People who survive cardiopulmonary resuscitation (CPR) after cardiac arrest, have a wide range of outcomes including complete neurological recovery, coma, compromised cognitive function and death.

Injury of the brain parenchyma starts immediately after a cardiac arrest, during CPR and return of spontaneous circulation. The severity of the ischemic injury will define the neurological outcome. The first step needed to determine a neurological prognosis is the clinical exam, with the help of electroencephalography, somatosensory evoked potentials, neuroimaging, and serum biomarkers.

Between 10 and 15% of patients with brain injury after a cardiac arrest, develop brain death and become potential candidates for organ donation. A premature withdrawal of vital support can hamper the possibility of organ donation. The patients with higher risk of developing brain death can be identified early based on neurological criteria.

The neurologist has a major role in the approach of patients with brain injury after cardiac arrest and the decision making with legal and ethical consequences.

Keywords : Cardiac arrest; hypoxic ischemic encephalopathy; prognostication; brain; coma (MeSH).
