Low bispectral index values following electroconvulsive therapy associated with memory impairment.
It has been reported some patients have opened eyes with low bispectral index (BIS) values immediately following electroconvulsive therapy (ECT). We investigated the time course of the recovery from amnesia and BIS values. ⋯ The present study demonstrated a high frequency of patients falling asleep and the frequent occurrence of prolonged periods of low BIS values following ECT. The results of memory testing showed that ECT procedures resulted in amnesia. The ROC curve findings suggest a strong association of memory disturbance with BIS values. In conclusion, patients generally fell asleep, with low BIS values, for 1-2 h after ECT, and a prolonged period of impairment of memory formation was associated with low BIS values.

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.
