Randomized Controlled Trial Comparative Study Clinical Trial
The efficacy of guanfacine in reducing perioperative hemodynamic changes and volatile anesthetic requirement.
To evaluate the efficacy of guanfacine, an alpha 2-adrenergic agonist, for attenuating hemodynamic changes associated with tracheal intubation or extubation, providing intraoperative hemodynamic stability, and reducing inhalation anesthetic requirement in patients undergoing gynecologic surgery. ⋯ Guanfacine 1 mg administered orally proved to be an effective premedicant for providing intraoperative hemodynamic stability, attenuating the increase in BP and HR associated with tracheal intubation and extubation, and reducing anesthetic requirements without increasing the incidence of perioperative complications.

Randomized Controlled Trial Comparative Study Clinical Trial
Sevoflurane versus halothane for general anesthesia in pediatric patients: a comparative study of vital signs, induction, and emergence.
To compare vital signs and the speed of induction and emergence with sevoflurane versus halothane in pediatric patients. ⋯ Induction of and emergence from anesthesia was faster with sevoflurane than halothane. Airway complications were low in both groups. Vital signs were more stable with sevoflurane during induction through intubation, and were comparable during maintenance. Sevoflurane is an excellent drug for inhalational induction in pediatric patients.

Randomized Controlled Trial Clinical Trial
Use of patient-controlled analgesia with alfentanil for extracorporeal shock wave lithotripsy.
To compare the efficacy of patient-controlled analgesia (PCA) to physician-controlled analgesia in patients undergoing extracorporeal shock wave lithotripsy (ESWL). ⋯ PCA is a useful alternative to physician-controlled analgesia during ESWL since it provides equivalent pain control while using less alfentanil.

Randomized Controlled Trial Comparative Study Clinical Trial
Does monitoring end-tidal isoflurane concentration improve titration during general anesthesia?
To assess the value of end-tidal anesthetic gas monitoring with respect to intraoperative hemodynamic stability and recovery times. ⋯ This study suggests that end-tidal isoflurane monitoring does not improve the titration of isoflurane during general anesthesia.

Efficient inspired concentration of sevoflurane for vital capacity rapid inhalation induction (VCRII) technique.
To evaluate the efficient inspired concentration of sevoflurane for a vital capacity rapid inhalation induction (VCRII) technique with respect to induction time, characteristics, and acceptability. ⋯ Sevoflurane 6% can be recommended for VCRII, but increasing the concentration higher than this does not markedly shorten the induction time and thus seems to add little benefit.
