Randomized Controlled Trial Comparative StudyIs there an advantage in using low-dose intrathecal bupivacaine for cesarean section?
Spinal anesthesia for cesarean section is associated with a high incidence of maternal hypotension. The aim of this study was to assess the efficacy of low-dose bupivacaine with fentanyl to reduce the incidence of hypotension in spinal anesthesia for cesarean section. ⋯ The development of hypotension after spinal block in subjects undergoing cesarean section was not prevented despite low-dose (4 mg) bupivacaine plus 25 microg fentanyl, but the severity of maternal hypotension, and the number of ephedrine treatments and the total dose of ephedrine were decreased.

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 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.
