Intraoperative awareness is defined by both consciousness and explicit memory of surgical events. Although electroencephalographic techniques to detect and prevent awareness are being investigated, no method has proven uniformly reliable. The lack of a standard intraoperative monitor for the brain likely reflects our insufficient understanding of consciousness and memory. In this review, the authors discuss the neurobiology of consciousness and memory, as well as the incidence, risk factors, sequelae, and prevention of intraoperative awareness.
术中意识是指对手术事件有意识和明确记忆。尽管正在研究脑电图技术来检测和预防意识，但没有一种方法被证明是完全可靠的。缺乏一种标准的脑内监测方法可能反映了我们对意识和记忆的理解不足。在这篇综述中，作者讨论了意识和记忆的神经生物学，以及术中意识的发生率、危险因素、后果和预防。
