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.

Review Case Reports
Hypermagnesemia-induced cardiopulmonary arrest before induction of anesthesia for emergency cesarean section.
We describe a 42-yr-old woman scheduled for emergency cesarean section who had sudden cardiopulmonary arrest just before induction of general anesthesia. Hypermagnesemia, caused by accidental overdose of magnesium sulfate during transportation to the operating room, was the primary cause of this life-threatening event. Anesthetic management after such events and a brief summary of the literature regarding iatrogenic hypermagnesemia in obsteric patients are provided.

To assess an anesthetic technique achieving spontaneous breathing through the laryngeal mask airway (LMA) during combined epidural block and propofol anesthesia. ⋯ The best infusion dose of propofol to achieve spontaneous breathing with the LMA seems to be 5 mg/kg/h, and the present balanced regional anesthesia with the LMA, using propofol infusion at 1.5 to 2.0 mg/kg and 5 mg/kg/h combined with epidural block, may be useful in clinical practice for lower extremity and lower abdominal gynecologic operations.

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).
