Randomized Controlled Trial Clinical Trial
Rapid induction of anesthesia with high concentrations of halothane or sevoflurane in children.
To compare the characteristics of the rapid induction of anesthesia in pediatric patients with high concentrations of sevoflurane or halothane, and to determine the ability of anesthesiologists to correctly identify the anesthetic drug when administered in this fashion. ⋯ The induction of anesthesia with high concentrations of either halothane or sevoflurane can be safely accomplished. Pediatric anesthesiologists can differentiate between halothane and sevoflurane when either drug is given in high initial concentrations. The presence of tachycardia may have served as the primary clue in determining which drug was being used.

Randomized Controlled Trial Clinical Trial
Moderate controlled hypotension with sodium nitroprusside does not improve surgical conditions or decrease blood loss in endoscopic sinus surgery.
STUDY OBJECTIVES To determine if moderate controlled hypotension can improve the dryness of the surgical field in endoscopic sinus surgery. ⋯ Intravenous anesthesia supplemented with N(2) is as effective as moderate controlled hypotension when blood loss, visibility in the surgical field, ACTH, AVP, and cortisol are examined.

Randomized Controlled Trial Clinical Trial
Determinants of core temperature at the time of admission to intensive care following cardiac surgery.
To determine the predictors of core temperature on arrival in the intensive care unit (ICU) after cardiac surgery. ⋯ To reduce the incidence of hypothermia after cardiac surgery, the most important variable is rewarming endpoint achieved before separation from bypass. A warm ambient temperature (>21 degrees C) may be beneficial if the duration of time in the OR after bypass is prolonged (>90 min).

Randomized Controlled Trial Clinical Trial
Pharmacodynamics and intubating conditions of cisatracurium in children during halothane and opioid anesthesia.
To determine the pharmacodynamics and intubating conditions of cisatracurium 0.2 mg/kg in children aged 2 to 12 years. ⋯ Cisatracurium 0.2 mg/kg offered acceptable intubating conditions at 90 seconds in 98% of pediatric patients, regardless of the anesthesia-based technique. Longer clinical duration in the halothane group in younger children may be due to age-related potentiation or to the small number of patients enrolled in the younger subgroup.
