Background: Pregnant women are at risk to develop complications due to illness related to pregnancy or due to aggravation of pre– existing disease. Those patients with critical illness require close monitoring and intensive care.To determine the current spectrum of diseases requiring admissions in High dependency unit (HDU)/ intensive care unit (ICU) at a tertiary care hospital. Methods: A retrospective case series study and analysis of data from obstetric patients admitted for critical care management. Results: A total of 102 (1.6%) of patients among admitted to the hospital required ICU admissions. Among them 14% of patients were admitted to ICU for ventilator support. Pre-eclampsia and obstetrical hemorrhage were the common diagnosis and 9.8% of maternal deaths were seen in this group. Conclusion: Critically ill obstetric patients require a team approach of the obstetrician, anesthesiologist and intensive carespecialist for the optimal care of these patients.
