Patients who have suffered burns should receive high-flow oxygen (15 L) through a reservoir bag while their breathing is being evaluated. If intubation is necessary, it is crucial to use an appropriately sized endotracheal tube (ETT). Using a tube that is too small can make it difficult or even impossible to ventilate the patient, clear secretions, or perform bronchoscopy.

According to the ATLS guidelines, adults should be intubated using an ETT with an internal diameter (ID) of at least 7.5 mm or larger. Children, on the other hand, should have an ETT with an ID of at least 4.5 mm. Once a patient has been intubated, it is important to continue administering 100% oxygen until their carboxyhemoglobin levels drop to less than 5%.

To protect the lungs, it is recommended to use lung protective ventilation techniques. This involves using low tidal volumes (4-8 mL/kg) and ensuring that peak inspiratory pressures do not exceed 30 cmH2O.

Compartment syndrome can occur when there are circumferential burns on the arms or legs. This typically happens with full thickness burns, where the burnt skin becomes stiff and compresses the compartment, making it difficult for blood to flow out. To treat this condition, escharotomy and possibly fasciotomy may be necessary.

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.

Lipohaemathrosis is commonly seen in the suprapatellar pouch in individuals who have tibial plateau fractures. Notable X-ray characteristics of tibial plateau fractures include a visible fracture of the tibial plateau and the presence of lipohaemathrosis in the suprapatellar pouch.

Further Reading:

Tibial plateau fractures are a type of traumatic lower limb and joint injury that can involve the medial or lateral tibial plateau, or both. These fractures are classified using the Schatzker classification, with higher grades indicating a worse prognosis. X-ray imaging can show visible fractures of the tibial plateau and the presence of lipohaemathrosis in the suprapatellar pouch. However, X-rays often underestimate the severity of these fractures, so CT scans are typically used for a more accurate assessment.

Tibial spine fractures, on the other hand, are separate from tibial plateau fractures. They occur when the tibial spine is avulsed by the anterior cruciate ligament (ACL). This can happen due to forced knee hyperextension or a direct blow to the femur when the knee is flexed. These fractures are most common in children aged 8-14.

Tibial tuberosity avulsion fractures primarily affect adolescent boys and are often caused by jumping or landing from a jump. These fractures can be associated with Osgood-Schlatter disease. The treatment for these fractures depends on their grading. Low-grade fractures may be managed with immobilization for 4-6 weeks, while more significant avulsions are best treated with surgical fixation.

Recognizing the extent of blood loss based on vital sign and mental status abnormalities is a crucial skill. The Advanced Trauma Life Support (ATLS) classification for hemorrhagic shock correlates the amount of blood loss with expected physiological responses in a healthy individual weighing 70 kg. In terms of body weight, the total circulating blood volume accounts for approximately 7%, which is roughly equivalent to five liters in an average 70 kg male patient.

The ATLS classification for hemorrhagic shock is as follows:

CLASS I:
– Blood loss: Up to 750 mL
– Blood loss (% blood volume): Up to 15%
– Pulse rate: Less than 100 beats per minute (bpm)
– Systolic blood pressure: Normal
– Pulse pressure: Normal (or increased)
– Respiratory rate: 14-20 breaths per minute
– Urine output: Greater than 30 mL/hr
– CNS/mental status: Slightly anxious

CLASS II:
– Blood loss: 750-1500 mL
– Blood loss (% blood volume): 15-30%
– Pulse rate: 100-120 bpm
– Systolic blood pressure: Normal
– Pulse pressure: Decreased
– Respiratory rate: 20-30 breaths per minute
– Urine output: 20-30 mL/hr
– CNS/mental status: Mildly anxious

CLASS III:
– Blood loss: 1500-2000 mL
– Blood loss (% blood volume): 30-40%
– Pulse rate: 120-140 bpm
– Systolic blood pressure: Decreased
– Pulse pressure: Decreased
– Respiratory rate: 30-40 breaths per minute
– Urine output: 5-15 mL/hr
– CNS/mental status: Anxious, confused

CLASS IV:
– Blood loss: More than 2000 mL
– Blood loss (% blood volume): More than 40%
– Pulse rate: More than 140 bpm
– Systolic blood pressure: Decreased
– Pulse pressure: Decreased
– Respiratory rate: More than 40 breaths per minute
– Urine output: Negligible
– CNS/mental status: Confused, lethargic

Intraosseous access is recommended in trauma, burns, or resuscitation situations when other attempts at venous access fail or would take longer than one minute. It is particularly recommended for circulatory access in pediatric cardiac arrest cases. This technique can also be used when urgent blood sampling or intravenous access is needed and traditional cannulation is difficult and time-consuming. It serves as a temporary measure to stabilize the patient and facilitate long-term intravenous access.

