title: Complications of Venturi jet ventilation during microlaryngeal surgery.
abstract: Microlaryngoscopy for the diagnosis and treatment of laryngeal pathology is a commonly performed procedure in otolaryngology. The use of this technique continues to increase in frequency due to the availability of laser surgery for the management of laryngeal disease. Ventilation during microlaryngoscopy, however, poses a problem as the airway must be shared by the anesthesiologist and the otolaryngologist. Although many techniques of ventilation during microlaryngoscopy are used, the use of high-pressure Venturi jet ventilation, especially during laser surgery, is most frequent. Complications during high-pressure Venturi jet ventilation are uncommon but may occur suddenly and present the surgeon with a life-threatening emergency. Hypoventilation, pneumomediastinum, pneumothorax, severe abdominal distention, and death (directly attributable to various methods of jet ventilation) have been described.
