Clonidine, an α 2-adrenergic agonist, augments the pressor response to intravenous
ephedrine. If this effect is partly due to clondine-induced potentiation of α 1-adrenoceptor …

IMPLICATIONS: In 80 patients undergoing carotid endarterectomy under regional
anesthesia, supplemental clonidine infusion (1 μg· kg− 1· h− 1) suppressed the …

Twenty‐eight patients presenting for aortic surgery were randomly assigned in a double‐
blind, placebo‐controlled protocol to receive placebo (n= 14) or clonidine (4.7±1.2 μg· kg‐1 …

Background: We compared the effects of oral clonidine and gabapentin as premedicant in
obtunding hemodynamic response to laryngoscopy and intubation in normotensive patients …

Study Objective: To evaluate oral clonidine and intravenous esmolol in blunting
hemodynamic changes associated with intranasal injection of an epinephrine-containing …

Purpose: Intrathecal morphine administered prior to coronary artery revascularization
(CABG) surgery was studied to determine its effects on the stress response. Methods: In a …

It has been suggested that postjunctional alpha 1-adrenoceptor mediated vasoconstriction is
enhanced by clonidine. We have examined in humans if the pressor responses to …

Objective Surgical trauma results in diffuse sympathoadrenal activation which is thought to
contribute to perioperative cardiovascular complications in high-risk patients. Regional …

The authors describe the case of a 48-year-old man admitted to the critical care unit (CCU)
who presented with septic shock and treated conventionally with volume loading and …

Background: Both magnesium and clonidine are known to inhibit catecholamine and
vasopressin release and attenuate hemodynamic response to pneumoperitoneum. This …
