This document discusses maternal sepsis, which is a life-threatening complication that affects over 60,000 women in the United States each year, resulting in around 2,000 deaths. Sepsis caused by infections is one of the leading causes of maternal mortality worldwide and may be preventable through increased awareness and prompt treatment. The new WHO definition classifies maternal sepsis as an organ dysfunction caused by infection during pregnancy, childbirth, or postpartum. Risk factors include procedures like cesarean sections and complications of delivery. Early identification through clinical signs, labs, and monitoring systems can help providers treat at-risk women more quickly and prevent sepsis. A multi-disciplinary approach in a maternal intensive care unit provides the best care for critically ill

- 32. Open intensive care unit model Patients are admitted under the care of an internist, family physician, surgeon, or any other primary attending physician, with the intensivists being available to provide their expertise via elective consultation The patient's primary physician determines the need for ICU admission and discharge. 10/15/2019 Dr.Hadi Saghaleini 32

- 34. Hybrid or transitional ICU or semi-closed ICU Semi-closed ICU is one in which critical care team provides direct patient care in collaboration with other 'privileged' physicians, who are also allowed to write orders. In this model, the primary treating physicians are not a part of the ICU team, but remain actively involved in their patients' care. Many surgical , maternal and cardiothoracic ICUs maintain this model. 10/15/2019 Dr.Hadi Saghaleini 34
