title: Intraarterial vasopressin in the treatment of upper gastrointestinal hemorrhage: a prospective, controlled clinical trial.
abstract: Intraarterial vasopressin has been reported to be effective in the treatment of massive upper gastrointestinal hemorrhage. A prospective, controlled clinical trial comparing conventional treatment with conventional therapy plus intraarterial vasopressin was undertaken. Sixty episodes of upper gastrointestinal hemorrhage were evaluated during a 40-month period; 32 received conventional and 28 conventional plus vasopressin therapy. The two groups of patients were similar in type and severity of their bleeding lesions and in their underlying diseases. Vasopressin was more effective in controlling hemorrhage from nonvariceal lesions (P less than 0.05) and from varices (P less than 0.01) than conventional therapy. Transfusion requirements were significantly reduced in those patients who received vasopressin. Paradoxically, survival was not affected by vasopressin administration. The failure of cessation of hemorrhage to improve survival is thought to be due to the degree of advancement of the underlying disease, to the torrential nature of the hemorrhage, to the frequency of recurrent hemorrhage, and to the use of intraarterial vasopressin in some patients in the conventional treatment group in whom conventional therapy had failed.
