脑电双频指数监测在全身麻醉术后患者转出术后恢复室时的安全性评估

目的 探讨脑电双频指数(BIS)监测在全身麻醉术后患者转出术后恢复室(PAICU)时的指导意义.方法 选取除神经外科手术的全身麻醉患者75例,测定患者转出PAICU时的BIS.结果 21例BIS为90～100;48例BIS为80～89,处于轻度镇静催眠;5例BIS为70～79;1例BIS为50～60.结论 在无BIS监测下大部分全身麻醉患者转出PAICU时均处于轻度镇静状态,较为安全.但仍有个别患者BIS较低,镇静过度,转回普通病房时存在一定的危险性.BIS监测为指导患者转出PAICU提供了良好的数据参考.

Significance of bispectral index monitoring during the patients after general anesthesia while leaving the post-anesthetic intensive care unit

Objective To discuss the significance ofbispectral index (BIS) monitoring during the patients after general anesthesia while leaving the post-anesthetic intensive care unit (PAICU). Methods Seventy-five cases after general anesthesia were selected. When they were sent out of the PAICU, recorded their BIS. Results Twenty-one cases with BIS 90 - 100,48 cases with BIS 80 - 89 in slight calm and hypnosis,5 cases with BIS 70 - 79, and 1 case with BIS 50 - 60. Conclusions Without BIS monitoring,when sent out of the PAICU,most patients after general anesthesia are gently sedated and without too much risk. But still some patients are deeply sedated. BIS monitoring provides a nice reference for the patients while leaving the PAICU.
