Randomized Controlled Trial Clinical Trial
Emergence characteristics of sevoflurane compared to halothane in pediatric patients undergoing bilateral pressure equalization tube insertion.
To compare the emergence characteristics of sevoflurane with halothane in pediatric patients having bilateral myringotomy and pressure equalization tube insertion using a highly standardized and common anesthetic technique. ⋯ In our institution there is a trend toward greater emergence agitation in ear tube placement patients given sevoflurane versus halothane anesthesia. Further, (with our discharge criteria) patients are actually discharged from the PACU and the hospital faster when given halothane as a sole anesthetic when compared to sevoflurane.

To evaluate the efficacy of tropisetron, a selective 5-HT(3) receptor antagonist, in preventing nausea and vomiting in high-risk inpatients undergoing various surgical procedures. ⋯ Prophylactic tropisetron can reduce the incidence of PONV in selected high-risk inpatients undergoing various types of surgical procedures.

Case Reports Clinical Trial
Noninvasive ventilation using bilevel positive airway pressure to treat impending respiratory failure in the postanesthesia care unit.
The author presents the use of noninvasive positive pressure ventilation using bilevel positive airway pressure (BiPAP) to treat respiratory insufficiency and hypoxemia in three patients in the postanesthesia care unit. BiPAP improved respiratory function with a decreased respiratory rate, decreased PaCO2, and improved oxygenation in the three patients. The applications of these techniques and equipment required are reviewed.

To investigate the effect of xenon on the endotracheal tube cuff in comparison to that of nitrous oxide. ⋯ Increase in pressure and gas volume was significantly less and slower with xenon than with nitrous oxide. More nitrous oxide passes into the cuff than xenon.

Cervical hematoma during placement of a catheter into the interscalene groove is a known complication of the procedure. I describe the occurrence of a hematoma while using a new system that is compatible with a nerve stimulator and offers the ability to aspirate during both needle placement and catheter insertion.
