Fentanyl Attenuates the Hemodynamic Response to Endotracheal Intubation More Than the Response to Laryngoscopy

Abstract

We assessed the effectiveness of avoiding laryngoscopy for orotracheal intubation. There was no significant difference in the hemodynamic responses to orotracheal intubation by fiberscopy and laryngoscopy without fentanyl pretreatment, whereas 2 microg/kg fentanyl significantly reduced the hemodynamic responses in the group intubated by fiberscopy. Pretreatment of fentanyl and fiberoptic intubation might be recommended for avoiding hyperdynamic responses.
