Neurocritical care
-
Cardiac arrest is the most common cause of death in North America. Neurocritical care interventions, including therapeutic hypothermia (TH), have significantly improved neurological outcomes in patients successfully resuscitated from cardiac arrest. Therefore, resuscitation following cardiac arrest was chosen as an Emergency Neurological Life Support protocol. ⋯ This protocol will review induction, maintenance, and re-warming phases of TH, along with management of TH side effects. Aggressive shivering suppression is necessary with this treatment to ensure the maintenance of a target temperature. Ancillary testing, including electrocardiography, computed tomography imaging of the brain, continuous electroencephalography, monitoring, and correction of electrolyte, blood gas, and hematocrit changes are also necessary to optimize outcomes.

Bacterial meningitis and viral encephalitis, particularly herpes simplex encephalitis (HSE), are severe neurological infections that, if not treated promptly and effectively, lead to poor neurological outcome or death. Because treatment is more effective if given early, the topic of meningitis and encephalitis was chosen as an Emergency Neurological Life Support protocol. ⋯ Though uncommon in its full form, the typical clinical triad of headache, fever, and neck stiffness should alert the clinical practitioner to the syndromes. Early attention to the airway and maintaining normotension is crucial in treatment of these patients, as is rapid treatment with anti-infectives and, in some cases, corticosteroids.

Sustained intracranial hypertension and acute brain herniation are "brain codes," signifying catastrophic neurological events that require immediate recognition and treatment to prevent irreversible injury and death. As in cardiac arrest, evidence supports the organized implementation of a stepwise management algorithm. Because there are multiple etiologies and many treatments that can potentially reverse cerebral herniation, intracranial hypertension and herniation was chosen as an Emergency Neurological Life Support (ENLS) protocol.
-
Traumatic brain injury (TBI) was chosen as an Emergency Neurological Life Support topic due to its frequency, the impact of early intervention on outcomes for patients with TBI, and the need for an organized approach to the care of such patients within the emergency setting. This protocol was designed to enumerate the practice steps that should be considered within the first critical hour of neurological injury.

Traumatic spine injuries (TSIs) carry significantly high risks of morbidity, mortality, and exorbitant health care costs from associated medical needs following injury. For these reasons, TSI was chosen as an ENLS protocol. ⋯ Though the review focuses primarily on cervical spinal column injuries, thoracolumbar injuries are briefly discussed as well. The initial emergency department clinical evaluation of possible spinal fractures and cord injuries, along with the definitive early management of confirmed injuries, are also covered.
