Abstract:
Among 13 331 parturients from January 2011 to December 2013 in Peking University First Hospital, 6 162 cases required cesarean section, and the rate of cesarean section was 46.223％.The constituent ratio of cesarean section under general anesthesia was 1.75％, the constituent ratio of emergency cesarean section under general anesthesia was 60.2％, and the constituent ratio of the critically ill patients of ASA physical status ≥ Ⅲ was 16.7％.The main indication for general anesthesia was contraindication to neuraxial anesthesia or failure of neuraxial anesthesia.Of the 108 parturients who underwent cesarean section under general anesthesia, 33 cases were in laryngeal mask airway (LMA) group and 75 cases in intubation group.There was no statistically significant difference between intubation group and LMA group in terms of general data, emergency rate, percentage of patients or neonates admitted to intensive care unit, and neonatal Apgar score (P＞0.05).There were no airway-related complications such as difficult airway, aspiration or regurgitation in either group.In summary, general anesthesia was mainly suitable for cesarean section contraindicating neuraxial anesthesia and failed cesarean section, and the proportion of emergency operations was higher;LMA could be used for airway management in cesarean section under general anesthesia, but it must be placed correctly ensuring good airway sealing to prevent aspiration.
