Objective:The objective of this study was to analyze the clinical profile of patients with in-hospital cardiac arrest using the Utstein style.Methods:This study is an observational, prospective, longitudinal study of patients with cardiac arrest treated in intensive care units over a period of 1 year.Results:The study included 89 patients who underwent cardiopulmonary resuscitation maneuvers. The cohort was 51.6% male with a mean age 59.0 years. The episodes occurred during the daytime in 64.6% of cases. Asystole/bradyarrhythmia was the most frequent initial rhythm (42.7%). Most patients who exhibited a spontaneous return of circulation experienced recurrent cardiac arrest, especially within the first 24 hours (61.4%). The mean time elapsed between hospital admission and the occurrence of cardiac arrest was 10.3 days, the mean time between cardiac arrest and cardiopulmonary resuscitation was 0.68 min, the mean time between cardiac arrest and defibrillation was 7.1 min, and the mean duration of cardiopulmonary resuscitation was 16.3 min. Associations between gender and the duration of cardiopulmonary resuscitation (19.2 min in women versus 13.5 min in men, p = 0.02), the duration of cardiopulmonary resuscitation and the return of spontaneous circulation (10.8 min versus 30.7 min, p < 0.001) and heart disease and age (60.6 years versus 53.6, p < 0.001) were identified. The immediate survival rates after cardiac arrest, until hospital discharge and 6 months after discharge were 71%, 9% and 6%, respectively.Conclusions:The main initial rhythm detected was asystole/bradyarrhythmia; the interval between cardiac arrest and cardiopulmonary resuscitation was short, but defibrillation was delayed. Women received cardiopulmonary resuscitation for longer periods than men. The in-hospital survival rate was low.
