椎管内分娩镇痛期间产时发热的机制及其防治研究进展

Research progress on the mechanism and prevention of intrapartum maternal fever during neuraxial labor analgesia

椎管内分娩镇痛技术的普及极大地减轻了产妇分娩时的剧烈疼痛, 但也带来了一些可能与椎管内分娩镇痛相关的问题, 如产时发热等。文章介绍了椎管内分娩镇痛期间产时发热高危因素, 如分娩镇痛的方式, 镇痛时长, 麻醉药物种类及剂量, 硬膜外药物注射的方式、方法, 胎膜早破, 阴道指检次数, 产程延长, 膜绒毛膜炎, 产妇BMI等, 就产时发热对产妇和新生儿的影响及相关的防治措施进行综述, 旨在为椎管内分娩镇痛产时发热的防治与研究提供一定的理论依据。

Neuraxial labor analgesia can greatly relieve severe pain during labor,but also cause related problems,such as fe⁃ver during labor.This paper introduces the high risk factors of intrapartum maternal fever during neuraxial labor analgesia,such as la⁃bor analgesia mode,analgesia duration,the types and doses of anesthetics,the methods of epidural drug injection,premature rupture of membranes,the time of vaginal examination,labor prolongation,histological chorioamnionitis,and maternal body mass index.We also reviews the effects of intrapartum fever on puerpera and neonates and related measures,so as to provide theoretical evidence for better prevention and treatment.
