Based on laboratory and clinical data from our institution, 113 patients
with cirrhosis, portal hypertension, and acute hemorrhage from esophageal
varices were treated with high-dose vasopressin arginine (1 to 1.5 U/min)
to control the acute bleeding and reduce blood loss during portosystemic
shunt operations. Compared with patients receiving a lower dose of
vasopressin infusion, these patients had a reduction in both postoperative
mortality (21% vs 6%) and the proportion of patients requiring emergency
operation (40% vs 18%). A decrease in operative blood loss (1340 vs 793 mL)
was also seen. Adverse effects of vasopressin were increased by high-dose
infusion, but no significant morbidity occurred. These results suggest that
high-dose vasopressin infusion can reduce the mortality of acute variceal
hemorrhage and porto-systemic shunting primarily by allowing patients to
improve hepatic function prior to an elective operation and by decreasing
intraoperative blood loss.
