Disorders of Consciousness: Practical Management in an Emergency Room

Lowering of the level of consciousness is a very common presentation at the emergency room, often without any history that helps finding an etiology. This emergency requires quick empirical measures to reduce neuronal mortality, with additional protection against sequelae. According to the Advanced Cardiac Life Support (ACLS) guidelines, there are current emergency neurological support protocols, such as the Emergency Neurological Life Support (ENLS) created by the Neurocritical Care Society. The present paper shows how to approach unconscious patients, highlighting possible etiologies and proposed treatments.
