The effect of ethanol intoxication on hemostasis after liver resection was studied
in the rat. Plasma levels of ethanol were within the range of those found in ethanol
intoxication in man. Bleeding time and blood loss were significantly increased, whereas
hemoglobin and hematocrit values were decreased after resection in intoxicated animals
compared to controls. APT-times and platelet counts did not differ significantly between
the two groups of rats. ADP- and collagen-induced platelet aggregation was slightly
inhibited one hour after ethanol administration in non-operated animals. A decrease
in pH, such as observed in intoxicated animals, did not affect hemostasis. Distribution
of cardiac output was significantly altered after ethanol intoxication. Renal blood
flow was increased by 54%, blood flow in the hepatic artery by 40% and in the portal
vein by 47%.
