Abstract/OtherAbstract:
|
Patients with liver disease frequently have substantial changes in their haemostatic system. This is reflected in abnormal test results on routine coagulation screening assays such as the prothrombin time (PT), activated thromboplastin time (APTT) and platelet count. Traditionally, attempts were made to correct abnormalities in the haemostatic system as measured by routine coagulation assays prior to invasive procedures by infusion of platelets or fresh frozen plasma (FFP). Recent laboratory and clinical data have indicated that the haemostatic reserve in cirrhotic patients is relatively well maintained although the coagulation screening assays suggest otherwise. Pre-procedural correction of coagulation tests with blood products may therefore not be necessary, and may even have harmful side-effects. In particular, fluid overload resulting in exacerbation of portal hypertension by infusion of blood products may in fact promote bleeding. In recent years, it has become clear that reduction of the central and portal venous pressure by fluid restriction and avoidance of blood product transfusion is a beneficial strategy in minimizing bleeding during liver surgery in cirrhotic patients. Some investigators have even taken this a step further and suggested pre-procedural phlebotomy in liver transplant recipients. The aim of this review is to provide an overview of recent studies and developments which have changed our understanding of the clinical relevance of abnormal coagulation tests in patients with cirrhosis, and which have contributed to a reduction in blood loss and transfusion requirements when liver surgery is needed in these patients. |
