Effects of fentanyl on peripheral and cerebral hemodynamics in neonatal lambs.

abstract：BACKGROUND:Dysrhythmias and death occur in patients with acquired long QT syndrome (LQTS). Little information exists regarding interactions between anesthetics and drugs that prolong ventricular repolarization. Therefore the effects of three commonly used intravenous anesthetics on ventricular repolarization were inves...
