These case reports describe the authors' experiences with ten cases in which an amored endotracheal tube (ETT) was partially inserted through a nostril into the nasopharynx to relieve the upper airway obstruction and respiratory depression during monitored anesthesia care. The amored ETT was connected to the semiclosed circuit system of an anesthesia machine equipped with an end-tidal CO2 monitor; assisted positive ventilation was applied if needed. This manuever enabled airway obstruction relief, the oxygen saturation to be increased immediately, and the respiratory pattern to be monitored continuously, but it did not interfere with the surgical procedure. Therefore, we introduce this universally available amored ETT for airway maintenance without interfering with surgical procedure such as facial chemical peeling.
