椎管内分娩镇痛的研究进展分析

Analysis of the Latest Research Progress on Intrathecal Labor Analgesia

摘要: 椎管内分娩镇痛作为目前公认的安全有效分娩镇痛方式，在近5~10年迎来技术优化、精准化用药的全方位突破。本文系统梳理该领域核心研究成果，聚焦技术革新(硬脊膜穿破硬膜外镇痛、程序化间歇硬膜外脉冲输注等)、药物配方优化、现争议的热点问题等关键方向，结合50余篇近年核心文献循证证据，综合分析椎管内麻醉分娩镇痛的临床转化成效与现存争议。研究表明，精细化技术改良、个体化药物配比及多学科管理模式显著提升了镇痛效果与母婴安全性，政策推动与服务体系完善加速了技术普及，但硬膜外相关发热机制、长期安全性等问题仍需深入探索。本文为临床实践提供循证参考，助力分娩镇痛向更安全、舒适、精准的方向发展。

Abstract: Epidural analgesia for labor, recognized today as a safe and effective method of pain relief during childbirth, has seen comprehensive breakthroughs in technological optimization and precise drug administration over the past 5~10 years. This article systematically reviews the core research achievements in this field, focusing on key areas such as technological innovations (e.g., combined spinal-epidural analgesia, programmed intermittent epidural bolus), drug formulation optimization, and current controversial issues. Drawing on evidence from over 50 recent key publications, it provides a comprehensive analysis of the clinical translation outcomes and existing disputes in neuraxial labor analgesia. Studies indicate that refined technical improvements, individualized drug regimens, and multidisciplinary management models significantly enhance analgesic efficacy and maternal and neonatal safety, while policy promotion and service system improvements have accelerated technology adoption. However, issues such as the mechanisms of epidural-related fever and long-term safety still require further investigation. This article offers evidence-based guidance for clinical practice and supports the development of labor analgesia toward a safer, more comfortable, and precise approach.