Potential complications of intraosseous access include compartment syndrome, infection, and fracture. Therefore, it is contraindicated to use this method on the side of definitively fractured bones or limbs with possible proximal fractures. It should also not be used at sites of previous attempts or in patients with conditions such as osteogenesis imperfecta or osteopetrosis.

There are several possible sites for intraosseous access insertion. These include the proximal humerus, approximately 1 cm above the surgical neck; the proximal tibia, on the anterior surface, 2-3 cm below the tibial tuberosity; the distal tibia, 3 cm proximal to the most prominent aspect of the medial malleolus; the femoral region, on the anterolateral surface, 3 cm above the lateral condyle; the iliac crest; and the sternum.

Early assessment of the airway is a critical aspect of managing a burned patient. Airway obstruction can occur rapidly due to direct injury or swelling from the burn. If there is a history of trauma, the airway should be evaluated while maintaining cervical spine control.

There are several risk factors for airway obstruction in burned patients, including inhalation injury, soot in the mouth or nostrils, singed nasal hairs, burns to the head, face, and neck, burns inside the mouth, large burn area and increasing burn depth, associated trauma, and a carboxyhemoglobin level above 10%.

In cases where significant swelling is anticipated, it may be necessary to urgently secure the airway with an uncut endotracheal tube before the swelling becomes severe. Delaying recognition of impending airway obstruction can make intubation difficult, and a surgical airway may be required.

The American Burn Life Support (ABLS) guidelines recommend early intubation in certain situations. These include signs of airway obstruction, extensive burns, deep facial burns, burns inside the mouth, significant swelling or risk of swelling, difficulty swallowing, respiratory compromise, decreased level of consciousness, and anticipated transfer of a patient with a large burn and airway issues without qualified personnel to intubate during transport.

Circumferential burns of the neck can cause tissue swelling around the airway, making early intubation necessary in these cases as well.

The main objectives in managing haemothorax are to restore the lost blood volume and relieve pressure in the pleural space. These actions are crucial for improving the patient’s oxygen levels.

Further Reading:

Haemothorax is the accumulation of blood in the pleural cavity of the chest, usually resulting from chest trauma. It can be difficult to differentiate from other causes of pleural effusion on a chest X-ray. Massive haemothorax refers to a large volume of blood in the pleural space, which can impair physiological function by causing blood loss, reducing lung volume for gas exchange, and compressing thoracic structures such as the heart and IVC.

The management of haemothorax involves replacing lost blood volume and decompressing the chest. This is done through supplemental oxygen, IV access and cross-matching blood, IV fluid therapy, and the insertion of a chest tube. The chest tube is connected to an underwater seal and helps drain the fluid, pus, air, or blood from the pleural space. In cases where there is prompt drainage of a large amount of blood, ongoing significant blood loss, or the need for blood transfusion, thoracotomy and ligation of bleeding thoracic vessels may be necessary. It is important to have two IV accesses prior to inserting the chest drain to prevent a drop in blood pressure.

In summary, haemothorax is the accumulation of blood in the pleural cavity due to chest trauma. Managing haemothorax involves replacing lost blood volume and decompressing the chest through various interventions, including the insertion of a chest tube. Prompt intervention may be required in cases of significant blood loss or ongoing need for blood transfusion.

Traumatic aortic rupture, also known as traumatic aortic disruption or transection, occurs when the aorta is torn or ruptured due to physical trauma. This condition often leads to sudden death because of severe bleeding. Motor vehicle accidents and falls from great heights are the most common causes of this injury.

