Randomized Controlled Trial Clinical Trial
Use of propofol for office-based anesthesia: effect of nitrous oxide on recovery profile.
To evaluate the effect of nitrous oxide (N2O) on the recovery profile and the incidence of postoperative nausea and vomiting (PONV) after office-based surgery performed under propofol anesthesia. ⋯ In outpatients undergoing office-based surgical procedures with propofol anesthesia, administration of 65% N2O decreased the anesthetic requirement without increasing PONV. Therefore, use of a propofol-N2O combination may be a cost-effective alternative to propofol alone for office-based anesthesia.

Clinical Trial Controlled Clinical Trial
Pain relief in children following outpatient surgery.
To evaluate perioperative analgesia, prescription patterns, pain relief, and parental care of children undergoing outpatient surgery. ⋯ Despite a wide range of surgical procedures being performed on children on an ambulatory basis, current selection of patients for outpatient surgery is appropriate given the ability of the parents to manage their children's pain and to care for their children at home.

Advanced pulse oximeter signal processing technology compared to simple averaging. I. Effect on frequency of alarms in the operating room.
To determine the effect of a new signal processing technique (Oxismart, Nellcor, Inc., Pleasanton, CA) on the incidence of false pulse oximeter alarms in the operating room (OR). ⋯ Our study did not show a beneficial effect in the OR on the incidence of false alarms of the Nellcor monitor with Oxismart signal processing compared with the Criticare monitor with the longer averaging time of 21 seconds.

Randomized Controlled Trial Clinical Trial
Lightwand intubation does not reduce the increase in intraocular pressure associated with tracheal intubation.
To evaluate the changes in hemodynamic variables and intraocular pressure (IOP) after tracheal intubation using either lightwand or direct-vision laryngoscopy techniques. ⋯ We conclude that in healthy patients without ocular disease, using a lightwand intubating technique does not reduce the hemodynamic responses and increase in IOP associated with tracheal intubation as compared with conventional direct-vision laryngoscopy.

Clinical Trial Controlled Clinical Trial
Advanced pulse oximeter signal processing technology compared to simple averaging. II. Effect on frequency of alarms in the postanesthesia care unit.
To determine the effect of a new pulse oximeter (Nellcor Symphony N-3000, Pleasanton, CA) with signal processing technique (Oxismart) on the incidence of false alarms in the postanesthesia care unit (PACU). ⋯ To date, this is the first report of a pulse oximeter that produced almost no false alarms in the PACU.
