Use a systematic approach based on ABCDE6 to assess and treat an acutely injured patient. The goal is to manage any life-threatening conditions and identify any emergent concerns, especially in a neurotrauma patient who may present with other multisystem injuries. Show
Airway with cervical spine protectionAssess for airway stabilityAttempt to elicit a response from the patient.Look for signs of airway obstruction (use of accessory muscles, paradoxical chest movements, see-saw respirations). Listen for any upper-airway noises, breath sounds. Are they absent, diminished or noisy? Noisy ventilations indicate a partial airway obstruction by either the tongue or foreign material. Assess for soiled airwayHaemorrhage, vomiting and swelling from facial trauma are common causes of airway obstruction in patients with TBI. These should be removed with suction. Top of page Attempt simple airway manoeuvres if required
Caution: Nasopharyngeal airways (NPA) should not be inserted in patients with a head injury in whom a base of skull fracture has not been excluded.7 Secure the airway if necessary (treat airway obstruction as a medical emergency)Consider intubation early if there are any signs of:
It is vital that intubation is carried out by a person skilled in airway management. Intubation may cause a transient increase in ICP, which may lead to secondary brain injury. Attempts at intubation can also invoke hypoxia. Preference is given to performing a rapid sequence induction with sedation and paralysis. Maintain full spinal precautions if indicatedSuspect spinal injuries in polytrauma patients, especially where TBI is involved. Ensure cervical collar, head blocks or in-line immobilisation is maintained throughout patient care.Breathing and ventilationAssessing for adequate ventilatory effort is essential in the early stages of TBI. Oxygen administrationAdminister oxygen to achieve oxygen saturations between 94-98%. Record the oxygen saturation (SpO2)Adequate oxygenation to the brain is an essential element in avoiding secondary brain injury. Monitor the SpO2 and maintain it between 94-98%.8 9 Saturations below this range is associated with poorer outcomes.Assess the chestCount the patient’s respiration rate and note the depth and adequacy of their breathing. Auscultate the chest for breath sounds and assess for any wheeze, stridor or decreased air entry. Be mindful that thoracic injuries may have also occurred.Circulation with haemorrhage controlAssess circulation and perfusionCheck heart rate and blood pressure.Maintain an SBP greater than 110 mmHg in order to sustain cerebral perfusion and prevent further brain injury10. A slow, forceful pulse may indicate intracranial hypertension and impending uncal herniation.Inspect for any signs of external haemorrhage and apply direct pressure to any wounds. Consider the potential for significant internal bleeding related to the mechanism of injury, which may lead to signs and symptoms of shock.Insert two large-bore peripheral intravenous (IV) cannulas. If access is difficult consider intraosseous insertion if the equipment/skills are available.Commence fluid resuscitation as indicated.If signs of shock are present, establish a cause and treat aggressively with IV fluid to raise the blood pressure and improve cerebral perfusion. Hypotension is not generally associated with isolated head Injury. If hypotension is present, identify the cause. Disability: neurological statusAssess level of consciousnessAn AVPU assessment (Alert, responds to Voice, responds to Pain, Unresponsive) should be completed along with a check of pupillary response and size. A more detailed neurological assessment using the GCS will be performed in the secondary survey.Test blood sugar levelsEnsure that any alterations in the patient’s level of consciousness are not related to a metabolic cause. Top of page Exposure/environmental controlRemove all clothing from the patient and assess to ensure there are no other obvious, life-threatening injuries present. Keep the patient normothermic through passive re-warming with blankets and a warm environment.
A head injury occurs as a result of trauma to the scalp, skull or brain and may be classified as closed (no cut to the skin) or penetrating (skin and/or bone of the skull is broken). Head injury symptoms may occur immediately following trauma or develop slowly over time. Your doctor may perform a physical and neurologic exam along with head CT, head MRI or head x-ray to assess the nature and severity of your injury and determine appropriate treatment. While patients with minor head injuries may be observed and treated with medication, more serious traumatic brain injuries may require emergency care to remove blood clots or relieve pressure on the brain.
A head injury occurs as a result of trauma to the scalp, skull or brain. Head injuries are classified as closed, in which there is no cut or laceration to the skin, or penetrating, in which the skin and/or bone of the skull is broken. Traumatic brain injuries range from mild (called mild traumatic brain injury) to severe. The symptoms of a head injury may occur immediately following trauma, or they may develop slowly over several hours or days. Specific types and symptoms of head injuries include:
In infants and toddlers who cannot communicate, signs of a head injury include:
Patients who exhibit symptoms of a head injury should seek immediate medical attention. top of page
The treatment of head injuries depends on the type of injury and the patient's condition. To assess the severity of a head injury, a physician may perform a physical and neurologic exam and imaging tests such as:
top of page
Consider seeking immediate medical attention with any form of head injury as the consequences of unrecognized or inappropriately treated head injury may be potenaatially serious. Patients with minor head injuries will be observed and treated for symptoms, including pain medication for headache and medications to control nausea and vomiting. If you have symptoms of a simple concussion, you should avoid being overly active. Your physician will advise you as to when you can return to your normal daily routine and sporting activities. More serious, traumatic brain injuries will require individualized and often emergency care, such as surgery to remove blood clots and relieve pressure on the brain. top of page Which test, procedure or treatment is best for me?top of page