The patients with the highest chances of survival are those who have an incomplete tear near the ligamentum arteriosum of the proximal descending aorta, close to where the left subclavian artery branches off. The presence of an intact adventitial layer or contained mediastinal hematoma helps maintain continuity and prevents immediate bleeding and death. If promptly identified and treated, survivors of these injuries can recover. In cases where traumatic aortic rupture leads to sudden death, approximately 50% of patients have damage at the aortic isthmus, while around 15% have damage in either the ascending aorta or the aortic arch.

Initial chest X-rays may show signs consistent with a traumatic aortic injury. However, false-positive and false-negative results can occur, and sometimes there may be no abnormalities visible on the X-ray. Some of the possible X-ray findings include a widened mediastinum, hazy left lung field, obliteration of the aortic knob, fractures of the 1st and 2nd ribs, deviation of the trachea to the right, presence of a pleural cap, elevation and rightward shift of the right mainstem bronchus, depression of the left mainstem bronchus, obliteration of the space between the pulmonary artery and aorta, and deviation of the esophagus or NG tube to the right.

A helical contrast-enhanced CT scan of the chest is the preferred initial investigation for suspected blunt aortic injury. It has proven to be highly accurate, with close to 100% sensitivity and specificity. CT scanning should be performed liberally, as chest X-ray findings can be unreliable. However, hemodynamically unstable patients should not be placed in a CT scanner. If the CT results are inconclusive, aortography or trans-oesophageal echo can be performed for further evaluation.

Immediate surgical intervention is necessary for these injuries. Endovascular repair is the most common method used and has excellent short-term outcomes. Open repair may also be performed depending on the circumstances. It is important to control heart rate and blood pressure during stabilization to reduce the risk of rupture. Pain should be managed with appropriate analgesic

A needle cricothyroidotomy is a procedure used in emergency situations to provide oxygenation when intubation and oxygenation are not possible. It is typically performed when a patient cannot be intubated or oxygenated. There are certain conditions that make this procedure contraindicated, such as local infection, distorted anatomy, previous failed attempts, and swelling or mass lesions.

To perform a needle cricothyroidotomy, the necessary equipment should be assembled and prepared. The patient should be positioned supine with their neck in a neutral position. The neck should be cleaned in a sterile manner using antiseptic swabs. If time allows, the area should be anesthetized locally. A 12 or 14 gauge over-the-needle catheter should be assembled to a 10 mL syringe.

The cricothyroid membrane, located between the thyroid and cricoid cartilage, should be identified anteriorly. The trachea should be stabilized with the thumb and forefinger of one hand. Using the other hand, the skin should be punctured in the midline with the needle over the cricothyroid membrane. The needle should be directed at a 45° angle caudally while negative pressure is applied to the syringe. Needle aspiration should be maintained as the needle is inserted through the lower half of the cricothyroid membrane, with air aspiration indicating entry into the tracheal lumen.

Once the needle is in place, the syringe and needle should be removed while the catheter is advanced to the hub. The oxygen catheter should be attached and the airway secured. It is important to be aware of possible complications, such as technique failure, cannula obstruction or dislodgement, injury to local structures, and surgical emphysema if high flow oxygen is administered through a malpositioned cannula.

A Focussed Assessment with Sonography for Trauma (FAST) scan is a point-of-care ultrasound examination conducted when a trauma patient arrives. Its primary purpose is to identify the presence of intra-abdominal free fluid, which is typically assumed to be haemoperitoneum in the context of trauma. This information helps healthcare providers make decisions regarding further management of the patient.

The sensitivity of FAST scanning for detecting intraperitoneal fluid is approximately 90%, while its specificity is around 95%. However, its sensitivity for detecting solid organ injuries is much lower. As a result, FAST scanning has largely replaced diagnostic peritoneal lavage as the preferred initial method for assessing haemoperitoneum.

During a standard FAST scan, four regions are assessed. The first is the subxiphoid transverse view, which is used to check for pericardial effusion and left lobe liver injuries. The second is the longitudinal view of the right upper quadrant, which helps identify right liver injuries, right kidney injuries, and fluid in the hepatorenal recess (Morison’s pouch). The third is the longitudinal view of the left upper quadrant, which is used to assess for splenic injury and left kidney injury. Lastly, the transverse and longitudinal views of the suprapubic region are examined to assess the bladder and fluid in the pouch of Douglas.

