Data from: Anaesthetic interventions for prevention of awareness during surgery

This is the protocol for a review and there is no abstract. The objectives are as follows: The objective of this review is to evaluate the efficacy of two types of anaesthetic interventions on reducing clinically significant awareness: anaesthetic drug regimens; and intraoperative anaesthetic depth monitors (ADM). Categories of anaesthetic drug regimens include: (1) intravenous (IV); (2) pure inhalational, including the following subgroups: (2a) inhalation used for induction and maintenance, (2b) IV induction and inhalational maintenance, where the IV induction or inhalational agent for maintenance are varied; (3) inhalational with narcotics as compared to a 'pure' inhalational technique; (4) all of the above regimens with and without muscle relaxants (MRs); (5) any of these previous techniques with regional anaesthesia. ADMs include: Bispectral index (BIS) monitor, Narcotrend monitor, cerebral function monitor, cerebral state monitor, patient state index, and lower oesophageal contractility monitor.本文件为某系统综述的研究方案，暂未附摘要。本综述的研究目标如下：本系统综述旨在评估两类麻醉干预措施在降低临床显著性知晓方面的有效性：麻醉药物方案，以及术中麻醉深度监测仪（intraoperative anaesthetic depth monitors, ADM）。麻醉药物方案的类别包括：(1) 静脉（intravenous, IV）麻醉方案；(2) 纯吸入麻醉方案，包含以下亚组：(2a) 吸入麻醉用于诱导与维持，(2b) 静脉诱导联合吸入维持，且诱导所用静脉麻醉药或维持所用吸入麻醉药可按需调整；(3) 阿片类药物联合吸入麻醉与‘纯’吸入麻醉技术的对比方案；(4) 上述所有方案联合或不联合肌肉松弛剂（muscle relaxants, MRs）；(5) 前述任一技术联合区域麻醉。术中麻醉深度监测仪（ADM）包括：脑电双频指数（Bispectral index, BIS）监测仪、Narcotrend监测仪、脑功能监测仪、脑状态监测仪、患者状态指数监测仪以及食管下段收缩力监测仪。
