Univent tube provides a new technique for jet ventilation.

HIGH-FREQUENCY jet ventilation (HFJV) is of great advantage during surgical airway resection. When the airway is divided surgically, HFJV can be delivered via small catheters across the field to permit ventilation of the distal airways. This technique has been applied during tracheal reconstruction, tracheal stenosis surgery, sleeve resection of a lung, and management of bronchopleural fistulas. 1 We performed HFJV with a Univent tube (Fuji Systems, Tokyo, Japan), a specialized endotracheal tube incorporating a bronchial blocker in its design to implement one-lung ventilation (OLV). 2 In our patient, the Univent tube was conventionally used initially to block ventilation to the right lung during surgical resection of a tumor mass. Later, the bronchial blocker was repositioned into the left lung, and HFJV was performed through the lumen of the blocker with the balloon deflated while the carinal area was resected and closed. We are unaware of any reports in which the Univent tube has been used specifically for jet ventilation.