In addition to the standard FAST scan, an extended FAST or eFAST may also be performed. This involves examining the left and right thoracic regions to assess for the presence of pneumothorax and haemothorax.

The hepatorenal recess is the deepest part of the peritoneal cavity when a patient is lying flat. Therefore, it is the most likely area for fluid to accumulate in a supine position.

Shock is a condition characterized by inadequate tissue perfusion due to circulatory insufficiency. It can be caused by fluid loss or redistribution, as well as impaired cardiac output. The main causes of shock include haemorrhage, diarrhoea and vomiting, burns, diuresis, sepsis, neurogenic shock, anaphylaxis, massive pulmonary embolism, tension pneumothorax, cardiac tamponade, myocardial infarction, and myocarditis.

One common cause of shock is haemorrhage, which is frequently encountered in the emergency department. Haemorrhagic shock can be classified into different types based on the amount of blood loss. Type 1 haemorrhagic shock involves a blood loss of 15% or less, with less than 750 ml of blood loss. Patients with type 1 shock may have normal blood pressure and heart rate, with a respiratory rate of 12 to 20 breaths per minute.

Type 2 haemorrhagic shock involves a blood loss of 15 to 30%, with 750 to 1500 ml of blood loss. Patients with type 2 shock may have a pulse rate of 100 to 120 beats per minute and a respiratory rate of 20 to 30 breaths per minute. Blood pressure is typically normal in type 2 shock.

Type 3 haemorrhagic shock involves a blood loss of 30 to 40%, with 1.5 to 2 litres of blood loss. Patients with type 3 shock may have a pulse rate of 120 to 140 beats per minute and a respiratory rate of more than 30 breaths per minute. Urine output is decreased to 5-15 mls per hour.

Type 4 haemorrhagic shock involves a blood loss of more than 40%, with more than 2 litres of blood loss. Patients with type 4 shock may have a pulse rate of more than 140 beats per minute and a respiratory rate of more than 35 breaths per minute. They may also be drowsy, confused, and possibly experience loss of consciousness. Urine output may be minimal or absent.

In summary, shock is a condition characterized by inadequate tissue perfusion. Haemorrhage is a common cause of shock, and it can be classified into different types based on the amount of blood loss. Prompt recognition and management of shock are crucial in order to prevent further complications and improve patient outcomes

To estimate the total body surface area of burn, we need to consider the rule of nines. This rule divides the body into different regions, each representing a certain percentage of the total body surface area. According to the rule of nines, the left arm accounts for 9% of the total body surface area. Therefore, the estimated total body surface area of burn in this patient is 9%.

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.

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.

When assessing for cervical spine injury, it is recommended to use the Canadian C-spine rules. These rules help determine the risk level for a potential injury. High-risk factors include being over the age of 65, experiencing a dangerous mechanism of injury (such as a fall from a height or a high-speed motor vehicle collision), or having paraesthesia in the upper or lower limbs. Low-risk factors include being involved in a minor rear-end motor vehicle collision, being comfortable in a sitting position, being ambulatory since the injury, having no midline cervical spine tenderness, or experiencing a delayed onset of neck pain. If a person is unable to actively rotate their neck 45 degrees to the left and right, their risk level is considered low. If they have one of the low-risk factors and can actively rotate their neck, their risk level remains low.

If a high-risk factor is identified or if a low-risk factor is identified and the person is unable to actively rotate their neck, full in-line spinal immobilization should be maintained and imaging should be requested. Additionally, if a patient has risk factors for thoracic or lumbar spine injury, imaging should be requested. However, if a patient has low-risk factors for cervical spine injury, is pain-free, and can actively rotate their neck, full in-line spinal immobilization and imaging are not necessary.

NICE recommends CT as the primary imaging modality for cervical spine injury in adults aged 16 and older, while MRI is recommended as the primary imaging modality for children under 16.

