis or giardiasis.

The term Apparent Life-Threatening Event (ALTE) has traditionally been used to describe a specific type of event. However, in 2016, the American Academy of Paediatrics (AAP) recommended replacing this term with a new one called Brief Resolved Unexplained Event (BRUE).

An ALTE is defined as an episode that is frightening to the observer and is characterized by a combination of symptoms such as apnoea (central or occasionally obstructive), color change (usually cyanotic or pallid but occasionally erythematous or plethoric), significant change in muscle tone (usually marked limpness), choking, or gagging. In some cases, the observer may even fear that the infant has died.

On the other hand, BRUE has stricter criteria and is only applicable to episodes that occur in infants under 12 months old. A BRUE is considered brief, typically lasting 2-30 seconds but no longer than 1 minute. It must also have resolved, meaning the infant has returned to their baseline state. Additionally, it should not be explained by any identifiable medical condition and must be characterized by at least one of the following: cyanosis or pallor, absent, decreased, or irregular breathing, marked change in muscle tone (hyper- or hypotonia), or altered level of responsiveness.

To diagnose a BRUE, a full history and physical examination of the infant must be conducted, and if no explanation for the event is found, it can be classified as a BRUE. Once a BRUE is diagnosed, it can be risk-stratified to guide further management.

A BRUE is considered low risk if the infant has fully recovered, there are no concerning history or physical examination findings, and the following criteria are met: the infant is over 60 days old, born after 32 weeks gestation with a corrected gestational age over 45 weeks, no CPR was performed by a trained healthcare professional, and this was the first event that lasted less than 1 minute.

Low-risk infants can be safely discharged with early outpatient follow-up within 24 hours. However, it is important to involve the parents/caregivers in the decision-making process. They should be informed that a low-risk BRUE is unlikely to indicate a severe underlying disorder and that the event is unlikely to happen again.

Before discharge, it may be advisable to perform an ECG, observe the infant for a brief period, and conduct a pertussis swab

Patients who have bacterial tracheitis usually do not show any improvement when treated with steroids and adrenaline nebulizers. The symptoms of bacterial tracheitis include a prelude of upper respiratory tract infection symptoms, followed by a rapid decline in health with the presence of stridor and difficulty breathing. Despite treatment with steroids and adrenaline, there is no improvement in the patient’s condition. On the other hand, patients with epiglottitis commonly experience difficulty swallowing and excessive saliva production.

Croup, also known as laryngotracheobronchitis, is a respiratory infection that primarily affects infants and toddlers. It is characterized by a barking cough and can cause stridor (a high-pitched sound during breathing) and respiratory distress due to swelling of the larynx and excessive secretions. The majority of cases are caused by parainfluenza viruses 1 and 3. Croup is most common in children between 6 months and 3 years of age and tends to occur more frequently in the autumn.

The clinical features of croup include a barking cough that is worse at night, preceded by symptoms of an upper respiratory tract infection such as cough, runny nose, and congestion. Stridor, respiratory distress, and fever may also be present. The severity of croup can be graded using the NICE system, which categorizes it as mild, moderate, severe, or impending respiratory failure based on the presence of symptoms such as cough, stridor, sternal/intercostal recession, agitation, lethargy, and decreased level of consciousness. The Westley croup score is another commonly used tool to assess the severity of croup based on the presence of stridor, retractions, air entry, oxygen saturation levels, and level of consciousness.

In cases of severe croup with significant airway obstruction and impending respiratory failure, symptoms may include a minimal barking cough, harder-to-hear stridor, chest wall recession, fatigue, pallor or cyanosis, decreased level of consciousness, and tachycardia. A respiratory rate over 70 breaths per minute is also indicative of severe respiratory distress.

Children with moderate or severe croup, as well as those with certain risk factors such as chronic lung disease, congenital heart disease, neuromuscular disorders, immunodeficiency, age under 3 months, inadequate fluid intake, concerns about care at home, or high fever or a toxic appearance, should be admitted to the hospital. The mainstay of treatment for croup is corticosteroids, which are typically given orally. If the child is too unwell to take oral medication, inhaled budesonide or intramuscular dexamethasone may be used as alternatives. Severe cases may require high-flow oxygen and nebulized adrenaline.

When considering the differential diagnosis for acute stridor and breathing difficulty, non-infective causes such as inhaled foreign bodies

Antihistamines do not help in treating the life-threatening aspects of anaphylaxis and should not be used instead of adrenaline. However, they can be used to relieve symptoms such as skin reactions and itching once the patient’s condition has stabilized. The appropriate dose of cetirizine for children between the ages of 2 and 6 is 2.5-5 mg. It is important to note that chlorpheniramine is no longer recommended. The recommended doses of oral cetirizine for different age groups are as follows: less than 2 years – 250 micrograms/kg, 2-6 years – 2.5-5 mg, 6-11 years – 5-10 mg, 12 years and older – 10-20 mg.

Diabetic ketoacidosis (DKA) is a serious complication of diabetes that occurs due to a lack of insulin in the body. It is most commonly seen in individuals with type 1 diabetes but can also occur in type 2 diabetes. DKA is characterized by hyperglycemia, acidosis, and ketonaemia.

The pathophysiology of DKA involves insulin deficiency, which leads to increased glucose production and decreased glucose uptake by cells. This results in hyperglycemia and osmotic diuresis, leading to dehydration. Insulin deficiency also leads to increased lipolysis and the production of ketone bodies, which are acidic. The body attempts to buffer the pH change through metabolic and respiratory compensation, resulting in metabolic acidosis.

