Dose fentanyl injection for blunting the hemodynamic response to intubation increase the risk of reflex bradycardia during major abdominal surgery?
BackgroundAlthough supplemental fentanyl has been widely used to blunt the hemodynamic responses to laryngoscopic intubation, its residual vagotonic effect may increase the risk of reflex bradycardia. We compared the incidence and severity of significant reflex bradycardia after a bolus injection of...
