Comparative Study
Which is the safest endotracheal tube for use with the CO2 laser? A comparative study.
To compare the efficacy of special endotracheal tubes manufactured for carbon dioxide (CO2) laser surgery with foil-wrapped and plain red rubber (RR) endotracheal tubes. ⋯ Copper foil-wrapped RR tubes, aluminum foil-wrapped RR tubes, or stainless steel tubes are recommended for laser airway surgery.

The laryngeal mask airway (LMA) is a new concept in airway management. A miniature inflatable mask is positioned in the hypopharynx, forming a low-pressure seal around the laryngeal inlet. The mask is attached via a tube to the breathing circuit. ⋯ It is now widely used in the United Kingdom; however, it is not yet available for sale in the U. S. It has already had a major effect on practice in Britain and has the potential to do the same in the United States.

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 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
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.
