Randomized Controlled Trial Clinical Trial
Pre-induction skin-surface warming minimizes intraoperative core hypothermia.
To test the hypothesis that only one hour of preinduction skin-surface warming decreases the rate at which core hypothermia develops during the first hour of anesthesia. ⋯ A single hour of preoperative skin-surface warming reduced the rate at which core hypothermia developed during the first hour of anesthesia. Preoperative skin surface warming is particularly helpful during short procedures because redistribution hypothermia is otherwise difficult to treat.

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.

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
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.

The effect of cricoid pressure application on airway patency.
To assess the incidence of upper airway obstruction associated with the application of cricoid pressure (Sellick's maneuver) by experienced anesthetists. ⋯ The use of manual cricoid pressure, even by experienced anesthetists, causes a degree of airway obstruction and can cause complete airway occlusion.