Different mechanisms of spinal trauma can cause injury to the spine in predictable ways. The majority of cervical spine injuries are caused by flexion combined with rotation. Hyperflexion can result in compression of the anterior aspects of the vertebral bodies, stretching and tearing of the posterior ligament complex, chance fractures (also known as seatbelt fractures), flexion teardrop fractures, and odontoid peg fractures. Flexion and rotation can lead to disruption of the posterior ligament complex and posterior column, fractures of facet joints, lamina, transverse processes, and vertebral bodies, and avulsion of spinous processes. Hyperextension can cause injury to the anterior column, anterior fractures of the vertebral body, and potential retropulsion of bony fragments or discs into the spinal canal. Rotation can result in injury to the posterior ligament complex and facet joint dislocation.

The main sensory supply to the back of the scalp comes from the C2 and C3 cervical nerves. The scalp receives innervation from branches of both the trigeminal nerve and the cervical nerves, as depicted in the illustration in the notes. The C2 and C3 cervical nerves are primarily responsible for supplying sensation to the posterior scalp.

Further Reading:

The scalp is the area of the head that is bordered by the face in the front and the neck on the sides and back. It consists of several layers, including the skin, connective tissue, aponeurosis, loose connective tissue, and periosteum of the skull. These layers provide protection and support to the underlying structures of the head.

The blood supply to the scalp primarily comes from branches of the external carotid artery and the ophthalmic artery, which is a branch of the internal carotid artery. These arteries provide oxygen and nutrients to the scalp tissues.

The scalp also has a complex venous drainage system, which is divided into superficial and deep networks. The superficial veins correspond to the arterial branches and are responsible for draining blood from the scalp. The deep venous network is drained by the pterygoid venous plexus.

In terms of innervation, the scalp receives sensory input from branches of the trigeminal nerve and the cervical nerves. These nerves transmit sensory information from the scalp to the brain, allowing us to perceive touch, pain, and temperature in this area.

If an adult with a head injury experiences more than one episode of vomiting, it is recommended to undergo a CT scan of the head. There are several criteria for an urgent CT scan in individuals with a head injury, including a Glasgow Coma Scale (GCS) score of less than 13 on initial assessment in the emergency department (ED), a GCS score of less than 15 at 2 hours after the injury on assessment in the ED, suspected open or depressed skull fracture, any sign of basal skull fracture (such as haemotympanum, ‘panda’ eyes, cerebrospinal fluid leakage from the ear or nose, or Battle’s sign), post-traumatic seizure, new focal neurological deficit, and being on anticoagulation medication. If any of these signs are present, a CT scan should be performed within 1 hour, except for patients on anticoagulation medication who should undergo a CT scan within 8 hours if none of the other signs are present. However, if a patient on anticoagulation medication has any of the other signs, the CT scan should be performed within 1 hour.

– Dangerous mechanism of injury (high-speed road traffic accident, fall from a height.

Intubation is necessary for patients with a compromised airway. In comatose patients, a Glasgow Coma Scale (GCS) score of 8 or less indicates the need for intubation. According to NICE guidelines, immediate intubation and ventilation are advised in cases of coma where the patient is not responsive to commands, not speaking, and not opening their eyes. Other indications for intubation include the loss of protective laryngeal reflexes, ventilatory insufficiency as indicated by abnormal blood gases, spontaneous hyperventilation, irregular respirations, significantly deteriorating conscious level, unstable fractures of the facial skeleton, copious bleeding into the mouth, and seizures. In certain cases, intubation and ventilation should be performed before the patient begins their journey.

This patient is showing a slightly elevated heart rate and respiratory rate, as well as a slightly reduced urine output. These signs indicate that the patient has experienced a class II haemorrhage at this point. It is important to be able to recognize the degree of blood loss based on vital sign and mental status abnormalities. The Advanced Trauma Life Support (ATLS) haemorrhagic shock classification provides a way to link the amount of blood loss to expected physiological responses in a healthy 70 kg patient. In a 70 kg male patient, the total circulating blood volume is approximately five liters, which accounts for about 7% of their total body weight.

