OBJECTIVE: To compare the effect on postresuscitation left ventricular function of vasopressin vs. epinephrine used during cardiopulmonary resuscitation in a swine model of prolonged prehospital ventricular fibrillation. DESIGN: Prospective, randomized experimental study. SETTING: University large animal resuscitation research laboratory. SUBJECTS: Forty-eight swine (29 +/- 1 kg). INTERVENTIONS: Resuscitation after 12.5 mins of untreated ventricular fibrillation, randomizing animals during cardiopulmonary resuscitation to treatment with epinephrine, vasopressin, or vasopressin followed by a vasopressin antagonist administered in the postresuscitation period. MEASUREMENTS AND MAIN RESULTS: Serial measurements of left ventricular systolic and diastolic function (prearrest, postresuscitation at 30 mins and 6 hrs) and 24-hr survival. Animals receiving vasopressin had more postresuscitation left ventricular dysfunction than those receiving epinephrine (p < .05). The vasopressin antagonist produced vasodilation and improved early postresuscitation left ventricular systolic and diastolic function but did not have a lasting effect on such postresuscitation ventricular function and decreased 24-hr survival compared with the use of vasopressin alone (3/16 vs. 10/16 survivors; p < .05). CONCLUSIONS: Vasopressin use during cardiopulmonary resuscitation results in worse postresuscitation left ventricular function early but did not compromise 24-hr outcome. Reversal of vasopressin's effect with a specific V-1 antagonist in the postresuscitation period did not improve survival.
