Intensive Care After Cardiac Arrest.

Abstract

Cardiac arrest causes an abrupt cessation of circulation which rapidly leads to global ischemia and hypoxia. Immediate and competent care is vital, and even when the circulation has been restored, there is a profound risk of patients never regaining consciousness due to hypoxic-ischemic brain injury, or death due recurrent cardiac arrest or multi-organ failure. The complex pattern of symptoms seen in resuscitated cardiac arrest patients, has been termed post-cardiac arrest syndrome, and encompasses brain injury, myocardial dysfunction, systemic ischemia and reperfusion response, and the pathological process that caused the cardiac arrest. This educational review describes the intensive care for resuscitated cardiac arrest patients and provides discussions of current evidence, and emerging trends for key therapeutic areas.
