[Transtracheal jet ventilation in the operating room].

Abstract

For the last 40 years transtracheal ventilation has been suggested as a means of bypassing the glottis in emergency in patients unable to be intubated or ventilated by mask. A catheter has been designed to be easily inserted into the crico-thyroid membrane. The outer part of the device, with its dual attachment system, can be connected to conventional resuscitation equipment by its 15 mm male end or to a high-pressure oxygen source by its Luer-Lock fitting. The advantages of transtracheal ventilation are: a clear vision of the operative field, a good gas exchange, an elimination of airway trauma from intubation, a reduction of the hazard of airway fires and a decreased risk of aspiration of blood and debris. Barotrauma is the main danger. However, this method of providing oxygen and/or mechanical ventilation may be extended to the postoperative period, the exit of the insufflated gas mixture being assured at all times.
