Effect of vasopressin on hemodynamic variables, organ blood flow, and acid-base status in a pig model of cardiopulmonary resuscitation.

Based upon the hypothesis that vasopressin (antidiuretic hormone) may increase vascular resistance during ventricular fibrillation, the effects of this potent vasoconstrictor were studied in a porcine model of ventricular fibrillation. Vasopressin therapy was compared to epinephrine by randomly allocating 14 pigs to receive either 0.045 mg/kg of epinephrine… (More)