DKA can be precipitated by factors such as infection, physiological stress, non-compliance with insulin therapy, acute medical conditions, and certain medications. The clinical features of DKA include polydipsia, polyuria, signs of dehydration, ketotic breath smell, tachypnea, confusion, headache, nausea, vomiting, lethargy, and abdominal pain.

The diagnosis of DKA is based on the presence of ketonaemia or ketonuria, blood glucose levels above 11 mmol/L or known diabetes mellitus, and a blood pH below 7.3 or bicarbonate levels below 15 mmol/L. Initial investigations include blood gas analysis, urine dipstick for glucose and ketones, blood glucose measurement, and electrolyte levels.

Management of DKA involves fluid replacement, electrolyte correction, insulin therapy, and treatment of any underlying cause. Fluid replacement is typically done with isotonic saline, and potassium may need to be added depending on the patient’s levels. Insulin therapy is initiated with an intravenous infusion, and the rate is adjusted based on blood glucose levels. Monitoring of blood glucose, ketones, bicarbonate, and electrolytes is essential, and the insulin infusion is discontinued once ketones are below 0.3 mmol/L, pH is above 7.3, and bicarbonate is above 18 mmol/L.

Complications of DKA and its treatment include gastric stasis, thromboembolism, electrolyte disturbances, cerebral edema, hypoglycemia, acute respiratory distress syndrome, and acute kidney injury. Prompt medical intervention is crucial in managing DKA to prevent potentially fatal outcomes.

Individuals who have chickenpox should refrain from coming into contact with others for a minimum of 5 days starting from when the rash first appears and continuing until all blisters have formed a crust.

Further Reading:

Chickenpox is caused by the varicella zoster virus (VZV) and is highly infectious. It is spread through droplets in the air, primarily through respiratory routes. It can also be caught from someone with shingles. The infectivity period lasts from 4 days before the rash appears until 5 days after the rash first appeared. The incubation period is typically 10-21 days.

Clinical features of chickenpox include mild symptoms that are self-limiting. However, older children and adults may experience more severe symptoms. The infection usually starts with a fever and is followed by an itchy rash that begins on the head and trunk before spreading. The rash starts as macular, then becomes papular, and finally vesicular. Systemic upset is usually mild.

Management of chickenpox is typically supportive. Measures such as keeping cool and trimming nails can help alleviate symptoms. Calamine lotion can be used to soothe the rash. People with chickenpox should avoid contact with others for at least 5 days from the onset of the rash until all blisters have crusted over. Immunocompromised patients and newborns with peripartum exposure should receive varicella zoster immunoglobulin (VZIG). If chickenpox develops, IV aciclovir should be considered. Aciclovir may be prescribed for immunocompetent, non-pregnant adults or adolescents with severe chickenpox or those at increased risk of complications. However, it is not recommended for otherwise healthy children with uncomplicated chickenpox.

Complications of chickenpox can include secondary bacterial infection of the lesions, pneumonia, encephalitis, disseminated haemorrhagic chickenpox, and rare conditions such as arthritis, nephritis, and pancreatitis.

Shingles is the reactivation of the varicella zoster virus that remains dormant in the nervous system after primary infection with chickenpox. It typically presents with signs of nerve irritation before the eruption of a rash within the dermatomal distribution of the affected nerve. Patients may feel unwell with malaise, myalgia, headache, and fever prior to the rash appearing. The rash appears as erythema with small vesicles that may keep forming for up to 7 days. It usually takes 2-3 weeks for the rash to resolve.

Management of shingles involves keeping the vesicles covered and dry to prevent secondary bacterial infection.

The regular use of sodium bicarbonate in pediatric cardiac arrest is not commonly advised. However, it may be considered in cases of prolonged arrests, and it serves a specific purpose in treating hyperkalemia and the arrhythmias caused by tricyclic antidepressant overdose.

When sodium bicarbonate is administered, the appropriate dosage is 1 ml per kilogram of 8.4% sodium bicarbonate.

The risk of contracting meningococcal disease from a close contact is low. However, the risk is highest within the first seven days after the disease is diagnosed and decreases significantly afterwards.

Prophylaxis or vaccination for close contacts is typically organized by secondary care. It is recommended for the following individuals, regardless of their meningococcal vaccination status:

– People who have had prolonged close contact with the infected person in a household-type setting during the seven days prior to the onset of illness. This includes individuals living or sleeping in the same household, students in the same dormitory, partners, or university students sharing a kitchen in a hall of residence.

– People who have had brief close contact with the infected person, but only if they have been directly exposed to large particle droplets or secretions from the respiratory tract of the case around the time of admission to the hospital.

Antibiotic prophylaxis should be administered as soon as possible, ideally within 24 hours after the diagnosis of the index case.

Post-exposure prophylaxis is recommended for healthcare staff who have been exposed to direct nasopharyngeal secretions (without wearing a mask or personal protective equipment) from a known or highly probable case. This includes situations such as mouth-to-mouth resuscitation, airway management (suction/intubation), or prolonged close care within 1 meter of the patient who has been coughing or sneezing droplet secretions.

For more information, you can refer to the NICE Clinical Knowledge Summary on the management of close contacts of patients with meningococcal disease.

A 7-year-old girl is brought to the emergency department after being bitten by a bee. She is experiencing swelling in her arm and difficulty breathing, which are signs of anaphylaxis. To treat this condition, the most suitable dose of adrenaline to administer to the patient is 300 micrograms (0.3ml 1 in 1,000) by intramuscular injection.

