Two other simple methods to protect the tracheal cuff of a double-lumen tube.

Coppa and Brodsky (1) described a method to protect the tracheal cuff of a double-lumen tube (DLT) from damage by teeth or by the laryngoscope blade during intubation of the airway. It probably works well, but it seems complicated. Erb (2) described a less difficult method to protect the cuff with a well lubricated teethguard and by lubricating the cuffs of the DLT. There are two other methods to protect the tracheal cuff of a DLT that are simple and require no additional material, help, or effort.
