Abstract:

目的:探讨颅底手术中出现三叉-心反射(trigeminocardiac reflex, TCR)的形成机制、临床特征及相关预后。方法: 回顾性分析2009年1月至2015年10月北京大学第一医院神经外科291例颅底手术患者,通过复习相关的手术资料及麻醉记录,找出术中出现TCR的病例(在刺激或操作三叉神经相关区域时,出现与麻醉因素无关的平均动脉压突然下降和心率突然减慢并超过基线值的20%), 分析其手术方式、临床特征、影响因素及相应预后。结果: 291例颅底手术患者中,9例患者术中共出现TCR 19 次,包括神经鞘瘤4例(听神经瘤3例,三叉神经鞘瘤1例)、脑膜瘤1例、表皮样囊肿1例、海绵窦海绵状血管瘤1例、垂体瘤1例、三叉神经痛1例。TCR诱发方式均与三叉神经主干或其分支受操作、牵拉有关,操作前基线心率为62~119 /min,平均(79.4±14.6) /min,TCR发生时,心率为22~60 /min,平均(44.2±9.6) /min,心率下降比例为29.0%~66.4%,平均下降比例为44.3%。基线平均动脉压为75~103 mmHg,平均(87.5±7.8) mmHg,TCR发生时,平均动脉压为45~67 mmHg,平均为(54.9±6.3) mmHg,血压下降比例为23.4%~47.2%,平均下降比例为37.3%。TCR出现后,停止刺激或操作心率血压自行恢复者8例次,应用阿托品8例次,剂量0.5~1.0 mg,平均0.69 mg,应用盐酸麻黄碱1例次,应用肾上腺素1例次,应用多巴胺1例次,患者血压及心率均很快恢复至基线水平,重复刺激可再次诱发。术后24 h无TCR相关心血管并发症及神经功能障碍。结论: TCR是在颅底手术中由于对三叉神经或其分支操作刺激时出现的一种以心率变慢、血压降低为表现的神经反射,虽然其预后良好,但仍需正确判断、密切观察,必要时需给予处理。
