研究目的:

1. 主要目的:评估初始即联合小剂量低分子肝素抗凝是否能有效延长局部枸橼酸抗凝的人工肝体外循环寿命。 2. 次要目的:初步确定联合方案的安全性。  

Objectives of Study:

1. The primary objective: To evaluate whether the initial combination of low-dose low-molecular-weight heparin anticoagulation can effectively prolong the extracorporeal circulation life of artificial liver with regional citrate anticoagulation. 2. The secondary objective: To preliminarily determine the safety of the combined regimen.
