胸椎旁神经阻滞在患儿围术期镇痛中的应用进展

胸椎旁神经阻滞（TPVB）是一种将局麻药注入胸椎旁间隙，从而节段性地阻滞单侧躯体感觉神经、运动神经及交感神经的区域阻滞技术。近年来，TPVB技术用于患儿胸部及上腹部手术麻醉与镇痛的研究不断增加，表现出良好的围术期镇痛效果。本文从TPVB用药方案、扩散途径、操作方法、临床应用及并发症等方面对TPVB技术用于患儿围术期镇痛的应用现状及研究进展进行综述。

Application progress on thoracic paravertebral nerve block in pediatric perioperative analgesia

Thoracic paravertebral nerve block (TPVB) is a regional anesthesia technique that provides ipsilateral somatosensory, motor and sympathetic nerves block segmentally by injecting local anesthetics in the paravertebral space. In recent years, there has been an increasing number of studies on the use of TPVB technique for anesthesia and analgesia in pediatric thoracic and upper abdominal surgery, showing good perioperative analgesic efficacy. This article intends to provide a review of the current application and progress of TPVB technique for pediatric perioperative analgesia in terms of medication regimens, drug diffusion routes, block methods, clinical application, and complications.
