Randomized Controlled Trial Clinical Trial
Early anesthesia evaluation of the ambulatory surgical patient: does it really help?
To evaluate whether early evaluation by the anesthesiologist is more beneficial for the ambulatory surgical patient than a day-of-surgery visit. ⋯ Healthy ASA physical status I and II ambulatory surgical patients do not benefit from reducing preoperative anxiety by visiting the anesthesiologist prior to the day of surgery.

Randomized Controlled Trial Comparative Study Clinical Trial
Propofol versus thiamylal-enflurane anesthesia for outpatient laparoscopy.
To determine whether propofol anesthesia differs from thiamylal-enflurane anesthesia in induction characteristics, intraoperative hemodynamics, postoperative side effects, and postoperative psychomotor function recovery. ⋯ Induction and maintenance of anesthesia with propofol were comparable to those with thiamylal-enflurane, except patients experienced more pain on injection after propofol. Both immediate and intermediate recovery were more rapid after propofol anesthesia compared with enflurane-based anesthesia.

Randomized Controlled Trial Clinical Trial
Midazolam in combination with propofol for sedation during local anesthesia.
To compare the sedative, anxiolytic, and amnestic effects, as well as the recovery characteristics, when midazolam (vs. a placebo) is administered to patients receiving a propofol infusion for sedation during local anesthesia. ⋯ Premedication with midazolam 2 mg IV produced increased sedation, amnesia, and anxiolysis when administered immediately prior to the propofol infusion as part of a sedation technique for outpatient surgery. This combination did not prolong the recovery room stay when compared with propofol alone.

Randomized Controlled Trial Comparative Study Clinical Trial
Intraoperative warming therapies: a comparison of three devices.
To compare the effectiveness of three commonly used intraoperative warming devices. ⋯ The forced-air warmer applied to only a limited skin surface area transferred more heat and was clinically more effective (at maintaining central body temperature) than were the other devices. The characteristic early decrease in central temperature observed in all groups regardless of warming therapy is consistent with the theory of anesthetic-induced heat redistribution within the body.

Randomized Controlled Trial Clinical Trial
The effect of the prone position on venous pressure and blood loss during lumbar laminectomy.
To determine the effects of three different prone support systems (Andrews spinal surgery frame, Cloward surgical saddle, and longitudinal bolsters) on inferior vena cava (IVC) and superior vena cava (SVC) pressures; the validity of measuring central venous pressure (CVP) for the determination of ideal positioning of the patient; and the relationship among frame type, blood loss, and hemodynamic measurements. ⋯ Increased blood loss was not associated with increased SVC or IVC pressure, nor was there any significant correlation between any demographic or hemodynamic variable and blood loss. There was no evidence that CVP is useful in determining the ideal prone position in patients undergoing lumbar laminectomy.
