We have studied the effect of clonidine pretreatment on cardiovascular responses to various
stimuli during craniotomy. Fifty-eight patients (ASA Class I–II), scheduled for supratentorial …

BACKGROUND: We carried out this study to compare the efficacy of oral gabapentin and
clonidine premedication for controlling the pressor responses to laryngoscopy and tracheal …

Background: Laryngoscopy and tracheal intubation are noxious stimuli which evoke a
transient but marked sympathetic response. Alpha-2 adrenoceptor agonists attenuate the …

Background: Laryngoscopy and intubation evokes a transient but marked sympathetic
response manifesting as increase in heart rate, blood pressure & arrhythmias. We …

STUDY OBJECTIVE: To investigate the effects of intravenous (IV) versus oral clonidine on
alterations of heart rate (HR), mean arterial pressure (MAP), cardiac output (CO), and …

Background: Laparoscopic cholecystectomy under general anesthesia induced
intraoperative hemodynamic responses which should be attenuated by appropriate …

Background and objective This study compares the effect of oral clonidine vs. hydroxyzine
on the haemodynamic and catecholamine responses to microlaryngoscopy. Methods Thirty …

Although oral clonidine premedication is known to reduce the hemodynamic response
under general anesthesia, effects on the hemodynamic response during sedated fiberoptic …

Background Clonidine and dexmedetomidine are alpha-2 agonists with beneficial effect on
the hemodynamic response to laryngoscopy and intubation. The present study was …

Background Laryngoscopy and tracheal intubation are known to increase sympathetic
activity that may be detrimental to patients with pre-existing ischemic or hypertensive heart …
