This study determines the flammability of polyvinylchloride (PVC), red rubber (RR), and silicone (Si) endotracheal tubes in oxygen- and nitrous-oxide-enriched atmospheres. Flammability is measured by using the oxygen and nitrous oxide indices of flammability with laser ignition. ⋯ These results are similar to the previously reported O2 and N2O indices of flammability with propane-torch ignition. This study validates the concept that the indices of flammability are useful measures of endotracheal tube flammability and are independent of the ignition source.

The widely practiced rapid-sequence induction with application of cricoid pressure is designed to facilitate endotracheal intubation in patients considered to be at high risk of aspiration. We describe a case in which this maneuver was performed on a patient with an undiagnosed traumatic injury to the larynx. The resulting airway obstruction required emergency surgical intervention. The clinical presentation, diagnosis, and management of such injuries are discussed.

Randomized Controlled Trial Comparative Study Clinical TrialEmergence airway complications in children: a comparison of tracheal extubation in awake and deeply anesthetized patients.
We compared the differences in oxygen saturation and airway-related complications after tracheal extubation in pediatric patients undergoing elective strabismus surgery or adenoidectomy and/or tonsillectomy who were awake versus anesthetized. Seventy otherwise healthy patients between 2 and 8 yr of age were studied. Anesthesia was induced with halothane or thiamylal and maintained with nitrous oxide and halothane. ⋯ There were no differences between the two groups in the number of patients requiring supplemental oxygen. The incidence of airway-related complications such as laryngospasm, croup, sore throat, excessive coughing, and arrhythmias was not different between the two groups. We conclude that the anesthesiologist's preference or surgical requirements may dictate the choice of extubation technique in otherwise healthy children undergoing elective surgery.

To compare a new, clear, unmarked polyvinylchloride (PVC) tracheal tube marketed for use during Neodymium-Yttrium-Aluminum-Garnet (Nd-YAG) laser surgery with a conventional marked PVC tracheal tube. ⋯ The clear, unmarked Sheridan PVC tracheal tube is not recommended for laser airway surgery.
