ObjectiveTo identify the epidemiologic profile, maternal survival, and prognosis factors that might affect survival rates in the obstetric intensive care unit (ICU).MethodsA prospective cohort study was conducted between January 2007 and February 2009 in a tertiary referral ICU, Belo Horizonte, Brazil. Critical patients during pregnancy and puerperium were followed from admission until discharge or death. Maternal survival was assessed in association with the cause of ICU admission, grouped into direct or indirect obstetric causes, by Kaplan-Meier curves and log-rank tests.ResultsAmong 298 patients admitted to the ICU during the study period, mortality was 4.7% (n=14). Hypertensive disorders (46.0%), hemorrhage (15.9%), sepsis (14.2%), and heart disease (5.7%) were the main causes of admission. Half of the patients who died were admitted for direct obstetric reasons (n=7). Survival was statistically linked to the cause of admission: most survivors were admitted for a direct obstetric cause (75.5%; P=0.044). Maternal survival rates of patients admitted for indirect obstetric causes were lower than those admitted for direct obstetric causes (27.8 and 19.6 days, respectively; P=0.019).ConclusionThe main cause of admission was a decisive factor for maternal survival in the obstetric ICU. Direct obstetric complications had a better prognosis.© 2013.
