Randomized Controlled Trial Clinical Trial
Postoperative hemodynamic and thermoregulatory consequences of intraoperative core hypothermia.
To evaluate the postoperative hemodynamic and thermoregulatory consequences of intraoperative core hypothermia. ⋯ These data confirm that the effects of intraoperative hypothermia on postoperative HR and BP are modest in relatively young, generally healthy patients. In contrast, intraoperative hypothermia caused substantial postoperative thermal discomfort, and full recovery from hypothermia required many hours. Delayed return to care normothermia apparently resulted largely from postoperative thermoregulatory impairment.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of sevoflurane and halothane anesthesia in children undergoing outpatient ear, nose, and throat surgery.
To compare the induction, maintenance, and recovery characteristics of sevoflurane and halothane in pediatric ambulatory patients undergoing adenoidectomy with or without myringotomies (BMTs). To compare the hemodynamic effects of the two drugs. ⋯ Sevoflurane provides a faster anesthetic emergence and recovery than halothane in premedicated patients but it does not expedite meeting current home discharge criteria.

Randomized Controlled Trial Comparative Study Clinical Trial
Hemodynamic comparison of direct vision versus blind oral endotracheal intubation.
To determine the hemodynamic response to airway manipulation and endotracheal intubation by comparing the direct oral method of the Macintosh laryngoscope to the blind oral method of the Augustine guide. ⋯ The Augustine guide, a new technique for orally intubating patients blindly and when head and neck manipulations are contraindicated, had less of an effect on HR compared with the Macintosh laryngoscope. Minimal lifting of the tongue and mandible required with the Augustine guide could account for the decreased HR response. The Augustine guide appears to be a promising new addition to the airway armamentarium and deserves further testing.

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 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.