Further Reading:

Anaphylaxis is a severe and life-threatening hypersensitivity reaction that can have sudden onset and progression. It is characterized by skin or mucosal changes and can lead to life-threatening airway, breathing, or circulatory problems. Anaphylaxis can be allergic or non-allergic in nature.

In allergic anaphylaxis, there is an immediate hypersensitivity reaction where an antigen stimulates the production of IgE antibodies. These antibodies bind to mast cells and basophils. Upon re-exposure to the antigen, the IgE-covered cells release histamine and other inflammatory mediators, causing smooth muscle contraction and vasodilation.

Non-allergic anaphylaxis occurs when mast cells degrade due to a non-immune mediator. The clinical outcome is the same as in allergic anaphylaxis.

The management of anaphylaxis is the same regardless of the cause. Adrenaline is the most important drug and should be administered as soon as possible. The recommended doses for adrenaline vary based on age. Other treatments include high flow oxygen and an IV fluid challenge. Corticosteroids and chlorpheniramine are no longer recommended, while non-sedating antihistamines may be considered as third-line treatment after initial stabilization of airway, breathing, and circulation.

Common causes of anaphylaxis include food (such as nuts, which is the most common cause in children), drugs, and venom (such as wasp stings). Sometimes it can be challenging to determine if a patient had a true episode of anaphylaxis. In such cases, serum tryptase levels may be measured, as they remain elevated for up to 12 hours following an acute episode of anaphylaxis.

The Resuscitation Council (UK) provides guidelines for the management of anaphylaxis, including a visual algorithm that outlines the recommended steps for treatment.

In cases of anaphylaxis, it is important to administer non-sedating antihistamines after adrenaline administration and initial resuscitation. Previous guidelines recommended the use of chlorpheniramine and hydrocortisone as third line treatments, but the 2021 guidelines have removed this recommendation. Corticosteroids are no longer advised. Instead, it is now recommended to use non-sedating antihistamines such as cetirizine, loratadine, and fexofenadine, as alternatives to the sedating antihistamine chlorpheniramine. The top priority treatments for anaphylaxis are adrenaline, oxygen, and fluids. The Resuscitation Council advises that administration of non-sedating antihistamines should occur after the initial resuscitation.

Epiglottitis symptoms typically appear suddenly, usually within a day. This patient’s symptoms align with those of epiglottitis and his vaccination status puts him at a higher risk. Common clinical features of epiglottitis include a rapid onset of symptoms, high fever, a sore throat, a change in voice (often described as a muffled or hot potato voice), painful swallowing, a specific positioning called tripod positioning, excessive drooling, and stridor.

Further Reading:

Epiglottitis is a rare but serious condition characterized by inflammation and swelling of the epiglottis, which can lead to a complete blockage of the airway. It is more commonly seen in children between the ages of 2-6, but can also occur in adults, particularly those in their 40s and 50s. Streptococcus infections are now the most common cause of epiglottitis in the UK, although other bacterial agents, viruses, fungi, and iatrogenic causes can also be responsible.

The clinical features of epiglottitis include a rapid onset of symptoms, high fever, sore throat, painful swallowing, muffled voice, stridor and difficulty breathing, drooling of saliva, irritability, and a characteristic tripod positioning with the arms forming the front two legs of the tripod. It is important for healthcare professionals to avoid examining the throat or performing any potentially upsetting procedures until the airway has been assessed and secured.

Diagnosis of epiglottitis is typically made through fibre-optic laryngoscopy, which is considered the gold standard investigation. Lateral neck X-rays may also show a characteristic thumb sign, indicating an enlarged and swollen epiglottis. Throat swabs and blood cultures may be taken once the airway is secured to identify the causative organism.

Management of epiglottitis involves assessing and securing the airway as the top priority. Intravenous or oral antibiotics are typically prescribed, and supplemental oxygen may be given if intubation or tracheostomy is planned. In severe cases where the airway is significantly compromised, intubation or tracheostomy may be necessary. Steroids may also be used, although the evidence for their benefit is limited.

Overall, epiglottitis is a potentially life-threatening condition that requires urgent medical attention. Prompt diagnosis, appropriate management, and securing the airway are crucial in ensuring a positive outcome for patients with this condition.

SSPE, also known as subacute sclerosing panencephalitis, is a serious and potentially deadly complication that can occur as a result of measles. While pneumonia and otitis media are commonly seen complications of measles, SSPE is much rarer. This condition involves inflammation of the brain and is believed to occur either due to the reactivation of the measles virus or an abnormal immune response to the virus.

Further Reading:

Measles is a highly contagious viral infection caused by an RNA paramyxovirus. It is primarily spread through aerosol transmission, specifically through droplets in the air. The incubation period for measles is typically 10-14 days, during which patients are infectious from 4 days before the appearance of the rash to 4 days after.

Common complications of measles include pneumonia, otitis media (middle ear infection), and encephalopathy (brain inflammation). However, a rare but fatal complication called subacute sclerosing panencephalitis (SSPE) can also occur, typically presenting 5-10 years after the initial illness.

The onset of measles is characterized by a prodrome, which includes symptoms such as irritability, malaise, conjunctivitis, and fever. Before the appearance of the rash, white spots known as Koplik spots can be seen on the buccal mucosa. The rash itself starts behind the ears and then spreads to the entire body, presenting as a discrete maculopapular rash that becomes blotchy and confluent.

