MONITOR AND MODULATION OF COAGULATION DISORDER DURING THE OPERATION OF LIVER TRANSPLANTATION / 解放军医学杂志

ABSTRACT

Objective To monitor and modulate the coagulation disorder during operation in patients undergiong allogeneic liver transplantation. Methods PT, TT, APTT, FIB, HB, PLT count, sonoclot coagulation and platelet function were measured dynamically in 10 patients during anesthesia and operation. Results After coagulants were used, the above parameters pertaining to coagulation function were improved obviously. All of above coagulation parameters were severely abnormal in the period from 30 minutes before anesthesia to 20 minutes after portal vein recirculation. The hypocoagulability was significantly improved at the end of operation by target supplementation of prothrombin complex, fibrinogen, fresh platelets, and other coagulants, complementing large amount of fresh blood plasma. Notably, severe hemorrhage and thrombosis leading to re-operation did not happen in all the recepients. Conclusion The relationship of the local hypercoagubility at the anastomosis and the systemic hypocoagulation should be concerned to prevent coagulation and thrombosis during operation of liver transplantation.
