摘要
目的调查全身麻醉下行择期或限期手术病人的术中知晓发生率,分析可能引起术中知晓的原因。方法随机选择接受全身麻醉的择期或限期手术病人500例,于术后1d及4d对病人是否存在术中知晓行问卷调查,对存在术中知晓的病人记录感知觉,采用多元回归分析可能影响术中知晓的因素。结果共10例(2.0%)病人存在术中知晓,其中1例病人对手术过程有明确的描述,另9例患者仅述及手术期间做梦,无痛觉及其他感知觉。而病人的性别、年龄、体重、ASA分级、麻醉前用药、麻醉方法、手术时间、手术类型、术中循环状态对术中知晓的发生无显著影响。结论术中知晓在多种类型手术中均有发生,无确切的因素可影响术中知晓的发生。
Objective To investigate the incidence of awareness during general anesthesia in selective or limited operation and analyze the risk factors of awareness in operation.Methods A total of 500 patients underwent general anesthesia during different kinds of selective or limited operation were surveyed by questionnaire on the first day and fourth day after operation,and the incidence of awareness during operation was counted.The sensory perception was recorded in patients having awareness in operation.The factors that probably influenced awareness were analyzed with the method of multiple regression analysis.Results Ten patients （2.0%） were identified as with awareness. One patient could definitely describe the process of operation,and other nine patients could only talk about dreaming during operation without sense of pain or other sensory perception.The sex,age,weight,class of ASA,preanesthetic medication,anesthetic method,operation time,operation type and circulating state of the patients did not relate with awareness （all P〉0.05）. Conclusions Awareness could take place in every type of operation.No definite factor could lead to awareness.
