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.

Multicenter Study
Use of esophageal or precordial stethoscopes by anesthesia providers: are we listening to our patients?
To ascertain current anesthesia utilization of esophageal and precordial stethoscopes in U.S. anesthesia training programs. ⋯ Our data suggest infrequent utilization of esophageal and precordial stethoscopes in anesthesia training institutions. Thus, current anesthesia training may be fostering an environment where providers overlook a valuable minimally invasive, and cost-effective continuous monitor of patients' dynamic vital organ function.

To study whether a detailed radiographic examination of neck and upper airway can help identify normal looking patients in whom endotracheal intubation may be difficult; determine whether such parameters as identified by magnetic resonance imaging (MRI) can also be identified in a soft tissue radiograph; and to study the correlation between oropharyngeal appearance, based on Mallampati's classification, and laryngoscopic findings in a large number of patients requiring endotracheal intubation. ⋯ No significant difference between the two groups could be identified on soft tissue radiography or MRI scans.

To determine whether saline soaked pledgets would protect the cuffs of polyvinylchloride (PVC) endotracheal tubes from carbon dioxide (CO2) laser-induced combustion. ⋯ Under the conditions of this experiment, saline soaked pledgets protected PVC endotracheal tube cuffs from the CO2 laser.
