Low frequency jet ventilation for stent insertion in a patient with tracheal stenosis

Abstract

Purpose: Evaluate oxygen jet ventilation in a patient with tracheal stenosis undergoing stent insertion. Clinical features: Manual intermittent low frequency oxygen jet ventilation was used during general anesthesia for fibreoptic bronchoscopy and stent insertion in a patient with tracheal stenosis. Oxygen jets were delivered via a Sander's injector adapted to the proximal end of the endotracheal tube on one side, and open to room air on the other side. Adequate oxygenation and carbon dioxide removal were ensured throughout the procedure. Conclusion: Low frequency jet ventilation in a patient with tracheal stenosis provided adequate ventilation as well as a nonobstructed field during fibreoptic bronchoscopy and stent insertion.
