ABSTRACT
Objective To investigate the influence on patients' coagulation of different anticoagulants during the treatment of severe hepatitis with ALSS (artificial liver support system).Methods According to different means of medication,20 severe hepatitis patients were divided into two groups randomly:heparin group,LMWH (low-molecular-weight heparin) group,and the two groups were provided with ALSS.The coagulation changes were evaluated before and after the treatment in two groups individually.Results There was no significant difference in hemoglobin levels before and after treatment in two groups.Prothrombin time (PT) and activated partial thromboplastin time (APTT) prolonged significantly before treatment,but returned to normal after treatment in heparin group;the two values were significantly lowered after treatment in LMWH group.There were increased fibrinogen level,thrombin time (TT) and decreased factor Ⅷ levels in both heparin and LMWH group.Many complications,such as blood pressure lowering,might occur in heparin group,but not in LMWH group.Conclusion It is effective and safe to use LMWH for severe hepatitis patients when treating with ALSS.
