Abstract:
The effect of intravenous vasopressin infusion in 5 patients with upper GI bleeding was studied by measuring portal blood flow velocity with pulsed Doppler ultrasound technique. In 4 of 5 patients portal blood flow velocity decreased at 1 hr after vasopressin infusion. In all patients the velocity decreased at 24 or 48 hrs. We think doppler is safe and useful method in the evaluation of vasopressin infusion therapy.
