摘要
目的:探讨双侧脑电双频指数用于缺血性脑血管病手术术中监测的意义。方法:分别选取颈动脉内膜剥脱术(CEA组)和椎管占位切除术(对照组)患者各十例,观察CEA组麻醉诱导前(T1)、阻断颈动脉前(T2)、颈动脉阻断时(T3)、开放颈动脉后(T4)四个时段5分钟内双侧BIS及平均动脉压(MAP)均值变化,以及对应时段对照组双侧BIS及MAP均值变化。结果:CEA组:T1时段,双侧BIS没有差异:T2时段4例手术侧BIS较对侧降低;T3时段5例手术侧BIS较对侧降低,MAP较T2时段升高;T4时段手术侧BIS均较T2时段升高,MAP较T3时段降低。1例阻断开放时双侧BIS降至40以下,手术侧降至28.6,术后MRI显示交界区有多发散在小梗塞灶。对照组:各时段双侧BIS及MAP比较无差异。结论:双侧脑电双频指数监测对缺血性脑病患者术中脑缺血有一定程度上的指导意义。
Objective： To study the value of bilateral bispecrral index （BIS） during operation with ischemic cerebrovascular disease. Methods：Ten patients undergoing carotid endarterectomy （CEA） and ten patients undergoing intraspinal tumors resection group （Matched Group） were enrolled.The bilateral BIS and MAP were monitored continuously in five minutes before anesthesia（T1）,before clamping carotid artery （T2）,after clamping carotid artery（T3） and after declamping carotid（T4）. Meanwhile the data of matched group was coliccted at the same time.Results：CEA group：The bilateral BIS value was not different at T1 .The BIS value of operation side was lewer than that on the opposite sido in four cases at T2 and in five cases at T3. The BIS value of operation side was higher than that at T2. The MAP at T3 was higher than that at T2. and was lower than that at T4. The BIS value was decreased below 40 at T3 and T4 in one case which was founded microirtfaret in junctional zone in MRI after operation. Matched group： There were no significanctly different in biiateral BIS, value and MAP.Conclusion： Bilateral BIS monitor can give us guidance when cerebral isehemia was occured during the operation with ischemic cerebrovascular disease.
