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.

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.

The diagnostic criteria for hypertrophic pyloric stenosis (HPS) on ultrasound are as follows: the thickness of the pyloric muscle should be greater than 3 mm, the longitudinal length of the pylorus should be greater than 15-17 mm, the volume of the pylorus should be greater than 1.5 cm3, and the transverse diameter of the pylorus should be greater than 13 mm.

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.

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

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 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 ALTE with a new term 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 characterized by being brief (lasting less than 1 minute, typically 2-30 seconds), resolved (the infant must have returned to their baseline state), and not explained by any identifiable medical condition. It must also exhibit at least one of the following symptoms: 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 thorough history and physical examination of the infant must be conducted, and no explanation for the event should be found. Additionally, there are several risk factors associated with the development of a BRUE, including prematurity, age less than ten weeks, recent anesthesia, airway or maxillofacial abnormalities, history of gastro-oesophageal reflux disease, previous apnoeic episode, recent upper respiratory tract infection. Low birth weight may also be a risk factor, while high birth weight has no recognized association with BRUEs.

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.

Fluid deficit in children and young people with severe diabetic ketoacidosis (DKA) is determined by measuring their blood pH and bicarbonate levels. If the blood pH is below 7.1 and/or the bicarbonate level is below 5, it indicates a fluid deficit. This simplified explanation uses a cutoff value of 5 to determine the severity of the fluid deficit in DKA.

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.

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. 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.

Croup is identified by a distinct cough that sounds like a seal barking. This type of cough is commonly seen in patients within the typical age range for croup. Along with the barking cough, the patient may also experience hoarseness, stridor (a high-pitched sound during breathing), and respiratory distress. While there may be a history of a foreign body in the upper airway, it is not always present. The symptoms of an upper respiratory tract infection prior to the onset of croup do not align with a foreign body diagnosis. Additionally, there is no mention of a rash, which would be indicative of measles.
