To investigate the incidence of awareness during general anesthesia in patients undergoing surgery.
A total of 1,800 patients who underwent the selected and acute surgery with general anesthesia were enrolled. Brain function monitors were not used. Patients were interviewed twice during 24 h and 96 h postoperatively to determine intraoperative awareness.
Of all the inpatients, 13 (0.72%) reported clear awareness and never forgot anything during the operation; 145 (8.1%) reported dreaming during anesthesia with doubtful intraoperative recollection. Among the 145 patients, 108(74.5%) were females and 114(78.6%) received propofol anesthesia.
Intraoperative recollections are rare complication of general anesthesia, and are associated with the increased ASA physical status. Age and sex do not influence the incidence of awareness. Dreaming during anesthesia is related to younger females and propofol maintenance.
调查接受手术的患者在全身麻醉期间知晓的发生率。
共纳入1800例接受择期和急诊手术并接受全身麻醉的患者。未使用脑功能监测仪。术后24小时和96小时对患者进行两次访谈，以确定术中知晓情况。
在所有住院患者中,13例(0.72%)报告有清晰的知晓且术中未遗忘任何事情；145例(8.1%)报告在麻醉期间做梦且术中回忆可疑。在这145例患者中，108例(74.5%)为女性，114例(78.6%)接受丙泊酚麻醉。
术中回忆是全身麻醉罕见的并发症，且与美国麻醉医师协会(ASA)身体状况增加有关。年龄和性别不影响知晓的发生率。麻醉期间做梦与年轻女性和丙泊酚维持麻醉有关。
