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.

To assess the effects of implementing an ambulatory and same-day surgery preoperative evaluation patient triage system over a 3-year period. ⋯ Efficient, cost-effective patient care can be provided by using this preoperative evaluation model. Some institutions may find portions of this preoperative model applicable to their current situation.

Multicenter Study Clinical Trial
Relationship between clinical history, coagulation tests, and perioperative bleeding during tonsillectomies in pediatrics.
To determine the value of clinical history and preoperative coagulation tests. ⋯ Preoperative assessment based on the history of bleeding cannot predict abnormal laboratory tests. Neither the history of bleeding or laboratory tests can predict postoperative bleeding.