In terms of complications, encephalitis typically occurs 1-2 weeks after the onset of the illness. Febrile convulsions, giant cell pneumonia, keratoconjunctivitis, corneal ulceration, diarrhea, increased incidence of appendicitis, and myocarditis are also possible complications of measles.

When managing contacts of individuals with measles, it is important to offer the MMR vaccine to children who have not been immunized against measles. The vaccine-induced measles antibody develops more rapidly than that following natural infection, so it should be administered within 72 hours of contact.

Pyloric stenosis, a condition characterized by narrowing of the pylorus (the opening between the stomach and small intestine), often leads to an electrolyte imbalance. This imbalance typically presents as hypochloremia (low chloride levels), hypokalemia (low potassium levels), and metabolic alkalosis (an increase in blood pH). To confirm the diagnosis, it is recommended to perform U&Es (tests to measure electrolyte levels) and a venous blood gas analysis. The electrolyte abnormalities observed in pyloric stenosis are primarily caused by the loss of hydrogen and chloride ions through vomiting. While urine is usually alkaline in this condition, severe dehydration can lead to paradoxical aciduria, where hydrogen ions are preferentially secreted instead of potassium ions to prevent further decrease in potassium levels.

Further Reading:

Pyloric stenosis is a condition that primarily affects infants, characterized by the thickening of the muscles in the pylorus, leading to obstruction of the gastric outlet. It typically presents between the 3rd and 12th weeks of life, with recurrent projectile vomiting being the main symptom. The condition is more common in males, with a positive family history and being first-born being additional risk factors. Bottle-fed children and those delivered by c-section are also more likely to develop pyloric stenosis.

Clinical features of pyloric stenosis include projectile vomiting, usually occurring about 30 minutes after a feed, as well as constipation and dehydration. A palpable mass in the upper abdomen, often described as like an olive, may also be present. The persistent vomiting can lead to electrolyte disturbances, such as hypochloremia, alkalosis, and mild hypokalemia.

Ultrasound is the preferred diagnostic tool for confirming pyloric stenosis. It can reveal specific criteria, including a pyloric muscle thickness greater than 3 mm, a pylorus longitudinal length greater than 15-17 mm, a pyloric volume greater than 1.5 cm3, and a pyloric transverse diameter greater than 13 mm.

The definitive treatment for pyloric stenosis is pyloromyotomy, a surgical procedure that involves making an incision in the thickened pyloric muscle to relieve the obstruction. Before surgery, it is important to correct any hypovolemia and electrolyte disturbances with intravenous fluids. Overall, pyloric stenosis is a relatively common condition in infants, but with prompt diagnosis and appropriate management, it can be effectively treated.

Anaphylaxis caused by a lack of C1 esterase inhibitor is not effectively treated with adrenaline, steroids, or antihistamines. Instead, treatment requires the use of C1 esterase inhibitor concentrate or fresh frozen plasma.

Anaphylaxis is a severe and life-threatening allergic reaction that affects the entire body. It is characterized by a rapid onset and can lead to difficulty breathing, low blood pressure, and loss of consciousness. In paediatrics, anaphylaxis is often caused by food allergies, with nuts being the most common trigger. Other causes include drugs and insect venom, such as from a wasp sting.

When treating anaphylaxis, time is of the essence and there may not be enough time to look up medication doses. Adrenaline is the most important drug in managing anaphylaxis and should be administered as soon as possible. The recommended doses of adrenaline vary based on the age of the child. For children under 6 months, the dose is 150 micrograms, while for children between 6 months and 6 years, the dose remains the same. For children between 6 and 12 years, the dose is increased to 300 micrograms, and for adults and children over 12 years, the dose is 500 micrograms. Adrenaline can be repeated every 5 minutes if necessary.

The preferred site for administering adrenaline is the anterolateral aspect of the middle third of the thigh. This ensures quick absorption and effectiveness of the medication. It is important to follow the Resuscitation Council guidelines for anaphylaxis management, as they have recently been updated.

In some cases, it can be challenging to determine if a patient had a true episode of anaphylaxis. In such cases, serum tryptase levels may be measured, as they remain elevated for up to 12 hours following an acute episode of anaphylaxis. This can help confirm the diagnosis and guide further management.

Overall, prompt recognition and administration of adrenaline are crucial in managing anaphylaxis in paediatrics. Following the recommended doses and guidelines can help ensure the best outcomes for patients experiencing this severe allergic reaction.

The most suitable approach for investigation in this case would be to send a blood test for Epstein-Barr virus (EBV) viral serology. Glandular fever, also known as infectious mononucleosis, is commonly caused by the Epstein-Barr virus. The symptoms described by the patient, including a sore throat, fever, and feeling unwell, are consistent with this condition. To confirm the diagnosis, a blood test for EBV viral serology can be performed. This test detects antibodies produced by the body in response to the virus. It is important to note that the Monospot test, which is another blood test for infectious mononucleosis, may not be as accurate in younger children. Therefore, the most appropriate option would be to send a blood test for EBV viral serology in 2-3 days time. This will allow for the detection of specific antibodies and provide a more accurate diagnosis.

Glandular fever, also known as infectious mononucleosis or mono, is a clinical syndrome characterized by symptoms such as sore throat, fever, and swollen lymph nodes. It is primarily caused by the Epstein-Barr virus (EBV), with other viruses and infections accounting for the remaining cases. Glandular fever is transmitted through infected saliva and primarily affects adolescents and young adults. The incubation period is 4-8 weeks.

