Randomized Controlled Trial Clinical Trial
Cardiovascular reflexes during anesthesia induction and tracheal intubation in elderly patients: the influence of thoracic epidural anesthesia.
To determine whether thoracic epidural anesthesia performed prior to general anesthesia provides hemodynamic protection from the stress of laryngoscopy and tracheal intubation; to access the autonomic reflex response to epidural anesthesia, general anesthesia, and airway stimulation. ⋯ Thoracic epidural blockade combined with general anesthesia was associated with preserved baroreflex function, and it afforded hemodynamic protection during laryngoscopy and tracheal intubation.

Randomized Controlled Trial Comparative Study Clinical Trial
Desflurane controls the hemodynamic response to surgical stimulation more rapidly than isoflurane.
To compare the control of hemodynamic response to surgical stimulus of desflurane to that of isoflurane. ⋯ Anesthetic depth can be more rapidly titrated with desflurane compared to isoflurane. Alveolar/inspired concentration ratio approaches unity more rapidly with desflurane anesthesia.

Randomized Controlled Trial Comparative Study Clinical Trial
Propofol-based anesthesia as compared with standard anesthetic techniques for middle ear surgery.
To determine if a total intravenous (i.v.) technique with propofol and fentanyl is superior to isoflurane anesthesia in patients undergoing middle ear surgery. ⋯ Propofol-fentanyl seems to be a better anesthetic than isoflurane-fentanyl in reducing the incidence of nausea and vomiting after middle ear surgery. Through the addition of droperidol to the isoflurane anesthetic seemed as effective, emergence from anesthesia was slower. For middle ear surgeries producing emesis, propofol-based anesthetics produced a rapid emergence with less nausea and vomiting.

Effect of preincision versus postincision infiltration with bupivacaine on postoperative pain.
To compare the efficacy of preincision wound infiltration with bupivacaine to wound infiltration at the end of the operation. ⋯ Wound infiltration, either preincision or postincision, had no clinically significant effect on the pain scores or analgesic requirements following abdominal hysterectomy.

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.
