摘要 目的观察极低剂量[0.001~0.1μg/(kg.h)]纳洛酮在减少硬膜外芬太尼-布比卡因术后镇痛不良反应的同时是否不降低其镇痛效果和对应激反应的抑制作用。方法选择行硬膜外麻醉下手术患者60例,ASAⅠ~Ⅱ级,年龄35~57岁,体重46~72 kg,随机分成两组,C组(对照组):0.125%布比卡因+4μg/mL芬太尼,共120 mL,PCA设定:背景流量3 mL/h、PCA剂量2 mL、锁定时间15 min;N组(纳洛酮组):在对照组镇痛液配方基础上加入纳洛酮100μg,PCA设定与之相同。定时观察并记录两组不良反应的发生和镇痛效果。结果两组均取得了良好的镇痛效果。C组24 h VAS评分2.16±0.49,N组VAS评分2.09±0.57(P>0.05),两组术后血糖、胰岛素较术前均有轻微升高(P<0.05),两组间差异无显著性。肠蠕动恢复时间:C组(28.7±4.2)h,N组(16.8±3.1)h(P<0.05),镇痛液总量:C组(92±4)mL,N组(81±3)mL(P<0.05)。结论芬太尼-布比卡因硬膜外镇痛时,辅助极低剂量[0.001~0.1μg/(kg.h)]的纳洛酮不仅可以保证镇痛效果和对应激反应的抑制作用,而且可以促进肠蠕动的恢复。