The majority of EBV infections are asymptomatic, with over 95% of adults worldwide having evidence of prior infection. Clinical features of glandular fever include fever, sore throat, exudative tonsillitis, lymphadenopathy, and prodromal symptoms such as fatigue and headache. Splenomegaly (enlarged spleen) and hepatomegaly (enlarged liver) may also be present, and a non-pruritic macular rash can sometimes occur.

Glandular fever can lead to complications such as splenic rupture, which increases the risk of rupture in the spleen. Approximately 50% of splenic ruptures associated with glandular fever are spontaneous, while the other 50% follow trauma. Diagnosis of glandular fever involves various investigations, including viral serology for EBV, monospot test, and liver function tests. Additional serology tests may be conducted if EBV testing is negative.

Management of glandular fever involves supportive care and symptomatic relief with simple analgesia. Antiviral medication has not been shown to be beneficial. It is important to identify patients at risk of serious complications, such as airway obstruction, splenic rupture, and dehydration, and provide appropriate management. Patients can be advised to return to normal activities as soon as possible, avoiding heavy lifting and contact sports for the first month to reduce the risk of splenic rupture.

Rare but serious complications associated with glandular fever include hepatitis, upper airway obstruction, cardiac complications, renal complications, neurological complications, haematological complications, chronic fatigue, and an increased risk of lymphoproliferative cancers and multiple sclerosis.

Children with severe croup require high flow oxygen and nebulized adrenaline as part of their treatment. If a child is agitated or lethargic, it is a sign that the disease is severe. In addition to standard steroid treatment, high flow oxygen and nebulized adrenaline are necessary for treating severe croup. It is important to note that beta 2 agonists are not effective for children under 2 years old.

Croup, also known as laryngotracheobronchitis, is a respiratory infection that primarily affects infants and toddlers. It is characterized by a barking cough and can cause stridor (a high-pitched sound during breathing) and respiratory distress due to swelling of the larynx and excessive secretions. The majority of cases are caused by parainfluenza viruses 1 and 3. Croup is most common in children between 6 months and 3 years of age and tends to occur more frequently in the autumn.

The clinical features of croup include a barking cough that is worse at night, preceded by symptoms of an upper respiratory tract infection such as cough, runny nose, and congestion. Stridor, respiratory distress, and fever may also be present. The severity of croup can be graded using the NICE system, which categorizes it as mild, moderate, severe, or impending respiratory failure based on the presence of symptoms such as cough, stridor, sternal/intercostal recession, agitation, lethargy, and decreased level of consciousness. The Westley croup score is another commonly used tool to assess the severity of croup based on the presence of stridor, retractions, air entry, oxygen saturation levels, and level of consciousness.

In cases of severe croup with significant airway obstruction and impending respiratory failure, symptoms may include a minimal barking cough, harder-to-hear stridor, chest wall recession, fatigue, pallor or cyanosis, decreased level of consciousness, and tachycardia. A respiratory rate over 70 breaths per minute is also indicative of severe respiratory distress.

Children with moderate or severe croup, as well as those with certain risk factors such as chronic lung disease, congenital heart disease, neuromuscular disorders, immunodeficiency, age under 3 months, inadequate fluid intake, concerns about care at home, or high fever or a toxic appearance, should be admitted to the hospital. The mainstay of treatment for croup is corticosteroids, which are typically given orally. If the child is too unwell to take oral medication, inhaled budesonide or intramuscular dexamethasone may be used as alternatives. Severe cases may require high-flow oxygen and nebulized adrenaline.

When considering the differential diagnosis for acute stridor and breathing difficulty, non-infective causes such as inhaled foreign bodies

In pediatric patients who have sustained burns in a house fire, the presence of burns greater than 15% of the total body surface area should trigger the initiation of immediate fluid resuscitation.

Further Reading:

Burn injuries can be classified based on their type (degree, partial thickness or full thickness), extent as a percentage of total body surface area (TBSA), and severity (minor, moderate, major/severe). Severe burns are defined as a >10% TBSA in a child and >15% TBSA in an adult.

When assessing a burn, it is important to consider airway injury, carbon monoxide poisoning, type of burn, extent of burn, special considerations, and fluid status. Special considerations may include head and neck burns, circumferential burns, thorax burns, electrical burns, hand burns, and burns to the genitalia.

Airway management is a priority in burn injuries. Inhalation of hot particles can cause damage to the respiratory epithelium and lead to airway compromise. Signs of inhalation injury include visible burns or erythema to the face, soot around the nostrils and mouth, burnt/singed nasal hairs, hoarse voice, wheeze or stridor, swollen tissues in the mouth or nostrils, and tachypnea and tachycardia. Supplemental oxygen should be provided, and endotracheal intubation may be necessary if there is airway obstruction or impending obstruction.

The initial management of a patient with burn injuries involves conserving body heat, covering burns with clean or sterile coverings, establishing IV access, providing pain relief, initiating fluid resuscitation, measuring urinary output with a catheter, maintaining nil by mouth status, closely monitoring vital signs and urine output, monitoring the airway, preparing for surgery if necessary, and administering medications.

Burns can be classified based on the depth of injury, ranging from simple erythema to full thickness burns that penetrate into subcutaneous tissue. The extent of a burn can be estimated using methods such as the rule of nines or the Lund and Browder chart, which takes into account age-specific body proportions.

