0.1%罗哌卡因联合舒芬太尼在分娩镇痛中的应用

目的探讨低浓度罗哌卡因伍用舒芬太尼用于硬膜外分娩镇痛的效果浓度。方法100例同意接受硬膜外镇痛的足月初产妇，随机分为两组，每组50例。第一、二产程所有产妇均于硬膜外腔持续输注镇痛药。RS组（研究组）所用镇痛药物配方为：0．1％罗哌卡因，内含0．0002％舒芬太尼；R组（对比组）所用镇痛药物配方为单纯0．2％罗哌卡因。结果在第一产程中，RS组完全无疼痛者（58％）明显较R组多（32％）（P（0．01）；RS组产妇中出现轻度运动阻滞者（74％）明显比R组（32％）多（P〈0．01），而中度运动阻滞者（22％）明显少于R组（62％）（P〈0．01），两组间比较差异有显著意义。结论第一、二产程于硬膜外腔持续输注0．1％罗哌卡因＋0．0002％舒芬太尼，镇痛效果优于单纯0．2％罗哌卡因；对运动神经的阻滞发生率低于后者，阻滞程度也较轻，是一种较理想的分娩镇痛方法。

Clinical effect observation of ropivacaine with sufentanil matching to labor analgesia

Objective To explore analgesic effect of Ropivacaine with sufentanil combined to labor. Methods 100 full-term primipara randomized divided into two groups. During the first and second stage of labor, epidural ropivacaine 0.1% with sufentanil 0.000 2% was administered in group RS (n=50) and ropivacaine 0.2% in group R (n=50). Results The group RS painless labor rate was 58%, group R 32% in the first stage of labor (P<0.01). A significantly higher percentage of parturients in group RS had light motor block than in group R (P<0. 01), while Group R showed that a significantly higher incidence of moderate motor block compared with group RS (P<0. 01). Conclusion It is a suitable choice for analgesia with 0. 1% epidural ropivacaine combined 0. 00 2% sufentanil during labors.
