Abstract
The cuffs were inflated with 7ml of air, and then exposed to 50 or 66 percent nitrous oxide for 1 hour to 4 hours.
The cuff volume were increased with relation to concenturation and time related fashion. As cuff volume were increased during nitrous oxide and oxygen anesthesia, overexpansion of cuff may cause upper airway obstruction and trauma on the compressed tracheal wall.
It maybe better to deflate cuff volume intermittently during prolonged anesthesia to avoid overexpansion of cuffs.
