Predictors of mortality and neurological function in ICU patients recovering from cardiac arrest: A Spanish nationwide prospective cohort study.
2020
OBJECTIVE: To identify predictors of mortality and neurological function in adult ICU patients recovering from cardiac arrest. DESIGN: A prospective cohort multicenter study was carried out. SETTING: Forty-six polyvalent ICUs. PATIENTS: A total of 595 patients recovering from out-of-hospital cardiac arrest (OHCA, n=285) or in-hospital cardiac arrest (IHCA, n=310). MAIN OUTCOME VARIABLES: Survival and recovery of neurological function. RESULTS: The mean cardiopulmonary resuscitation time was 18min (range 10-30). Moderate hypothermia was used in 197 patients, and 150 underwent percutaneous coronary intervention (PCI). Return of spontaneous circulation (ROSC) was achieved within 20min in 370 patients. Variables associated to mortality (ICU and in-hospital) were age (odds ratio [OR]=1.0, 95%CI 1.0-1.0 per year), non-cardiac origin of cardiac arrest (OR=2.16, 95%CI 1.38-3.38; P=0.001) and ROSC >20min (OR=3.07, 95%CI 1.97-4.78; P 20min were predictors of mortality. In contrast, cardiac arrest of cardiac origin, ROSC <20min, and defibrillable rhythms were associated to unfavorable neurological outcomes.
