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.

本文件为某综述的研究方案，无附带摘要。本综述的研究目标如下：评估两类麻醉干预手段在降低临床显著性术中知晓方面的有效性，分别为麻醉药物方案与术中麻醉深度监测仪（anaesthetic depth monitor, 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，包含以下亚类：
(2a) 吸入麻醉用于诱导与维持阶段；
(2b) 静脉诱导联合吸入麻醉维持（其中静脉诱导药物或维持用吸入麻醉剂可进行调整）；
3. 联用阿片类药物的吸入麻醉方案，与“纯”吸入麻醉技术进行对比；
4. 上述所有方案，分别联合或不联合肌肉松弛剂（muscle relaxant, MRs）；
5. 上述任一技术联合区域麻醉。
术中麻醉深度监测仪涵盖的类型包括：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。
