AbstractComplications of general anesthesia for cesarean section remain the leading cause of anesthesia-related maternal mortality. General anesthesia, however, is becoming less popular for obstetric anesthesia, and thus fewer cesarean sections are conducted using this technique. As the number of general anesthesia cases decrease, the number of difficult intubations witnessed and managed by residents decreases. In addition, patients who undergo general anesthesia may have co-morbidities which, while not contraindicating regional anesthesia, may increase the risk of providing anesthesia. We reviewed the medical records of 6 calendar years (1990-1995) at our busy tertiary center, to determine patient demographics, indications for cesarean section, indications for general anesthesia, time of day, and complications related to airway management. From 1990 through 1995, cesarean sections under general anesthesia decreased from 7.2% to 3.6% (P=0.0001), however, they were performed on parturients with more maternal diseases (17.2% to 35.8%; P=0.0034). Although the incidence of difficult intubations in those years ranged from 16.3% to 1.3%, only one failed intubation with resultant maternal mortality occurred. Few residency programs offer instruction on the difficult airway in the parturient population. Organized airway management programs specifically for the obstetric population may assist efforts to decrease the morbidity and mortality associated with the provision of general anesthesia for cesarean section.
