Randomized Controlled TrialLow dose of fentanyl reduces predicted effect-site concentration of propofol for flexible laryngeal mask airway insertion.
In contrast to reports on the classical laryngeal mask airway (classical LMA; CLMA), no report has calculated the 50% and 95% effect-site concentrations (EC(50) and EC(95), respectively) of propofol required for flexible LMA (FLMA) insertion. This study was designed to determine the EC(50) and EC(95) of propofol for FLMA insertion, using probit analysis, and to investigate whether supplemental 0.25 microg x kg(-1) fentanyl decreased these concentrations. ⋯ The propofol EC(50) for FLMA insertion was decreased by supplemental 0.25 microg x kg(-1) fentanyl without BIS, hemodynamic, or respiratory depression.

Randomized Controlled TrialEffect of landiolol hydrochloride on suxamethonium-induced neuromuscular block.
The aim of this study was to examine the effect of landiolol hydrochloride, an ultrashort-acting beta(1)-blocker, on suxamethonium-induced neuromuscular block. ⋯ Landiolol delayed recovery from suxamethonium-induced paralysis. However, the interaction between the drugs seemed to be small in the clinical setting.

Randomized Controlled TrialThe impact of two arterial catheters, different in diameter and length, on postcannulation radial artery diameter, blood flow, and occlusion in atherosclerotic patients.
Arterial cannulation is a common intervention in anesthesia practice. However, the success rates and complications of radial arterial cannulation with 20-G or smaller catheters in patients with atherosclerosis have been underevaluated. The aim of this prospective randomized study was to compare the efficacy of and complications with 20- and 22-G catheters for radial arterial cannulation in atherosclerotic patients. ⋯ A 22-gauge catheter for radial arterial cannulation in patients with atherosclerosis provides unchanged postcannulated radial artery diameter, decreases postcannulation complications, and improves the first-attempt success rate.

Randomized Controlled TrialEffects of intravenous adenosine 5'-triphosphate on intraoperative hemodynamics and postoperative pain in patients undergoing major orofacial surgery: a double-blind placebo-controlled study.
We conducted a double-blind placebo-controlled study to investigate the effects of the intraoperative intravenous infusion of adenosine 5'-triphosphate (ATP) on intraoperative hemodynamics and postoperative pain in patients undergoing major orofacial surgery. ⋯ Our data suggest that intraoperative ATP infusion can blunt hemodynamic responses to surgical stimuli and produce prolonged analgesia in patients undergoing major orofacial surgery.

Randomized Controlled TrialThe effect of oral and IV ramosetron on postoperative nausea and vomiting in patients undergoing gynecological laparoscopy with total intravenous anesthesia.
Ramosetron can be administered orally as well as intravenously. We investigated the effect of oral ramosetron on postoperative nausea and vomiting (PONV) in patients undergoing gynecological laparoscopy. ⋯ The effect of oral ramosetron 0.1 mg was comparable to that of IV ramosetron 0.3 mg on the prevention of PONV in women undergoing gynecological laparoscopy with TIVA. Both the oral and IV forms were effective at preventing PONV during the first 1 h after surgery.
