Aims: The aim was to compare the effect of intravenous (IV) infusion of dexmedetomidine
and clonidine on the pressor response among patients undergoing tracheal intubation in …

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

Aims: The objective of this study is to compare the clinical effects of dexmedetomidine with
esmolol and control in attenuating the presser response during laryngoscopy. Settings and …

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

Background: The stress response to laryngoscopy and endotracheal intubation is a
commonly encountered physiological phenomenon. Though the response can be transient …

Background The pressor response, which is part of a huge spectrum of stress responses,
results from the increase in sympathetic and sympathoadrenal activity. This study was …

Background: Laryngoscopy and tracheal intubation after the induction of anesthesia are
nearly always associated with a sympathetic hyperactivity. To attenuate the pressor …

Background Direct laryngoscopy and tracheal intubation predictably lead to transient and
variable hemodynamic responses, which can be attenuated by α2-receptor agonists. The …

Methods: This prospective, randomised, comparative study was conducted in 100 American
Society of Anesthesiologists (ASA) I, II patients. The primary outcome was to evaluate the …

Background Laryngoscopy and tracheal intubation are strong stimuli that cause a reflex
increase in blood pressure (BP), heart rate (HR), and serum catecholamine level. These can …
