Clonidine, recently introduced into anesthesia practice, may cause bradycardia. Whether
this bradycardia is reversible with atropine is not known. Accordingly, we studied heart rate …

Abstract Changes in mean arterial blood pressure (MAP) and heart rate (HR) during short
duration direct laryngoscopy and tracheal intubation were determined in 24 patients …

In a randomized, double-blind placebo controlled study, intravenous clonidine, fentanyl and
saline were compared for both their effect on the cardiovascular response to intubation, and …

Observations of arterial blood pressure, heart rate and cardiac rhythm during endotracheal
intubation and within a five minute period thereafter were made in 80 patients randomly …

Laryngoscopy and intubation are associated with stress response changes like tachycardia,
hypertension and dysrhythmias. The hemodynamic responses during laryngoscopy and …

Materials and Methods: This prospective study was done in sixty patients undergoing
noncardiac surgeries of American Society of Anesthesiologists health status Class I and II …

Background: The present study was designed to compare the effect of intravenous fentanyl
and esmolol for the attenuation of hemodynamic responses to laryngoscopy and intubation …

This study was designed to evaluate the dose-response effects of different doses of
clonidine on the stress response to laryngoscopy and endotracheal intubation. In a …

Background: Cardiovascular response to laryngoscopy and intubation are recognized since
long and various attempts have been made to attenuate this response. The aim of this study …

This study was undertaken to determine whether lidocaine and/or alfentanil can effectively
abolish or attenuate the increase in mean arterial pressure (MAP), heart rate (HR), and rate …