Fluid management is crucial in burn injuries due to significant fluid losses. Evaporative fluid loss from burnt skin and increased permeability of blood vessels can lead to reduced intravascular volume and tissue perfusion. Fluid resuscitation should be aggressive in severe burns, while burns <15% in adults and <10% in children may not require immediate fluid resuscitation. The Parkland formula can be used to calculate the intravenous fluid requirements for someone with a significant burn injury.

Patients experiencing an anaphylactic reaction should be observed for a minimum of 6 hours. However, according to the Royal College of Emergency Medicine (RCEM), certain situations require a 24-hour observation period. These situations include patients with a history of biphasic reactions or known asthma, cases where there is a possibility of ongoing absorption of the allergen, limited access to emergency care, presentation during the evening or night, and severe reactions with a slow onset caused by idiopathic anaphylaxis. It is important to note that the National Institute for Health and Care Excellence (NICE) recommends that patients under the age of 16 be admitted under the care of a pediatrician for observation.

Anaphylaxis is a severe and life-threatening allergic reaction that affects the entire body. It is characterized by a rapid onset and can lead to difficulty breathing, low blood pressure, and loss of consciousness. In paediatrics, anaphylaxis is often caused by food allergies, with nuts being the most common trigger. Other causes include drugs and insect venom, such as from a wasp sting.

When treating anaphylaxis, time is of the essence and there may not be enough time to look up medication doses. Adrenaline is the most important drug in managing anaphylaxis and should be administered as soon as possible. The recommended doses of adrenaline vary based on the age of the child. For children under 6 months, the dose is 150 micrograms, while for children between 6 months and 6 years, the dose remains the same. For children between 6 and 12 years, the dose is increased to 300 micrograms, and for adults and children over 12 years, the dose is 500 micrograms.

The most effective treatment for pyloric stenosis is pyloromyotomy, a surgical procedure. Before undergoing surgery, the patient should be rehydrated and any electrolyte imbalances should be corrected.

Further Reading:

Pyloric stenosis is a condition that primarily affects infants, characterized by the thickening of the muscles in the pylorus, leading to obstruction of the gastric outlet. It typically presents between the 3rd and 12th weeks of life, with recurrent projectile vomiting being the main symptom. The condition is more common in males, with a positive family history and being first-born being additional risk factors. Bottle-fed children and those delivered by c-section are also more likely to develop pyloric stenosis.

Clinical features of pyloric stenosis include projectile vomiting, usually occurring about 30 minutes after a feed, as well as constipation and dehydration. A palpable mass in the upper abdomen, often described as like an olive, may also be present. The persistent vomiting can lead to electrolyte disturbances, such as hypochloremia, alkalosis, and mild hypokalemia.

Ultrasound is the preferred diagnostic tool for confirming pyloric stenosis. It can reveal specific criteria, including a pyloric muscle thickness greater than 3 mm, a pylorus longitudinal length greater than 15-17 mm, a pyloric volume greater than 1.5 cm3, and a pyloric transverse diameter greater than 13 mm.

The definitive treatment for pyloric stenosis is pyloromyotomy, a surgical procedure that involves making an incision in the thickened pyloric muscle to relieve the obstruction. Before surgery, it is important to correct any hypovolemia and electrolyte disturbances with intravenous fluids. Overall, pyloric stenosis is a relatively common condition in infants, but with prompt diagnosis and appropriate management, it can be effectively treated.

The most appropriate next step in managing this patient is to rapidly infuse 10 ml/kg of 0.9% sodium chloride solution intravenously. This is because the girl is showing signs of severe dehydration, such as lethargy, decreased urine output, mottled skin, and prolonged capillary refill time. Rapid intravenous fluid administration is necessary to quickly restore her fluid volume and prevent further complications.

Gastroenteritis is a common condition in children, particularly those under the age of 5. It is characterized by the sudden onset of diarrhea, with or without vomiting. The most common cause of gastroenteritis in infants and young children is rotavirus, although other viruses, bacteria, and parasites can also be responsible. Prior to the introduction of the rotavirus vaccine in 2013, rotavirus was the leading cause of gastroenteritis in children under 5 in the UK. However, the vaccine has led to a significant decrease in cases, with a drop of over 70% in subsequent years.

Norovirus is the most common cause of gastroenteritis in adults, but it also accounts for a significant number of cases in children. In England & Wales, there are approximately 8,000 cases of norovirus each year, with 15-20% of these cases occurring in children under 9.

When assessing a child with gastroenteritis, it is important to consider whether there may be another more serious underlying cause for their symptoms. Dehydration assessment is also crucial, as some children may require intravenous fluids. The NICE traffic light system can be used to identify the risk of serious illness in children under 5.

In terms of investigations, stool microbiological testing may be indicated in certain cases, such as when the patient has been abroad, if diarrhea lasts for more than 7 days, or if there is uncertainty over the diagnosis. U&Es may be necessary if intravenous fluid therapy is required or if there are symptoms and/or signs suggestive of hypernatremia. Blood cultures may be indicated if sepsis is suspected or if antibiotic therapy is planned.

Fluid management is a key aspect of treating children with gastroenteritis. In children without clinical dehydration, normal oral fluid intake should be encouraged, and oral rehydration solution (ORS) supplements may be considered. For children with dehydration, ORS solution is the preferred method of rehydration, unless intravenous fluid therapy is necessary. Intravenous fluids may be required for children with shock or those who are unable to tolerate ORS solution.

