Randomized Controlled Trial Clinical Trial
Active warming, not passive heat retention, maintains normothermia during combined epidural-general anesthesia for hip and knee arthroplasty.
to compare passive heat retention by low-flow anesthesia, alone and with additional thermal insulation by reflective blankets, with forced-air warming preventing intraoperative hypothermia during combined epidural-general anesthesia. ⋯ During combined epidural-general anesthesia for elective hip and knee arthroplasty, passive heat retention by means of low-flow anesthesia alone and in combination with reflective blankets is ineffective in maintaining intraoperative normothermia and definitely inferior to active forced-air warning.

Catheters used to facilitate extubations of the known difficult airway are usually placed through an existing endotracheal tube (ETT), prior to its removal. We present a case in which a #11 Cook airway exchange catheter was placed adjacent to the ETT and left intratracheal for an extended period following removal of the ETT.

To identify variables influencing the likelihood of unanticipated admission following scheduled ambulatory surgery. ⋯ Surgery duration of 60 minutes or longer was the most important predictor of unanticipated admission following scheduled ambulatory surgery.

Randomized Controlled Trial Comparative Study Clinical Trial
Ondansetron versus droperidol or placebo when given prophylactically for the prevention of postoperative nausea and vomiting in patients undergoing middle ear procedures.
To compare the prophylactic administration of ondansetron with droperidol or placebo to determine its effectiveness in reducing postoperative nausea and vomiting after middle ear procedures. ⋯ Ondansetron 4 mg i.v. is as effective as droperidol and better than placebo in preventing nausea and vomiting in patients undergoing middle ear surgery. No cost advantage as determined by lower use of rescue antiemetics or shorter PACU times was noted after the prophylactic administration of ondansetron.

Randomized Controlled Trial Clinical Trial
Reduction of propofol injection pain with a double lumen i.v. set.
To investigate if the use of a new double lumen i.v. set (DLIS) decreases the incidence of propofol injection pain compared with single lumen i.v. set (SLIS) administration. ⋯ The DLIS significantly reduced the incidence of propofol injection pain compared with SLIS. Further studies are indicated to evaluate the cost-effectiveness of this device.
