Vasopressin Versus Norepinephrine in Patients With Vasoplegic Shock After Cardiac Surgery

(Abstracted from Anesthesiology, 126(1):85–93, 2017) The purpose of this prospective, double-blind, randomized controlled trial was to gauge whether vasopressin is superior to norepinephrine in reducing postoperative complications in patients with vasoplegic syndrome. This complication, which presents in 5% to 25% of cardiac surgery patients, is characterized by low arterial pressure with either normal or elevated cardiac output but reduced systemic vascular resistance.
