Bleeding related to portal hypertension and coagulopathy is a common complication in patients with cirrhosis. Complications and management of bleeding is a significant source of healthcare cost and utilization, as well as morbidity and mortality. Due to the scarcity of evidence surrounding transfusion strategies and hemostatic interventions in patients with cirrhosis, there has been significant debate regarding the best practice. Emerging data suggest that evidence supporting transfusion of packed red blood cells to a hemoglobin threshold of 7-8 g/dL is strong. thrombopoietin (TPO) receptor agonists have shown promise in increasing platelet levels and reducing transfusions preprocedurally, although have not specifically been found to reduce bleeding risk. Data for viscoelastic testing (VET)-guided transfusions appear favorable for reducing blood transfusion requirements prior to minor procedures and during orthotopic liver transplantation. Hemostatic agents such as recombinant factor VIIa, prothrombin complex concentrates, and tranexamic acid have been examined but their role in cirrhotic patients is unclear. Other areas of growing interest include balanced ratio and whole blood transfusion. In the following manuscript, we summarize the most up to date evidence for threshold-guided, VET-guided, balanced-ratio, and whole blood transfusions as well as the use of hemostatic agents in cirrhotic patients to provide practice guidance to clinicians.
与门静脉高压和凝血障碍相关的出血是肝硬化患者的常见并发症。出血的并发症和管理是医疗保健成本和利用、发病率和死亡率的重要来源。由于肝硬化患者的输血策略和止血干预措施的证据稀缺,因此围绕最佳实践存在很大争议。新出现的数据表明,支持将浓缩红细胞输注至血红蛋白阈值为 7-8 g/dL 的证据是强有力的。血小板生成素(TPO)受体激动剂已显示出在增加血小板水平和减少术前输血方面有希望,但尚未发现它们能降低出血风险。用于粘弹性检测(VET)指导输血的数据似乎有利于减少小手术前和原位肝移植期间的输血需求。重组凝血因子 VIIa、凝血酶原复合物浓缩物和氨甲环酸等止血剂已被研究,但它们在肝硬化患者中的作用尚不清楚。其他日益受到关注的领域包括平衡比例和全血输血。在下面的手稿中,我们总结了肝硬化患者阈值指导、VET 指导、平衡比例和全血输血以及止血剂使用的最新证据,为临床医生提供实践指导。
