听觉诱发电位与双频谱指数监测地氟醚麻醉后苏醒的比较

Compare MLAEP and BIS in predicting recovery time at the end of desflurane anesthesia

目的 比较中潜伏期听觉诱发电位 (MLAEP)与双频谱指数 (BIS)在预计地氟醚麻醉后苏醒的作用。方法 30例择期全麻腹部手术病人 ,诱导后地氟醚维持麻醉 ,麻醉停药前 3min记录MLAEP和BIS ,观察麻醉停药后命令反应时间、拔管时间及达到修正Aldrete计分 (MAS)≥ 9时间。结果 MLAEP的Nb潜伏期和BIS与苏醒各指标相关 ,但Nb潜伏期能更确切反映地氟醚麻醉后苏醒。

Objective To compare the reliability of midiatency auditory evoked potentials (MLAEP) and bispectral index(BIS) in predicting the recovery time after desflurane anesthesia.Methods Thirty patients undergoing elective general anethesia abdominal operation were ned with desflurane maintains after induction. The MLAEP and BIS were recorded during 3min interval before the discontinuation of desflurane.Commander reflect time,extubation time and the time to reach modified aldrete score≥9 were observed from the end of anesthesia.Results The Nb latency of the MLAEP and BIS were correlated well with all parameters of the recovery time.But the Nb latency was more exactly in predicting the recovery time at the end of desflurane anesthesia.Conclusion The Nb latency of the MLAEP at the end of anesthesia is credible parameter in predicting recovery time with desflurane anesthesia.
