Resumption of spontaneous circulation (ROSC) after prolonged, complete, whole-body ischemia is an unnatural pathophysiological state created by successful cardiopulmonary resuscitation (CPR). Post–cardiac arrest patients are treated by multiple teams of providers both outside and inside the hospital. Evidence exists of considerable variation in post–cardiac arrest treatment and patient outcome between institutions. Therefore, a well-thought-out multidisciplinary approach for comprehensive care must be established and executed consistently. Aim of work: The objective is to detect different sequelae following cardiopulmonary arrest and to evaluate them both clinically and laboratory and the most important factors affecting the outcome.Patients and methods: 87 patients who were admitted in the emergency department and experienced cardiopulmonary arrest and resuscitation during a period of six months duration.Results: Out of 87 patients, 65 were successfully resuscitated representing 74.7% of patients with return of circulation; however the resuscitation of the rest of the patients (22) failed representing 25.3% of cases. None survived to discharge.
