Critical care in obstetrics

Pregnancy is a normal physiologic process with the potential for pathologic states. Pregnancy has several unique characteristics including an utero-placental interface, a physiologic stress that can cause pathologic states to develop, and a maternal–foetal interface that can affect two lives simultaneously or in isolation. Critical illness in pregnant women may result from deteriorating preexisting conditions, diseases that are co-incidental to pregnancy, or pregnancy-specific conditions. Successful maternal and neonatal outcomes for parturients admitted to a maternal critical care facility are largely dependent on a multidisciplinary input to medical or surgical condition from critical care physicians, obstetric anaesthesiologists, obstetricians, obstetric physicians, foetal medicine specialists, neonatologists, and concerned specialists. Pregnant women requiring maternal critical care unit admission are relatively low in developed nations and range from 0.9% to 1%; but in our country, the admission rates of critically ill parturients range from 3% to 8%. Two-thirds of pregnant women requiring critical care are often unanticipated at the time of conception. In this review, we will look at critical illnesses in pregnant women with a specific focus on pregnancy-induced illnesses.
