研究目的:

本研究旨在系统评估一种创新的“预置硬膜外导管”技术,其核心目的在于通过将分娩镇痛的实施时机从传统的“疼痛发生后”提前至“产程早期、疼痛发生前”,以解决现有临床实践中因产妇疼痛导致的操作配合度差、穿刺风险高以及镇痛延迟等问题。通过这项前瞻性随机对照研究,我们拟验证该技术在产妇安静状态下提前置管的可行性、安全性及其临床优效性,以期实现分娩疼痛的即时、快速缓解,最终达到全面提升产妇分娩镇痛的安全性与舒适性体验的根本目标。  

Objectives of Study:

This study aims to systematically evaluate an innovative "pre-set epidural catheter" technique. By shifting the timing of labor analgesia from the conventional "reactive" approach (after pain onset) to a "proactive" strategy (early labor, before pain occurs), we seek to address persistent clinical challenges: maternal non-cooperation due to pain, heightened procedural risks, and delayed analgesia. In this prospective randomized controlled trial, we will validate the feasibility, safety, and clinical efficacy of catheter insertion during the latent phase of labor when the parturient is calm and pain-free. Our ultimate goal is to enable immediate analgesia upon request and thereby improve both the safety profile and maternal satisfaction with labor pain management.
