Venoarterial extracorporeal membrane oxygenation (VA ECMO) has been increasingly applied in patients with cardiogenic shock in recent years. Nevertheless, many patients cannot be successfully weaned from VA ECMO support and 1-year mortality remains high. A systematic approach could help to optimize clinical management in favor of weaning by identifying important factors in individual patients. Here, we provide an overview of pivotal factors that potentially prevent successful weaning of VA ECMO. We present this through a rigorous approach following the relatable acronym ABCDE, in order to facilitate widespread use in daily practice.

从静脉动脉体外膜肺氧合中脱机困难的 ABCDE 方法

近年来，静脉动脉体外膜肺氧合（VA ECMO）越来越多地应用于心源性休克患者。然而，许多患者无法成功脱离 VA ECMO 支持，并且 1 年死亡率仍然很高。通过识别个体患者的重要因素，系统化的方法可以帮助优化临床管理，有利于脱机。在这里，我们概述了可能阻碍 VA ECMO 成功脱机的关键因素。我们通过遵循相关首字母缩写词 ABCDE 的严格方法来呈现这一点，以促进在日常实践中的广泛使用。
