成人体外膜肺氧合患者的营养支持

Nutrition support for adult patients undergoing extracorporeal membrane oxygenation

体外膜肺氧合技术（ECMO）是近年来用于严重心脏衰竭或呼吸衰竭患者的新兴治疗技术。这些重症患者往往处于分解代谢增加，蛋白质分解代谢增强以及能量负债积累的状态，且因多种原因难以达到营养支持目标，因此是营养支持一个必须面对的难题。目前尚无ECMO患者的营养支持指南，本文主要针对目前成人ECMO期间营养支持的现状及注意事项进行综述。

Extracorporeal membrane oxygenation （ECMO） is a novel mechanical system that provides respiratory and/or hemodynamic support to patients with severe respiratory or cardiac failure. These patients generally develop a state of increased metabolic activity accompanied by elevated catabolism of protein and negative nitrogen balance. Moreover, provision of adequate nutritional therapy is hard to achieve due to various factors. Nutrition support for these patients is hence a critical issue. This article provides a brief overview of the current literature regarding nutritional support during ECMO in adult patients, as no current guidelines address this issue.
