研究目的:

本研究旨在对比连续硬膜外麻醉下两种不同药物方案在无痛分娩中的应用效果,通过评估无痛分娩率、疼痛评分、产妇主动追加药物次数及分娩时肌力情况等指标,旨在寻找更加合适的用药方案,提升镇痛效果与母婴安全性,为临床实践提供循证依据。  

Objectives of Study:

This study aims to compare the efficacy of two different drug regimens for painless labor under continuous epidural anesthesia by evaluating indicators such as the rate of painless labor, pain scores, the number of times parturients actively request additional medication, and maternal muscle strength during delivery. The goal is to identify a more suitable drug regimen to enhance analgesic effectiveness and maternal-fetal safety, thereby providing evidence-based support for clinical practice.
