Abstract

Anesthesia for obstetrical emergencies presents some of the most difficult decision making quandaries in anesthesiology due to the double considerations of both mother and fetus. Concerns for the mother often compete with concerns for the fetus. In the following chapter, several topics will be discussed including emergency cesarean section in patients with comorbidities such as asthma, morbid obesity and eclampsia. A cesarean section may have to be done without a spinal, epidural, or general anesthetic; that is a cesarean section done using only local anesthesia. Non-hemorrhagic emergencies during labor such as umbilical cord prolapse, breach presentation and shoulder dystocia are elaborated. Recommendations for hemorrhage- antepartum due to placenta previa, placental abruption, trial of labor after cesarean section, and uterine rupture; as well as those for postpartum- hemorrhage due to placenta accreta, increta, percreta, as well as uterine atony and uterine inversion are discussed. The pregnant patient undergoing nonobstetrical surgery presents with other challenges that are also addressed in the chapter.
