全身麻醉手术中知晓发生率的调查与分析

The investigation and analysis of the incidence of awareness in general anesthesia operation

目的对全身麻醉手术中知晓的发生情况进行调查与分析。方法选择2010年1月～2011年12月来我院择期予以手术的1856例患者为研究对象,均予以全身麻醉,记录术中知晓发生的详细情况,对其影响因素采用多因素Logistic回归分析。结果本组1856例患者共15例发生术中知晓,发生率为0.81%。术中知晓发生时期以维持期最多,占86.67%。不同科室中以妇科术中知晓发生率最高为2.03%,其次为耳鼻咽喉科为0.63%,再次为泌尿外科为0.54%。性别、年龄、是否使用阿片类镇痛剂、是否气管插管方式是影响术中知晓发生的危险因素,是否术前用药则是其保护因素。结论术中知晓好发于维持期,在多种择期手术者散发。为降低术中知晓的发生率应注意女性患者,术前应充分用药,避免使用阿片类镇痛剂、行气管插管。

Objective To investigate and analyse the incidence during general anesthesia operation. Methods Selected 1 856 patients in our hospital during Jan. 2010 to Dec. 2011 as the research object, making them general anesthesia, recording intraoperative awareness occurs in details, using multivariate Logistic regression to analyze its influence fac- tors. Results 15 cases of in this group were intraoperative awareness, occurred at a rate of 0.81%. Awareness during operation period maintains maximum, 86.67%. Gynecologic intraoperative awareness rate is the highest of 2.03%, t：ol- lowed by the Otolaryngology of 0.63%, then the Department of Urology of 0.54%. Gender, age, whether using opioid analgesics, whether using tracheal intubation is the risk factors on effect of intraoperative awareness, whether premedi- cation is the protective factor. Conclusion Intraoperative awareness occurred in the maintenance phase, in a variety of elective operation distributing. In order to reduce the incidence of intraoperative awareness, attention should be given to female patients, preoperative full use, and avoids the use of onioid ana/gesics, endotracheal intllhntian
