Randomized Controlled Trial Clinical Trial
Preoperative clonidine attenuates stress response during emergence from anesthesia.
To investigate whether a single preoperative IV dose of clonidine blunts the hemodynamic and hyperadrenergic responses not only to intubation, but also to extubation. ⋯ A single preoperative IV dose of clonidine (3 microg/kg) blunts the hemodynamic responses due to extubation in noncardiac surgery of intermediate duration.

Randomized Controlled Trial Clinical Trial
Sevoflurane-N2O versus propofol/isoflurane-N2O during elective surgery using the laryngeal mask airway in adults.
To compare a sevoflurane-nitrous oxide (N2O) general anesthetic technique with a standard technique of propofol for induction, and isoflurane-N2O for maintenance. ⋯ Sevoflurane-N2O and propofol provided comparable conditions for LMA insertion. Sevoflurane-N2O was not associated with a faster return of consciousness or faster time to exit the OR compared with isoflurane-N2O.

Randomized Controlled Trial Clinical Trial
Emergence characteristics of sevoflurane compared to halothane in pediatric patients undergoing bilateral pressure equalization tube insertion.
To compare the emergence characteristics of sevoflurane with halothane in pediatric patients having bilateral myringotomy and pressure equalization tube insertion using a highly standardized and common anesthetic technique. ⋯ In our institution there is a trend toward greater emergence agitation in ear tube placement patients given sevoflurane versus halothane anesthesia. Further, (with our discharge criteria) patients are actually discharged from the PACU and the hospital faster when given halothane as a sole anesthetic when compared to sevoflurane.

Randomized Controlled Trial Clinical Trial
Warmed humidified inspired oxygen accelerates postoperative rewarming.
To investigate the efficacy of warmed, humidified inspired oxygen (O(2)) for the treatment of mildly hypothermic postoperative patients. ⋯ Warming and humidifying inspired O(2) hastens recovery from hypothermia in postoperative patients.

Randomized Controlled Trial Clinical Trial
0.2% ropivacaine with or without fentanyl for patient-controlled epidural analgesia after major abdominal surgery: a double-blind study.
To evaluate the effects of adding low concentration of fentanyl to 0.2% ropivacaine when providing patient-controlled epidural analgesia (PCEA) outside the Post-Anesthesia Care Unit. ⋯ A thoracic epidural infusion of 0.2% ropivacaine, with or without fentanyl, provided effective pain relief in most patients with a very low degree of motor blockade. Adding 2 microg/ml fentanyl to 0.2% ropivacaine reduced total consumption of local anesthetic solution and need for incremental doses, but did not provide clinically relevant advantages in quality of pain relief and incidence of motor block, leading to a significant decrease in peripheral SpO(2), lasting up to 48 hours after surgery.
