【摘要】 目的探讨腰麻-硬膜外联合阻滞(CSEA)用于分娩镇痛的效果及对产程、母婴的影响。方法观察组(n=50)在蛛网膜下腔隙注入布比卡因2mg和芬太尼20μg;然后PCEA用0.125%布比卡因+芬太尼2μg/ml,注药10ml/h。用视觉模拟评分(VAS)和下肢运动神经阻滞评分(MBS)评估镇痛、阻滞效果。结果麻醉后15min观察组产妇VAS、MBS镇痛前后相比有显著差异P<0.01。观察组活跃期时间短于对照组(P<0.01)。观察组第二产程时间与对照组无显著性差异(P>0.05)。结论CSEA用于分娩镇痛较硬膜外麻醉对运动神经阻滞轻,不影响产程及新生儿。更多还原

【Abstract】 Objective To explore the effect of CSEA and epidural anesthesia in labor painkilling, and its influence on delivery course and mother and infant. Methods Observation group (n=50)was injected Bubicane 2mg and Phentynil 20μg,after turning and lie horizontally, given 0.125%Ropinecane and 2μg/ml Phentynil epidurally and conduct PCEA, infusion speed 10ml/h;Control group(n=50) was given regular epidural puncture ,after turning and lie horizontally, given 0.25%bubicane 10ml epidurally, then PCEA with 0.125 Bubicane + Phentynil 2μg/ml ,infusion speed 10ml/h. the effect of painkilling and blocking was evaluated by VAS and MBS .Results The vital sign of observation group was stable, 99.2%parturant feel no pain 3~15min after medication [VAS score(0.04±0.11)]. 15min after anesthesia there is obvious difference in aspect of MBS of parturants between observation group and control group,P<0.01。The active time of observation group is (96.34±62.77)min, shorter than that of control group (P<0.01).The second delivery course time of observation group is (53.15±25.70)min, that of control group is (50.83±24.81)min,(P>0.05).Conclusion CSEA has less blocking on sport nerve than epidural anesthesia,sure effect and no influence on delivery course and neonate.更多还原
