The intraoperative awareness is an adverse event in the general anesthesia, and may occur in approximately 20,000 cases per year, which justifies the study of the risk factors for this event. The objective of this study was to review this subject in order to reduce the incidence of intraoperative awareness and psychological sequelae incurring from this incident, which may result in post-traumatic stress disorder with negative repercussions on the surgical patient social, psychic and functional development.
It was conducted a review of the intraoperative awareness assessing its different phases during general anesthesia such as dreaming, wakefulness, explicit and implicit memory, as well as the analysis, consequences and prevention of its main related factors.
The reduction of awareness incidence during anesthesia is related to the anesthesiologist improved scientific and technical performance, involving issues such as monitoring, comprehension of the anesthesia activity components, hypnotic and analgesic drugs, neuromuscular blocking agents, autonomic and motor reflex control, in addition to the risk factors involved in this event.
术中知晓是全身麻醉中的一种不良事件，每年约有20000例发生，这使得对该事件的危险因素进行研究成为必要。本研究的目的是回顾这一主题，以降低术中知晓的发生率以及由此引发的心理后遗症，这些后遗症可能导致创伤后应激障碍，对手术患者的社会、心理和功能发展产生负面影响。
对术中知晓进行了回顾，评估了其在全身麻醉期间的不同阶段，如梦、清醒、显性和隐性记忆，以及对其主要相关因素的分析、后果和预防。
麻醉期间知晓发生率的降低与麻醉医生科学技术水平的提高有关，这涉及到监测、对麻醉活动组成部分的理解、催眠和镇痛药、神经肌肉阻滞剂、自主神经和运动反射控制等问题，以及该事件所涉及的危险因素。
