全身麻醉的苏醒关系到患者的术后结局。然而,全身麻醉后的苏醒机制尚未完全阐明,这不利于降低麻醉并发症。研究表明,与睡眠觉醒相关的脑区参与了吸入麻醉的苏醒机制。腹侧被盖区(ventral tegmental area,VTA)作为中脑的关键结构,在大脑多种重要生理功能中扮演着不可或缺的角色。近年来,研究表明VTA在吸入麻醉苏醒作用机制中扮演重要作用。然而,不同吸入麻醉药物对VTA神经元的影响差异尚不明确,VTA与其他脑区在不同麻醉状态下神经环路的交互机制也有待进一步探究。因此,本综述主要对VTA的结构和功能,VTA参与吸入麻醉或静脉麻醉药物苏醒的机制做一简要综述。
Emergence from general anesthesia is critical to patients’ postoperative outcomes. However,the mechanisms underlying the emergence process have not been fully elucidated,which is not conducive to reducing anesthesia-related complications. Studies have shown that brain regions associated with sleep and wakefulness are involved in the mechanisms of recovering from inhalational anesthesia. The ventral tegmental area(VTA),which is a key structure of the midbrain,plays an indispensable role in various important physiological functions of the brain. Recent research has indicated that the VTA is critically involved in the mechanisms of emergence from inhalational anesthesia. However,the differences in the effects of different inhalational anesthetics on VTA neurons remain unclear,and the interactive mechanisms of neural circuits between the VTA and other brain regions under different anesthetic states need to be further explored. Therefore,this review mainly focuses on the structure and function of the VTA as well as the mechanisms by which the VTA mediates emergence from inhalational or intravenous anesthetic drugs.
