摘要 目的探讨超声引导硬膜外穿刺在极重度肥胖产妇剖宫产应用的可行性和应用前景。方法选择拟行择期剖宫产的极肥胖产妇60例,随机分为两组(每组30例):对照组采用对L2~3椎间隙传统体表标志定位,盲探进行硬膜外穿刺,依靠突破感和阻力消失感确认穿刺成功;观察组采用超声定位穿刺点并引导硬膜外穿刺置管。记录两组穿刺时间,穿刺次数,一次穿刺成功率及麻醉效果,麻醉中不良反应及麻醉后并发症,测量超声预测穿刺深度及实际穿刺深度;并记录患者对整个硬膜外穿刺的满意度评分。结果 2组患者麻醉穿刺均成功,麻醉效果均能满足手术需求;与对照组相比,超声组穿刺时间明显缩短(P<0.05),一次穿刺成功率明显提高(P<0.05);三次穿刺以上次数明显低于对照组(P<0.05);超声组穿刺或置管异感出现率与术后腰痛发生率降低(P<0.05);患者对超声组硬膜外穿刺满意度明显高于对照组(P<0.05)。结论超声引导硬膜外穿刺能缩短极肥胖产妇硬膜外穿刺时间,减少穿刺次数和麻醉并发症,提高麻醉质量,值得在临床上推广应用。
