Randomized Controlled Trial Clinical Trial
Xenon suppresses the hypnotic arousal in response to surgical stimulation.
To evaluate the suppressive effects of xenon (Xe) on hypnotic arousal at skin incision. ⋯ Unlike N2O, Xe was able to suppress hypnotic arousal in response to surgical stimulation when administered with sevoflurane.

Randomized Controlled Trial Comparative Study Clinical Trial
Effect of spinal versus general anesthesia on bladder compliance and intraabdominal pressure during transurethral procedures.
To evaluate the influence of spinal versus general anesthesia on bladder compliance and intraabdominal pressure in elderly males undergoing elective transurethral resection of the prostate. ⋯ Both spinal and general anesthesia induced a significant decrease in intraabdominal pressure. While both techniques were associated with an increase in bladder compliance, statistical significance was demonstrated only in the spinal anesthesia treatment group.

Comparative Study
A collaborative regional ocular anesthesia training program: successes and failures.
To describe a collaborative effort of the departments of ophthalmology and anesthesiology to teach anesthesiology residents regional ocular anesthesia; to detect any differences in positive or negative outcomes after blocks performed by anesthesiology residents versus blocks performed by ophthalmology residents. ⋯ Regional ocular anesthetic techniques can be safely and successfully taught to residents in anesthesiology.

To examine the effect of perfusion on accuracy of two pulse oximeters in children and to determine thresholds of perfusion below which these pulse oximeters become inaccurate or cease to function. ⋯ At the parameters explored in this study, the selected seven perfusion variables (age, weight, core and skin temperature, hemoglobin concentration, pulse pressure, and percent flow by laser Doppler) have little effect on accuracy of pulse oximetry in children.

Randomized Controlled Trial Clinical Trial
Optimal length and angle of a new lightwand device (Trachlight).
To investigate the effects of angle and length of the Trachlight lightwand and the effect of obesity on transillumination of the neck and difficulty of intubation. ⋯ To increase the success rate of tracheal intubation using the lightwand, the lightwand should be bent in 40 degrees to 60 degrees, with the extrusion of 1 to 2 cm from the tracheal tube. For obese patients with body weight > or = 120% of the standard, the lightwand was not useful.