Antibiotics are generally not required for gastroenteritis in children, as most cases are viral or self-limiting. However, there are some exceptions, such as suspected or confirmed sepsis, Extraintestinal spread of bacterial infection, or specific infections like Clostridium difficile-associated pseudomembranous enterocolitis or giardiasis.

Ketamine should not be used in individuals who have pulmonary hypertension, as it can worsen their condition. Additionally, it is contraindicated in children under 12 months old, as they are at a higher risk of experiencing laryngospasm and airway complications. Other contraindications include a high risk of laryngospasm (such as having an active respiratory infection or asthma), unstable or abnormal airway (due to tracheal surgery or stenosis), active upper or lower respiratory tract infection, proposed procedure within the mouth or pharynx, severe psychological problems, significant cardiac disease, intracranial hypertension with cerebrospinal fluid obstruction, intraocular pathology, previous psychotic illness, uncontrolled epilepsy, hyperthyroidism or taking thyroid medication, porphyria, prior adverse reaction to ketamine, altered conscious level due to acute illness or injury, and drug or alcohol intoxication.

Ketamine sedation in children should only be performed by a trained and competent clinician who is capable of managing complications, especially those related to the airway. The clinician should have completed the necessary training and have the appropriate skills for procedural sedation. It is important for the clinician to consider the length of the procedure before deciding to use ketamine sedation, as lengthy procedures may be more suitable for general anesthesia.

Examples of procedures where ketamine may be used in children include suturing, fracture reduction/manipulation, joint reduction, burn management, incision and drainage of abscess, tube thoracostomy placement, foreign body removal, and wound exploration/irrigation.

During the ketamine sedation procedure, a minimum of three staff members should be present: a doctor to manage the sedation and airway, a clinician to perform the procedure, and an experienced nurse to monitor and support the patient, family, and clinical staff. The child should be sedated and managed in a high dependency or resuscitation area with immediate access to resuscitation facilities. Monitoring should include sedation level, pain, ECG, blood pressure, respiration, pulse oximetry, and capnography, with observations taken and recorded every 5 minutes.

Prior to the procedure, consent should be obtained from the parent or guardian after discussing the proposed procedure and use of ketamine sedation. The risks and potential complications should be explained, including mild or moderate/severe agitation, rash, vomiting, transient clonic movements, and airway problems. The parent should also be informed that certain common side effects, such as nystagmus, random purposeless movements, muscle twitching, rash, and vocalizations, are of no clinical significance.

Topical anesthesia may be considered to reduce the pain of intravenous cannulation, but this step may not be advisable if the procedure is urgent. The clinician should also ensure that key resuscitation drugs are readily available and doses are calculated for the patient in case they are needed.

Before administering ketamine, the child should be prepared by encouraging the parents or guardians to talk to them about happy thoughts and topics to minimize unpleasant emergence phenomena. The dose of ketamine is typically 1.0 mg/kg by slow intravenous injection over at least one minute, with additional doses of 0.5 mg/kg administered as required after 5-10 minutes to achieve the desired dissociative state.

Acute epiglottitis is a condition characterized by inflammation of the epiglottis. It can be life-threatening as it can completely block the airway, especially if not diagnosed promptly. In the past, the most common cause was Haemophilus influenzae type b (Hib), but with the widespread use of the Hib vaccine, it has become rare in children and is now more commonly seen in adults caused by Streptococcus spp like Streptococcus pyogenes and Streptococcus pneumonia. Other bacterial causes include Staphylococcus aureus, Pseudomonas spp, Moraxella catarrhalis, and Mycobacterium tuberculosis.

The typical symptoms of acute epiglottitis include fever, sore throat (initially resembling a viral sore throat), painful swallowing, difficulty swallowing secretions (seen as drooling in children), muffled voice (referred to as ‘hot potato’ voice), rapid heartbeat, tenderness in the front of the neck over the hyoid bone, cervical lymph node enlargement, and rapid deterioration in children.

To diagnose acute epiglottitis, the gold standard investigation is fibre-optic laryngoscopy, which allows direct visualization of the epiglottis. However, laryngoscopy should only be performed in settings prepared for intubation or tracheostomy in case upper airway obstruction occurs. If laryngoscopy is not possible, a lateral neck X-ray may be helpful, as it can show the characteristic ‘thumbprint sign’.

Management of acute epiglottitis usually involves conservative measures such as intravenous or oral antibiotics. However, in some cases, intubation may be necessary.

The age of the child can help determine the most probable diagnosis. Transient synovitis (irritable hip) is commonly observed in children aged 3 to 10. Septic arthritis is more prevalent in children under 4 years old, while Perthes disease is typically diagnosed between the ages of 4 and 8. SUFE is usually seen in girls around the age of 12 and boys around the age of 13.

