UNLABELLED Heart rate (HR) response to IV atropine is attenuated during propofol-nitrous oxide (N(2)O) anesthesia. We studied the effects of propofol-N(2)O anesthesia on isoproterenol-induced HR changes. The control group (n = 15) received no propofol and no N(2)O. Patients in the propofol-N(2)O group (n = 21) received IV propofol 2.5 mg/kg over 1 min followed by a continuous infusion of propof...

BACKGROUND Propofol is a rapid, efficient hypnotic agent with antiemetic effects. However, a high dosage is related to hemodynamic abnormalities such as hypotension and bradycardia. Pretreatment with remifentanil can decrease injection pain and stabilize hemodynamics during the induction period. Remifentanil or midazolam in combination with propofol can provide synergistic or additive effects d...

BACKGROUND Images evoked immediately before the induction of anesthesia with the help of suggestions may influence dreaming during anesthesia.The aim of the study was to assess the incidence of evoked dreams and dream recalls by employing suggestions before induction of anesthesia while administering different general anesthetic combinations. METHODS This is a single center, prospective rando...

Objective: The aim of the study was to compare ventilatory effect between propofol deep sedation technique with and without midazolam in hepatic tumor patients undergoing radiofrequency ablation procedure. Methods: Three hundred seventy-four who underwent procedure a single year were randomly assigned group (A, n = 187) (B, 187). Patients A received normal saline, those B 0.02 mg/kg intravenous...

The purpose of this study was to investigate the renal protective efficacy propofol, ketamine, and ketofol in an ischemia/reperfusion injury (IRI) model experimentally induced rats. Thirty-five male Sprague-Dawley rats were randomly assigned into five groups: sham (Group 1), control 2), ketamine 3), propofol 4), 5). Following administration intramuscular hydrochloride anesthesia, left hilum exp...

BACKGROUND The cuffed oropharyngeal airway (COPA) is a modified Guedel-type oral airway with a cuff at its distal end. The objectives of this prospective, randomized study were to compare the COPA and the laryngeal mask airway (LMA) in terms of propofol requirement with and without fentanyl pretreatment for smooth insertions. METHODS Seventy-five patients undergoing general anaesthesia were r...

BACKGROUND The physicochemical properties of propofol could allow diffusion across the alveolocapillary membrane and a measurable degree of pulmonary propofol elimination. The authors tested this hypothesis and showed that propofol can be quantified in expiratory air and that propofol breath concentrations reflect blood concentrations. This could allow real-time monitoring of relative changes i...
