Emergency Neurologic Life Support (ENLS) is an educational program designed to provide users advisory instructions regarding management for the first few hours of a neurologic emergency. The content of the course is divided into 14 modules, each addressing a distinct category of neurological injury. ⋯ Certification and training in ENLS is hosted by the Neurocritical Care Society. This document introduces the concept of ENLS and describes revisions that constitute the third version.

Coma is an acute failure of neuronal systems governing arousal and awareness and represents a medical emergency. When encountering a comatose patient, the clinician must have an organized approach to detect easily remediable causes, prevent ongoing neurologic injury, and determine a hierarchical plan for diagnostic tests, treatments, and neuromonitoring. Coma was chosen as an Emergency Neurological Life Support protocol because timely medical and surgical interventions can be life-saving, and the initial work-up of such patients is critical to establishing a correct diagnosis.

Acute ischemic stroke is a neurological emergency that can be treated with time-sensitive interventions, including both intravenous thrombolysis and endovascular approaches to thrombus removal. Extensive study has demonstrated that rapid, protocolized, assessment and treatment is essential to improving neurological outcome. For this reason, acute ischemic stroke was chosen as an emergency neurological life support protocol. The protocol focuses on the first hour of medical care following the acute onset of a neurological deficit.

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, a brain code mandates the organized implementation of a stepwise management algorithm. The goal of this Emergency Neurological Life Support protocol is to implement an evidence-based, standardized approach to the evaluation and management of patients with intracranial hypertension and/or herniation.
