A new tube for single lung ventilation.

A recently developed endotracheal tube with a movable bronchial blocker (Univent tube) was used for single lung ventilation. A total of 50 intubations were undertaken for a wide variety of thoracic procedures. Each case was analyzed with respect to ease or difficulty of intubation, tube dislodgment, efficacy of lung collapse, and adequacy of single lung ventilation. Successful, safe selective intubation was accomplished in all cases.
