摘要 目的观察沙滩椅体位对老年高血压肩关节镜手术患者麻醉深度和血流动力学的影响。方法选择30例年龄65~75岁的老年高血压患者,采用肩关节镜手术修复肩袖损伤,术前规律服用药物治疗并控制血压在130/80 mm Hg以下。患者进入手术室后行静脉全麻,记录插管后5 min(T_1)、10 min(T_2)的脑电双频指数(BIS)、平均动脉压(MAP)、心率(HR)。将患者变动至沙滩椅体位,观察记录变动体位后即刻(T_3)、5 min(T_4)、10 min(T_5)的BIS、MAP、HR。观察并记录变动体位前后时间段内出现的心血管不良事件。结果患者由平卧位变换到沙滩椅体位后,T3、T4、T5时点MAP、HR、BIS与T_1、T_2时点相比明显降低(P均<0.05)。Pearnson相关性分析显示,本组患者MAP和BIS呈正相关(r=0.692,P<0.01);多元回归分析结果显示,本组患者MAP和BIS有关,r^2=0.452。体位变动后11例患者出现低血压,使用血管活性药物后纠正至正常范围。结论老年高血压患者肩关节镜手术前静脉全麻状态下由平卧位变至沙滩椅体位时,患者BIS、MAP和HR明显降低。
