营养支持是重症患者综合救治措施中不可或缺的重要组成部分，首选肠内营养已成为临床共识。多项指南推荐，对于胃内喂养不耐受或存在反流、误吸高风险的重症患者应启动幽门后喂养。而幽门后喂养路径的建立是启动幽门后喂养的前提，在ICU常通过床旁放置鼻肠管至十二指肠或空肠以达此目的。目前存在多种重症患者鼻肠管幽门后置管方法，但尚无统一标准。为此，笔者所在团队开展了幽门后置管系列研究，积累了较多量的螺旋型鼻肠管幽门后置管经验，对幽门后置管技术作了一定的优化，特在此做一总结，供同行参考。

Nutritional support is an indispensable part of comprehensive treatment for critically ill patients. It is the clinical consensus that enteral nutrition is the first choice in critically ill patients. Numerous guidelines recommend that post-pyloric feeding should be initiated in critically ill patients who are high risk for aspiration or intolerant of intragastric feeding. The establishment of a post-pyloric feeding tube is the precondition for post-pyloric feeding. Post-pyloric feeding access to the duodenum or jejunum is usually attempted by the bedside placement of a nasoenteric tube in intensive care units. There are various methods for post-pyloric placement of nasoenteric tubes in critically ill patients, but there is no uniform standard. Therefore, our team has carried out a series of studies on post-pyloric placement, accumulated a large amount of experience on post-pyloric spiral nasoenteric tube placement, and made specific optimizations on the post-pyloric placement technology. We summarize our experience here to provide some suggestions.
