Simulated dimensional compatibility of uncuffed and cuffed tracheal tubes for selective endobronchial intubation in children.

For many age groups of patients requiring selective endobronchial intubation, the lengths of cuffed tracheal tubes, in contrast to those of uncuffed tracheal tubes, were revealed to be critically short for safe taping outside the oral cavity with the cuff placed completely within the right or left mainstem bronchus.
