The PENG block is a recently described ultrasound-guided technique for the blockade of the sensory nerve branches to the anterior hip joint capsule. It was described as an analgesic block for the acute pain management after hip fracture, while subsequent studies expanded the original indication. The aim of this narrative review was to summarize the existing knowledge about the PENG block from the anatomical bases and to provide an up-to-date description of the technique, applications and effects.
We reviewed the following medical literature databases for publications on PENG block: PubMed, Google Scholar, EMBASE, and Web of science until August 31st, 2020. Data regarding anatomy, indications, drugs and technique were also collected, reported and discussed.
From our search result we selected 57 relevant publications. Among them, 36 were case reports or case series and 12 publication were letters or correspondence; no RCT was identified. The main indication is the hip-related analgesia. The most commonly injected drug is a 20ml long-acting local anesthetic. There are some cases of femoral and obturator nerve block, but no major complication such as hematoma/bleeding or needle-related organ injury has been reported yet.
The PENG block is a promising technique. Randomized controlled trials of high methodological quality are required to further elaborate the role of this block.
PENG 阻滞是一种最近描述的超声引导技术，用于阻滞髋关节囊前支感觉神经分支。它被描述为髋关节骨折后急性疼痛管理的镇痛阻滞，随后的研究扩展了最初的适应证。本综述的目的是总结 PENG 阻滞的解剖基础和现有知识，并对该技术、应用和效果进行最新描述。
我们在 2020 年 8 月 31 日之前，在以下医学文献数据库中搜索了 PENG 阻滞的出版物：PubMed、Google Scholar、EMBASE 和 Web of Science。还收集、报告和讨论了关于解剖学、适应证、药物和技术的数据。
从我们的搜索结果中，我们选择了 57 篇相关出版物。其中，36 篇是病例报告或病例系列，12 篇是信件或通信；没有随机对照试验。主要适应证是与髋关节相关的镇痛。最常注射的药物是 20ml 长效局麻药。有一些股神经和闭孔神经阻滞的病例，但尚未报告任何主要并发症，如血肿/出血或与针相关的器官损伤。
PENG 阻滞是一种有前途的技术。需要高质量的随机对照试验来进一步阐明该阻滞的作用。
