Patients with cirrhosis who are awaiting liver transplantation (LT) are at high risk for developing critical illnesses. Current liver allocation policies that dictate a "sickest first" approach coupled with a mismatch between need and availability of organs result in longer wait times, and thus, patients are becoming increasingly ill while awaiting organ transplantation. Even patients with well-compensated cirrhosis may suffer acute deterioration; the syndrome of acute-on-chronic liver failure (ACLF) results in multisystem organ dysfunction and a marked increase in associated short-term morbidity and mortality. For patients on transplant waiting lists, the development of multisystem organ failure may eliminate candidacy for transplant by virtue of being "too sick" to safely undergo transplantation surgery. The goals of intensive care management of patients suffering ACLF are to rapidly recognize and treat inciting events (eg, infection and bleeding) and to aggressively support failing organ systems to ensure that patients may successfully undergo LT. Management of the critically ill ACLF patient awaiting transplantation is best accomplished by multidisciplinary teams with expertise in critical care and transplant medicine. Such teams are well suited to address the needs of this unique patient population and to identify patients who may be too ill to proceed to transplantation surgery. The focus of this review is to identify the common complications of ACLF and to describe our approach management in critically ill patients awaiting LT in our centers.

等待肝移植 (LT) 的肝硬化患者患危重病的风险很高。目前的肝脏分配政策规定了“先病先治”的方法,加上器官需求与供应之间的不匹配,导致等待时间延长,因此,患者在等待器官移植时病情越来越严重。即使是代偿良好的肝硬化患者也可能会出现急性恶化;慢加急性肝衰竭 (ACLF) 综合征会导致多系统器官功能障碍,并显著增加相关短期发病率和死亡率。对于移植等待名单上的患者,多系统器官衰竭的发展可能会因“病情太重”而无法安全进行移植手术而丧失移植资格。ACLF 患者重症监护管理的目标是快速识别和治疗激发事件(例如感染和出血),并积极支持衰竭的器官系统,以确保患者可以成功进行 LT。由具有重症监护和移植医学专业知识的多学科团队来管理等待移植的危重症 ACLF 患者效果最佳。这些团队非常适合满足这一独特患者群体的需求,并确定可能因病情太重而无法进行移植手术的患者。本综述的重点是确定 ACLF 的常见并发症,并描述我们在中心对等待 LT 的危重症患者的管理方法。肝脏移植 23 1465-1476 2017 AASLD。