The ATLS haemorrhagic shock classification is summarized as follows:

CLASS I:
– Blood loss: Up to 750 mL
– Blood loss (% blood volume): Up to 15%
– Pulse rate: Less than 100 bpm
– Systolic BP: Normal
– Pulse pressure: Normal (or increased)
– Respiratory rate: 14-20 breaths per minute
– Urine output: Greater than 30 mL/hr
– CNS/mental status: Slightly anxious

CLASS II:
– Blood loss: 750-1500 mL
– Blood loss (% blood volume): 15-30%
– Pulse rate: 100-120 bpm
– Systolic BP: Normal

The most recent ATLS guidelines recommend using either the jaw-thrust or chin-lift techniques as the initial approach to open the airway in trauma patients. It is important to avoid moving the head and neck in patients with suspected cervical spine injuries. However, if the patient is unconscious and does not have a gag reflex, temporarily placing an oropharyngeal airway can be beneficial.

To perform the chin-lift technique, gently place your fingers under the mandible and lift it upwards to bring the chin forward. Use your thumb to slightly depress the lower lip and open the mouth. Alternatively, you can place your thumb behind the lower incisors while gently lifting the chin. It is crucial not to hyperextend the neck during the chin-lift technique.

For the jaw thrust technique, place one hand on each side of the mandible and push it forward. This can be done in conjunction with a bag-mask device to achieve a good seal and provide adequate ventilation. Just like with the chin-lift technique, be cautious not to extend the patient’s neck.

Circumferential burns on the thorax can limit the expansion of the chest and hinder proper ventilation. When burns penetrate deeply, they can cause the formation of dead tissue called eschar, which is usually white or black in color. This eschar is contracted and inflexible compared to healthy tissue, leading to restricted movement and impaired breathing. In some cases, burns on the thorax can result in respiratory failure. Marjolin’s ulcer, a rare condition, refers to the development of squamous cell carcinoma in burnt or scarred tissue. Burn injuries often lead to the release of excess potassium into the bloodstream, which can cause hyperkalemia. Carbon monoxide poisoning typically occurs when someone inhales CO over a prolonged period, usually due to incomplete combustion of hydrocarbons. However, the history provided in this case does not align with prolonged exposure to carbon monoxide.

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.

The Canadian C-spine assessment includes evaluating for tenderness along the midline of the spine, checking for any abnormal sensations in the limbs, and assessing the ability to rotate the neck 45 degrees to the left and right. While a significant portion of the assessment relies on gathering information from the patient’s history, there are also physical examination components involved. These include testing for tenderness along the midline of the cervical spine, asking the patient to perform neck rotations, ensuring they are comfortable in a sitting position, and assessing for any sensory deficits in the limbs. It is important to note that any reported paraesthesia in the upper or lower limbs can also be taken into consideration during the assessment.

When assessing for cervical spine injury, it is recommended to use the Canadian C-spine rules. These rules help determine the risk level for a potential injury. High-risk factors include being over the age of 65, experiencing a dangerous mechanism of injury (such as a fall from a height or a high-speed motor vehicle collision), or having paraesthesia in the upper or lower limbs. Low-risk factors include being involved in a minor rear-end motor vehicle collision, being comfortable in a sitting position, being ambulatory since the injury, having no midline cervical spine tenderness, or experiencing a delayed onset of neck pain. If a person is unable to actively rotate their neck 45 degrees to the left and right, their risk level is considered low. If they have one of the low-risk factors and can actively rotate their neck, their risk level remains low.

If a high-risk factor is identified or if a low-risk factor is identified and the person is unable to actively rotate their neck, full in-line spinal immobilization should be maintained and imaging should be requested. Additionally, if a patient has risk factors for thoracic or lumbar spine injury, imaging should be requested. However, if a patient has low-risk factors for cervical spine injury, is pain-free, and can actively rotate their neck, full in-line spinal immobilization and imaging are not necessary.

NICE recommends CT as the primary imaging modality for cervical spine injury in adults aged 16 and older, while MRI is recommended as the primary imaging modality for children under 16.

Different mechanisms of spinal trauma can cause injury to the spine in predictable ways. The majority of cervical spine injuries are caused by flexion combined with rotation. Hyperflexion can result in compression of the anterior aspects of the vertebral bodies, stretching and tearing of the posterior ligament complex, chance fractures (also known as seatbelt fractures), flexion teardrop fractures, and odontoid peg fractures. Flexion and rotation can lead to disruption of the posterior ligament complex and posterior column, fractures of facet joints, lamina, transverse processes, and vertebral bodies, and avulsion of spinous processes. Hyperextension can cause injury to the anterior column, anterior fractures of the vertebral body, and potential retropulsion of bony fragments or discs into the spinal canal. Rotation can result in injury to the posterior ligament complex and facet joint dislocation.