Further Reading:

– Transient Synovitis (irritable hip):
– Most common hip problem in children
– Causes transient inflammation of the synovium
– Presents with thigh, groin, and/or hip pain with impaired weight bearing
– Mild to moderate restriction of hip internal rotation is common
– Symptoms usually resolve quickly with rest and anti-inflammatory treatment

– Slipped Upper Femoral Epiphysis (SUFE):
– Displacement of the femoral head epiphysis postero-inferiorly
– Usually affects adolescents
– Can present acutely following trauma or with chronic, persistent symptoms
– Associated with loss of internal rotation of the leg in flexion
– Treatment involves surgical fixation by pinning

– Perthes disease:
– Degenerative condition affecting the hip joints of children
– Avascular necrosis of the femoral head is the cause
– Presents with hip pain, limp, stiffness, and reduced range of hip movements
– X-ray changes include widening of joint space and decreased femoral head size/flattening
– Treatment can be conservative or operative, depending on the severity

– Important differentials:
– Septic arthritis: Acute hip pain associated with systemic upset and severe limitation of affected joint
– Non-accidental injury (NAI): Should be considered in younger children and toddlers presenting with a limp, even without a trauma history
– Malignancy: Rare, but osteosarcoma may present with hip pain or limp, especially in tall teenage boys
– Developmental dysplasia of the hip: Often picked up on newborn examination with positive Barlow and Ortolani tests
– Juvenile idiopathic arthritis (JIA): Joint pain and swelling, limp, positive ANA in some cases
– Coagulopathy: Haemophilia, HSP, and sickle cell disease can cause hip pain through different mechanisms

When children with diabetic ketoacidosis (DKA) show signs of shock such as low blood pressure, fast heart rate, and poor peripheral perfusion, it is important for clinicians to consider DKA as a possible cause. In these cases, the initial treatment should involve giving a fluid bolus of 10 ml/kg to help stabilize the patient.

Further Reading:

Diabetic ketoacidosis (DKA) is a serious complication of diabetes that occurs due to a lack of insulin in the body. It is most commonly seen in individuals with type 1 diabetes but can also occur in type 2 diabetes. DKA is characterized by hyperglycemia, acidosis, and ketonaemia.

The pathophysiology of DKA involves insulin deficiency, which leads to increased glucose production and decreased glucose uptake by cells. This results in hyperglycemia and osmotic diuresis, leading to dehydration. Insulin deficiency also leads to increased lipolysis and the production of ketone bodies, which are acidic. The body attempts to buffer the pH change through metabolic and respiratory compensation, resulting in metabolic acidosis.

DKA can be precipitated by factors such as infection, physiological stress, non-compliance with insulin therapy, acute medical conditions, and certain medications. The clinical features of DKA include polydipsia, polyuria, signs of dehydration, ketotic breath smell, tachypnea, confusion, headache, nausea, vomiting, lethargy, and abdominal pain.

The diagnosis of DKA is based on the presence of ketonaemia or ketonuria, blood glucose levels above 11 mmol/L or known diabetes mellitus, and a blood pH below 7.3 or bicarbonate levels below 15 mmol/L. Initial investigations include blood gas analysis, urine dipstick for glucose and ketones, blood glucose measurement, and electrolyte levels.

Management of DKA involves fluid replacement, electrolyte correction, insulin therapy, and treatment of any underlying cause. Fluid replacement is typically done with isotonic saline, and potassium may need to be added depending on the patient’s levels. Insulin therapy is initiated with an intravenous infusion, and the rate is adjusted based on blood glucose levels. Monitoring of blood glucose, ketones, bicarbonate, and electrolytes is essential, and the insulin infusion is discontinued once ketones are below 0.3 mmol/L, pH is above 7.3, and bicarbonate is above 18 mmol/L.

Complications of DKA and its treatment include gastric stasis, thromboembolism, electrolyte disturbances, cerebral edema, hypoglycemia, acute respiratory distress syndrome, and acute kidney injury. Prompt medical intervention is crucial in managing DKA to prevent potentially fatal outcomes.

The recommended first line analgesics for mild pain are oral or rectal paracetamol and oral ibuprofen. When it comes to treating mild pain in children, it is best to consider either giving a loading dose of oral/rectal paracetamol at a rate of 20 mg/kg, followed by a maintenance dose of 15 mg/kg every 4-6 hours. Alternatively, oral ibuprofen can be administered at a rate of 10 mg/kg every 6-8 hours.

Further Reading:

Assessment and alleviation of pain should be a priority when treating ill and injured children, according to the RCEM QEC standards. These standards state that all children attending the Emergency Department should receive analgesia for moderate and severe pain within 20 minutes of arrival. The effectiveness of the analgesia should be re-evaluated within 60 minutes of receiving the first dose. Additionally, patients in moderate pain should be offered oral analgesia at triage or assessment.

Pain assessment in children should take into account their age. Visual analogue pain scales are commonly used, and the RCEM has developed its own version of this. Other indicators of pain, such as crying, limping, and holding or not-moving limbs, should also be observed and utilized in the pain assessment.

Managing pain in children involves a combination of psychological strategies, non-pharmacological adjuncts, and pharmacological methods. Psychological strategies include involving parents, providing cuddles, and utilizing child-friendly environments with toys. Explanation and reassurance are also important in building trust. Distraction with stories, toys, and activities can help divert the child’s attention from the pain.

Non-pharmacological adjuncts for pain relief in children include limb immobilization with slings, plasters, or splints, as well as dressings and other treatments such as reduction of dislocation or trephine subungual hematoma.

Pharmacological methods for pain relief in children include the use of anesthetics, analgesics, and sedation. Topical anesthetics, such as lidocaine with prilocaine cream, tetracaine gel, or ethyl chloride spray, should be considered for children who are likely to require venesection or placement of an intravenous cannula.

Procedural sedation in children often utilizes either ketamine or midazolam. When administering analgesia, the analgesic ladder should be followed as recommended by the RCEM.

Overall, effective pain management in children requires a comprehensive approach that addresses both the physical and psychological aspects of pain. By prioritizing pain assessment and providing appropriate pain relief, healthcare professionals can help alleviate the suffering of ill and injured children.
