Se comenta la experiencia de 10 años en cuanto a la morbilidad y mortalidad de pacientes obstétricas en una unidad de cuidados intensivos.Objectives: To determine the rate of admission to an obstetrical Intensive Care Unit (O-ICU), maternal mortality rate and the main factors associated with it. Methods: This was a retrospective study, analyzing all the admission to an O-ICU between January 1, 2009, and november 28, 2016. The registries were completed since the first day of recruitment until discharge or death. Results: Among 2,145 patients admitted to the O-ICU during the study period, maternal mortality was of 4.6% (n = 100). The three main causes of hospitalization were hypertensive disorders (47.1%), bleeding disorders (18.9%) and infectious complications (5.4%). The Receiver Operating Characteristic (ROC) curve showed the patient’s age was the variable with the largest area under the curve (0.569) in relation to mortality. Applying the linear regression model gave as a result that age, Mean Arterial Pressure (MAP), platelets at admission and haemoglobin are significant (P ≤ 0.001) as predictive factors for mortality. The Weight Estimation test also showed significance for platelets count and MAP at admission. Conclusion: From the analysis done, it showed that the patient’s age, MAP and platelets at admission are the most important parameters to predict mortality