Haemothorax often leads to reduced or absent air entry, a dull percussion sound, and decreased fremitus on the affected side. Commonly observed symptoms in patients with haemothorax include decreased or absent air entry, a dull percussion note when the affected side is tapped, reduced fremitus on the affected side, and in cases of massive haemothorax, tracheal deviation away from the affected side. Other signs that may be present include a rapid heart rate (tachycardia), rapid breathing (tachypnoea), low blood pressure (hypotension), and signs of shock.

Haemothorax is the accumulation of blood in the pleural cavity of the chest, usually resulting from chest trauma. It can be difficult to differentiate from other causes of pleural effusion on a chest X-ray. Massive haemothorax refers to a large volume of blood in the pleural space, which can impair physiological function by causing blood loss, reducing lung volume for gas exchange, and compressing thoracic structures such as the heart and IVC.

The management of haemothorax involves replacing lost blood volume and decompressing the chest. This is done through supplemental oxygen, IV access and cross-matching blood, IV fluid therapy, and the insertion of a chest tube. The chest tube is connected to an underwater seal and helps drain the fluid, pus, air, or blood from the pleural space. In cases where there is prompt drainage of a large amount of blood, ongoing significant blood loss, or the need for blood transfusion, thoracotomy and ligation of bleeding thoracic vessels may be necessary. It is important to have two IV accesses prior to inserting the chest drain to prevent a drop in blood pressure.

In summary, haemothorax is the accumulation of blood in the pleural cavity due to chest trauma. Managing haemothorax involves replacing lost blood volume and decompressing the chest through various interventions, including the insertion of a chest tube. Prompt intervention may be required in cases of significant blood loss or ongoing need for blood transfusion.

When it comes to managing acute burns, Hartmann’s or lactated Ringers are the preferred intravenous fluids. There is no scientific evidence to support the use of colloids in burn management. In the United Kingdom, Hartmann’s solution is the most commonly used fluid for this purpose.

TBSA, or Total Body Surface Area, is a method commonly used to estimate the size of small burns and very large burns by including the area of unburnt skin. However, it is not considered a reliable method for medium-sized burns.

A needle cricothyroidotomy is a procedure used in emergency situations to provide oxygenation when intubation and oxygenation are not possible. It is typically performed when a patient cannot be intubated or oxygenated. There are certain conditions that make this procedure contraindicated, such as local infection, distorted anatomy, previous failed attempts, and swelling or mass lesions.

To perform a needle cricothyroidotomy, the necessary equipment should be assembled and prepared. The patient should be positioned supine with their neck in a neutral position. The neck should be cleaned in a sterile manner using antiseptic swabs. If time allows, the area should be anesthetized locally. A 12 or 14 gauge over-the-needle catheter should be assembled to a 10 mL syringe.

The cricothyroid membrane, located between the thyroid and cricoid cartilage, should be identified anteriorly. The trachea should be stabilized with the thumb and forefinger of one hand. Using the other hand, the skin should be punctured in the midline with the needle over the cricothyroid membrane. The needle should be directed at a 45° angle caudally while negative pressure is applied to the syringe. Needle aspiration should be maintained as the needle is inserted through the lower half of the cricothyroid membrane, with air aspiration indicating entry into the tracheal lumen.

Once the needle is in place, the syringe and needle should be removed while the catheter is advanced to the hub. The oxygen catheter should be attached and the airway secured. It is important to be aware of possible complications, such as technique failure, cannula obstruction or dislodgement, injury to local structures, and surgical emphysema if high flow oxygen is administered through a malpositioned cannula.

