AbstractThe effects of hydroxyethyl starch (HES) on hemostasis were investigated extensively. In order to simulate acute blood loss due to surgery or trauma, one unit (450 ml) of blood was drawn from normal healthy men. This was followed by a 1-liter infusion over 60 minutes of either 6 percent HES, 5 percent albumin, or 0.9 percent sodium chloride (NaCl) as replacement. Coagulation studies were performed before phlebotomy, before infusion and at 0, 4, 20, 27, and 92 hours following infusion. Following infusion of HES and albumin, plasma fibrinogen and antithrombin-III levels fell slightly due to plasma volume expansion and hemodilution. In subjects receiving HES, partial thromboplastin times (PTTs) were significantly (p less than .05) prolonged and factor VIII activities were significantly (p less than .05) decreased when compared to the albumin and NaCl groups. These findings could not be attributed solely to hemodilution. The effects of HES on PTT and factor VIII could not be correlated with plasma HES levels; neither could they be reproduced in vitro by mixing HES with normal plasma. Mean values of the following studies remained normal after infusion of all replacement fluids: prothrombin time, bleeding time, fibrin monomer, fibrin-fibrinogen degradation products, platelet adhesion, circulating platelet aggregates, and platelet count.(ABSTRACT TRUNCATED AT 250 WORDS)
