A Single-center Retrospective Cohort Study on Cesarean Section under General Anesthesia

Objective Neuraxial block is the most common anesthesia method for cesarean section (CS).However, for some urgent and high-risk cesarean delivery, general anesthesia (GA) also plays a very important role.We aimed to find out the reasons of choosing GA for CS in our center and the factors that may be related to the maternal and fetal outcomes.Methods We retrospectively selected and analyzed parturients who had CS procedures under GA in Peking Union Medical College Hospital from January 1, 2014 to December 31, 2016.Clinical data (baseline maternal status, preoperative status, perioperative information, maternal and fetal outcomes) of parturients and neonates were collected.We summarized the common reasons for applying general anesthesia, and compared the backto-ICU ratio and hospital stay time between parturients with different maternal ASA grade, gestational week and intraoperative blood loss, as well as the fetal one-minute Apgar score between different maternal ASA grade and gestational week.Results There were 98 cases of CS under GA enrolled in the study.Among the maternal and fetal factors, pregnancy with internal and surgical diseases is the most common reason(59 cases, 60%) for applying GA, followed by placenta and fetal membrane abnormalities (38 cases, 39%) and pregnancy-specific disorders(36