ATLS guidelines now suggest administering only 1 liter of crystalloid fluid during the initial assessment. If patients do not respond to the crystalloid, it is recommended to quickly transition to blood products. Studies have shown that infusing more than 1.5 liters of crystalloid fluid is associated with higher mortality rates in trauma cases. Therefore, it is advised to prioritize the early use of blood products and avoid large volumes of crystalloid fluid in trauma patients. In cases where it is necessary, massive transfusion should be considered, defined as the transfusion of more than 10 units of blood in 24 hours or more than 4 units of blood in one hour. For patients with evidence of Class III and IV hemorrhage, early resuscitation with blood and blood products in low ratios is recommended.

Based on the findings of significant trials, such as the CRASH-2 study, the use of tranexamic acid is now recommended within 3 hours. This involves administering a loading dose of 1 gram intravenously over 10 minutes, followed by an infusion of 1 gram over eight hours. In some regions, tranexamic acid is also being utilized in the prehospital setting.

This patient is showing significant signs of distress, including a highly elevated heart rate and respiratory rate, as well as very little urine output. Additionally, they are experiencing drowsiness, lethargy, and confusion. These symptoms indicate that the patient has suffered a class IV haemorrhage at this stage.

Recognizing the extent of blood loss based on vital signs and mental status abnormalities is a crucial skill. The Advanced Trauma Life Support (ATLS) classification for haemorrhagic shock correlates the amount of blood loss with expected physiological responses in a healthy 70 kg patient. In a 70 kg male patient, the total circulating blood volume is approximately five litres, accounting for around 7% of their total body weight.

The ATLS haemorrhagic shock classification is summarized as follows:

CLASS I
Blood loss (mL): Up to 750
Blood loss (% blood volume): Up to 15%
Pulse rate (bpm): <100
Systolic BP: Normal
Pulse pressure: Normal (or increased)
Respiratory rate: 14-20
Urine output (ml/hr): >30
CNS/mental status: Slightly anxious

CLASS II
Blood loss (mL): 750-1500
Blood loss (% blood volume): 15-30%
Pulse rate (bpm): 100-120
Systolic BP: Normal
Pulse pressure: Decreased
Respiratory rate: 20-30
Urine output (ml/hr): 20-30
CNS/mental status: Mildly anxious

CLASS III
Blood loss (mL): 1500-2000
Blood loss (% blood volume): 30-40%
Pulse rate (bpm): 120-140
Systolic BP: Decreased

CNS/mental status: Confused, lethargic

Patients with head injuries who show any signs of basal skull fracture, such as haemotympanum, ‘panda’ eyes, cerebrospinal fluid leakage from the ear or nose, or Battle’s sign, should undergo urgent CT imaging. Additionally, the following indications also warrant a CT scan: a Glasgow Coma Scale (GCS) score of less than 13 on initial assessment in the emergency department (ED), a GCS score of less than 15 at 2 hours after the injury on assessment in the ED, suspected open or depressed skull fracture, post-traumatic seizure, new focal neurological deficit, greater than 1 episode of vomiting, or the patient being on anticoagulation. If any of these signs are present, a CT scan should be performed within 1 hour, except for patients on anticoagulation who should have a CT scan within 8 hours if they do not have any other signs. However, if patients on anticoagulation do have any of the other signs, the CT scan should be performed within 1 hour.

The ATLS guidelines categorize chest injuries in trauma into two groups: life-threatening injuries that require immediate identification and treatment in the primary survey, and potentially life-threatening injuries that should be identified and treated in the secondary survey.

During the primary survey, the focus is on identifying and treating life-threatening thoracic injuries. These include airway obstruction, tracheobronchial tree injury, tension pneumothorax, open pneumothorax, massive haemothorax, and cardiac tamponade. Prompt recognition and intervention are crucial in order to prevent further deterioration and potential fatality.

In the secondary survey, attention is given to potentially life-threatening injuries that may not be immediately apparent. These include simple pneumothorax, haemothorax, flail chest, pulmonary contusion, blunt cardiac injury, traumatic aortic disruption, traumatic diaphragmatic injury, and blunt oesophageal rupture. These injuries may not pose an immediate threat to life, but they still require identification and appropriate management to prevent complications and ensure optimal patient outcomes.

By dividing chest injuries into these two categories and addressing them in a systematic manner, healthcare providers can effectively prioritize and manage trauma patients, ultimately improving their chances of survival and recovery.
