Coagulation and biochemical effects of balanced salt-based high molecular weight vs saline-based low molecular weight hydroxyethyl starch solutions during the anhepatic period of liver transplantation.
Anaesthesia. 2008 Mar; 63(3):235-42.A

Abstract

The anhepatic period of liver transplantation is generally marked by a decrease in preload, and the infusion of hydroxyethyl starch (HES) solution is often an effective way to restore volume deficits in non-anaemic patients. However, the infusion of even limited amounts of HES solution during the anhepatic period may result in a worsening coagulopathy. Moreover, lactate-containing HES solution may cause some degree of biochemical derangements in compromised recipients. Therefore, we compared two different types of HES solutions: a balanced salt-based high molecular weight HES solution (670/0.75; high MW group) and a saline-based low molecular weight HES solution (130/0.4; low MW group) with respect to coagulation and biochemical profiles. First, in an in vitro study (n = 48), thromboelastography was performed to determine the effects of two HES solutions on coagulation after diluting (11%) the recipient's blood sample with each HES solution. Second, in an in vivo study, 500 ml of one of the two 6% HES solution was administered to 74 recipients (n = 37, each group) for 30 min after starting the anhepatic period. The coagulation profiles, including thromboelastography, and biochemical profiles were measured before and 30 min after the end of infusion. Less impairment in the thromboelastography profiles and aPTT was observed in the high MW group. A higher calcium concentration and less reduction in platelet count were noted in the high MW group, but lactate accumulation was greater. In conclusion, a balanced salt-based high molecular weight HES solution is a more effective volume replacement during the anhepatic period of liver transplantation with respect to coagulation than a saline-based low molecular weight HES solution, although lactate accumulation is a possible concern.
