麻醉药对脑电双频谱指数、听觉诱发电位指数判读影响及临床意义

Influence and clinical significance of anesthetic effect on the BIS and AAI

在临床麻醉中，维持合适的麻醉深度是保证患者安全，减少麻醉并发症的前提。脑电双频谱指数（bispectrial index，BIS）和听觉诱发电位指数（a—line aRX index，AAI）是近年来发展较好的意识水平监测手段，二者的工作原理不同，麻醉药对各自数值的判读影响也不尽一致，值得麻醉医生注意。现就相关问题作一综述。

In clinical anesthesia, maintaining a suitable anesthesia depth is the premise of guaranteeing the patient＇s safety and reducing anesthesia eomplieations. Bispeetral index and A-line ARX Index are better means to monitor the consciousness level developed in recent years. The mechanism is different from each other and the influence of anesthetic also does not exert consistently, which deserves our attention.
