研究目的:

本研究通过测定0.1%罗哌卡因复合0.5μg/mL舒芬太尼用于EP、DPE及DDPE三种麻醉方式时,能够使95%的产妇达到满意镇痛(VAS≤3分)的初始负荷剂量(ED95)及其95%置信区间。比较三种麻醉方式在分娩镇痛中的应用效果,包括镇痛起效时间、运动阻滞程度、产程进展、不良反应发生率、新生儿结局及产妇满意度,为临床选择提供循证依据。  

Objectives of Study:

This study determined the ED95 (the initial bolus dose effective in achieving satisfactory analgesia, defined as a visual analog scale [VAS] score ≤ 3, in 95% of parturients) and its 95% confidence interval for a solution containing 0.1% ropivacaine combined with 0.5 μg/mL sufentanil when administered via Epidural (EP), Dural Puncture Epidural (DPE), and Double Dural Puncture Epidural (DDPE) techniques. It compared the clinical outcomes of these three analgesic modalities for labor analgesia, including the onset time of analgesia, degree of motor blockade, progression of labor, incidence of adverse effects, neonatal outcomes, and maternal satisfaction. The aim is to provide an evidence-based foundation for clinical decision-making.
