Acute deterioration of patients with cirrhosis manifests as multiple organ failure requiring admission to an intensive care unit. Precipitating events may be viral hepatitis, typically in Asia, and drug or alcoholic hepatitis and variceal hemorrhage in the West. Patients with cirrhosis in the intensive care unit have a high mortality, and each admission is associated with a mean charge of US $116,200. Prognosis is determined by the number of organs failing (sequential organ failure assessment [SOFA] score), the presence of infection, and the degree of liver dysfunction (Child-Turcotte-Pugh or Model for End-Stage Liver Disease scores). The most common organ failing is the kidney; sepsis is associated with further deterioration in liver function by compromise of the microcirculation. Care of these critically ill patients with impending multiple organ failure requires a team approach with expertise in both hepatology and critical care. Treatment is aimed at preventing further deterioration in liver function, reversing precipitating factors, and supporting failing organs. Liver transplantation is required in selected patients to improve survival and quality of life. Treatment is futile in some patients, but it is difficult to identify these patients a priori. Artificial and bioartificial liver support systems have thus far not demonstrated significant survival benefit in these patients.
肝硬化患者的病情急剧恶化表现为需要入住重症监护病房的多器官衰竭。诱发事件可能是病毒性肝炎,主要在亚洲,以及药物或酒精性肝炎和西方的静脉曲张出血。重症监护病房的肝硬化患者死亡率很高,每次住院的平均费用为 116200 美元。预后由衰竭器官的数量(序贯器官衰竭评估 [SOFA] 评分)、感染的存在以及肝功能障碍的程度(Child-Turcotte-Pugh 或终末期肝病模型评分)决定。最常见的衰竭器官是肾脏;脓毒症通过微循环受损导致肝功能进一步恶化。对这些即将发生多器官衰竭的危重患者的护理需要由肝病学和重症监护方面的专家组成的团队来进行。治疗旨在防止肝功能进一步恶化,逆转诱发因素,并支持衰竭的器官。在某些患者中需要进行肝移植以提高生存率和生活质量。在某些患者中治疗是无效的,但很难事先识别这些患者。人工和生物人工肝脏支持系统在这些患者中尚未显示出显著的生存获益。
