preoperative administration of 5 micrograms/kg clonidine upon the alfentanil and droperidol …

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

Background Endotracheal intubation and extubation may cause undesirable hemodynamic
changes. Intravenous oxycodone has recently been introduced and used for relieving …

Purpose Clonidine not only stops postoperative shivering and decreases oxygen
consumption, but also decreases energy expenditure with or without a reduction in shivering …

Eighty normotensive female patients were studied in a randomized, double-blind
investigation, in which orally administered clonidine 0.1 mg, 0.2 mg and 0.3 mg were …

The authors studied 30 patients undergoing general anesthesia in order to evaluate whether
oral clonidine premedication could attenuate the hemodynamic changes associated with …

Background: Laparoscopy offers many benefits than conventional Cholecystectomy, but it
causes alteration of hemodynamic variables to some extent. The aim of this study is to …

We investigated the influence of intravenous clonidine 2, 4 and 6 μg kg− 1 on the
electroencephalogram and on the minimal alveolar concentration of isoflurane in 40 patients …

Background Marked activation of the sympathetic nervous system occurs during and after
noncardiac surgery. Low-dose clonidine, which blunts central sympathetic outflow, may …

Both clonidine and sevoflurane are interesting drugs for anaesthesia in maxillo-facial
