Objective: Despite the fact that obstetric cases constitute only a small portion of intensive care hospitalizations, maternal mortality still remains an important health problem in the world. In this study, we aimed to evaluate the frequency and reasons of admission of obstetric patients to the intensive care unit (ICU), as well as the ‘advanced’ treatments applied and the clinical outcomes. Materials and Methods: The medical records of 8800 obstetric patients who were admitted to the hospital between 2012-2017 were retrospectively reviewed. The demographic data, reasons for admission to the ICU, concomitant diseases, intensive care interventions (advanced monitoring, extracorporeal therapies, etc.) and clinical outcomes were evaluated. Results: Of the 8800 obstetric patients, 40 (0.45%) patients required intensive care. The mean age was 32.2±5 years. The mean duration of stay in the ICU was 4.3 days. The most common reasons for admission to the ICU were HELLP-Preeclampsia-Eclampsia in 16 (40%) patients and bleeding (due to disseminated intravascular coagulation, uterine perforation, uterine atonia) in 11 (27%) patients. Seventeen patients received invasive mechanical ventilation and 3 patients received non-invasive mechanical ventilation. Two patients received extracorporeal membrane oxygenation (ECMO), 4 patients received plasmapheresis and 5 patients received hemodiafiltration. Three patients died. One patient died of multiorgan failure secondary to HELLP (hemolysis, elevated liver enzymes, and low platelets) syndrome. Two patients died due to HELLP and intracerebral hemorrhage. Conclusion: Advanced intensive care settings where new-era technological equipment (ECMO, hemodiafiltration, advanced monitoring, etc.) is in-reach and employing a multidisciplinary approach in the ICU may decrease the maternal mortality and morbidity.
