全身麻醉期间的知晓和回忆研究进展

Research progress on awareness and recall during general anesthesia

术中知晓指患者在经历全身麻醉的手术过程中存在意识且术后可以回忆起术中发生的相关事件。患者经历术中知晓可能发展为严重的创伤后应激功能障碍,不应该被忽视。为了监测这种现象,新的研究已经进行。然而,包括基于脑电图仪技术去监测和预防术中知晓的测试方法的可信度都不高。术中缺乏统一标准的脑电监测给医务人员察觉术中知晓带来了困扰,如何预防术中知晓还需要继续探索。

Intraoperative awareness refers to the presence of consciousness in patients undergoing general anesthesia during surgery and patients recalling related events after surgery. Patients experiencing intraoperative awareness may develop severe post-traumatic stress disorder, which should not be overlooked. To monitor this phenomenon, new research has been performed. However, current techniques for monitoring and preventing intraoperative awareness, including those based on electroencephalogram(EEG), are of low credibility. As the absence of a unified standard for intraoperative EEG monitoring brings difficulties for medical works to detect intraoperative awareness, how to prevent intraoperative awareness remains a problem needed to be further explored.
