目的研究右旋美托咪啶联合低浓度罗哌卡因腹横肌膜神经阻滞在老年患者阴式子宫切除术中应用的有效性及安全性。方法选择择期行阴式子宫切除术患者40例(ASA Ⅰ～Ⅱ级),随机分成两组,选择硬腰联合麻醉下手术,麻醉平面固定后以超声引导给予患者双侧腹横肌膜神经阻滞,Ⅰ组患者选用0.5 μg/kg右旋美托咪啶+0.2%罗哌卡因,每侧20 mL,Ⅱ组以相同方法给予同量生理盐水。记录麻醉前(T₀)、麻醉平面确定后(T₁)、手术开始(T₂)、牵拉子宫(T₃)、术毕(T₄)患者的HR、MAP、SpO₂及NTI评分;评价并记录牵拉反应、术后认知功能障碍及谵妄的发生及患者舒适度及满意度。结果两组患者一般情况无显著性差异(P>0.05);与I组相比,Ⅱ组HR在T₃时刻有显著性降低,差异有统计学意义(P<0.05),牵拉反应评价Ⅰ组评为优的患者个数明显多于Ⅱ组,差异有统计学意义(P<0.05);Ⅰ组舒适度及满意度评定为优的患者个数明显多于Ⅱ组,差异有统计学意义(P<0.05)。结论右旋美托咪啶联合低浓度罗哌卡因腹横肌膜神经阻滞在老年患者阴式子宫切除术中应用是安全有效的。
