BACKGROUND Awareness with recall under general anesthesia remains a rare but important issue that warrants further study. METHODS We present a series of seven cases of awareness that were identified from provider-reported adverse event data from the electronic anesthesia records of 647,000 general anesthetics. RESULTS The low number of identified cases suggests an under-reporting bias. Themes that emerge from this small series can serve as important reminders to anesthesia providers to ensure delivery of an adequate anesthetic for each patient. Commonalities between a majority of our identified anesthetic awareness cases include: obesity, use of total intravenous anesthesia, use of neuromuscular blockade, and either a lack of processed electroencephalogram (EEG) monitoring or documented high depth of consciousness index values. An interesting phenomenon was observed in one case, where adequately-dosed anesthesia was delivered without technical issue, processed EEG monitoring was employed, and the index value suggested an adequate depth of consciousness throughout the case. CONCLUSIONS Provider-reported adverse event data in the immediate post-operative period are likely insensitive for detecting cases of intraoperative awareness. Though causation cannot firmly be established from our data, themes identified in this series of cases of awareness with recall under general anesthesia provide important reminders for anesthesia providers to maintain vigilance in monitoring depth and dose of anesthesia, particularly with total intravenous anesthesia.

回顾性分析术后早期早期在大型多院卫生系统中的术中意识病例。

背景技术全身麻醉下的召回意识仍然是一个罕见但重要的问题,值得进一步研究。方法我们提供了一系列的7例意识清醒病例,这些病例是根据647,000例全身麻醉剂的电子麻醉记录中提供者报告的不良事件数据确定的。结果发现的病例数量少,表明报告不足。这个小系列的主题可以为麻醉提供者提供重要提示,以确保为每位患者提供足够的麻醉剂。我们确定的大多数麻醉意识病例之间的共同点包括:肥胖,使用全身静脉麻醉,使用神经肌肉阻滞剂,以及缺乏经过监测的脑电图(EEG)监测或已记录的高意识指数值。在一个病例中观察到一个有趣的现象,即在没有技术问题的情况下进行了适当剂量的麻醉,采用了经过处理的脑电图监测,并且指数值表明整个病例都具有足够的意识深度。结论手术后即刻提供者报告的不良事件数据对于检测术中知晓病例可能不敏感。尽管无法从我们的数据中明确确定因果关系,但是在这一系列全麻情况下可引起记忆的认识病例中,确定的主题为麻醉提供者保持警惕,以保持对麻醉深度和剂量的监测保持警惕,尤其是在全静脉麻醉下。使用了经过处理的脑电图监测,并且该指标值表明整个病例均具有足够的意识深度。结论手术后即刻提供者报告的不良事件数据对于检测术中知晓病例可能不敏感。尽管无法从我们的数据中明确确定因果关系,但在这一系列全麻情况下可引起记忆的认识病例中,确定的主题为麻醉提供者保持警惕,以保持对麻醉深度和剂量的监测保持警惕,特别是在全静脉麻醉下。使用了经过处理的脑电图监测,并且该指标值表明整个病例均具有足够的意识深度。结论手术后即刻提供者报告的不良事件数据对于检测术中知晓病例可能不敏感。尽管无法从我们的数据中明确确定因果关系,但是在这一系列全麻情况下可引起记忆的认识病例中,确定的主题为麻醉提供者保持警惕,以保持对麻醉深度和剂量的监测保持警惕,尤其是在全静脉麻醉下。结论手术后即刻提供者报告的不良事件数据对于检测术中知晓病例可能不敏感。尽管无法从我们的数据中明确确定因果关系,但是在这一系列全麻情况下可引起记忆的认识病例中,确定的主题为麻醉提供者保持警惕,以保持对麻醉深度和剂量的监测保持警惕,尤其是在全静脉麻醉下。结论手术后即刻提供者报告的不良事件数据对于检测术中知晓病例可能不敏感。尽管无法从我们的数据中明确确定因果关系,但是在这一系列全麻情况下可引起记忆的认识病例中,确定的主题为麻醉提供者保持警惕,以保持对麻醉深度和剂量的监测保持警惕,尤其是在全静脉麻醉下。
