Clonidine decreases the stress-induced sympathoadrenal responses to painful stimuli and
improves hemodynamic stability during general anesthesia. Because acute hypertensive …

Design: A prospective, randomized, comparative, double-blind study with a sample size of
sixty patients. Methods: Sixty patients undergoing elective neurosurgery were randomly …

Clonidine diminishes sympathetic nervous system activity via a central action. To test if the
haemodynamic responses to ketamine, a centrally acting sympathomimetic drug, are …

Study Objective: To determine the effects of oral clonidine premedication on hemodynamic
changes during the entire course of ketamine anesthesia and incidence of postoperative …

In this controlled study, we compared clonidine with conventional premedication in 35
patients undergoing coronary artery bypass grafting (CABG). After premedication with …

Abstract Study Objective: To determine whether a 300 μg dose of oral clonidine given 90
minutes prior to laryngoscopy and intubation provides hemodynamic protection from the …

The effects of clonidine, a centrally acting alpha 2-adrenergic receptor agonist, on depth of
fentanyl anesthesia and on cardiovascular response to laryngoscopy and intubation were …

We studied pressor responses and changes in plasma catecholamine concentrations
following two consecutive doses of ephedrine 0.1 mg. kg‐1 with (n= 20) and without (n= 20) …

Background In many studies investigating measures to attenuate the hemodynamic and
humoral stress response during induction of anaesthesia, primary attention was paid to the …

outflow leading to decreased heart rate, enhanced baroreflex sensitivity and depressed AV
node conduction. 6 The efficacy of epidural or intrathecal or-2 agonists stems from their …
