Regional anesthesia is becoming increasingly popular among anesthesiologists in the
management of postoperative analgesia following pediatric surgery. The main objective of …

Background Dexmedetomidine, an alpha-2 agonist, has been used for attenuation of
hemodynamic response to laryngoscopy but not through the nebulized route. We evaluated …

Background: Percutaneous tracheostomy, almost associated with cough reflex and
hemodynamic fluctuations, is a common procedure for traumatic brain injury (TBI) patients …

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

Background The α 2-adrenergic agonist dexmedetomidine (DEX) is a sedative and can be
used as an adjunct to hypnotics. The study sought to evaluate the effects of different doses of …

Purpose Ciprofol is a recently developed short-acting gamma-aminobutyric acid receptor
agonist with a higher potency than that of propofol. As a new sedative drug, there are few …

Methods: Sixty patients were randomly allocated to receive scalp block with 25 ml of 0.5%
ropivacaine added with either normal saline (control group) or dexmedetomidine (1 μg/kg) …

Introduction The insertion of a double-lumen tracheal tube may cause a transient but more
intense sympathetic response. We examined the effects of esketamine vs. dexmedetomidine …

Hypertension is a common preexisting diagnosis in surgical patients, reported by nearly one-
third of adult patients presenting for noncardiac procedures and two-thirds of those …

Objectives To compare the hemodynamic response and sedation score between
intravenous and nebulized dexmedetomidine as premedication for the attenuation of the …
