Serial prothrombin time as prognostic indicator in paracetamol induced fulminant hepatic failure.

Abstract

These data indicate that a continued increase in prothrombin time on day 4 after overdose and a peak prothrombin time of greater than or equal to 180 seconds identify at an early stage those patients with a less than 8% chance of survival. Liver transplantation should be considered in patients meeting either of these criteria.
