AbstractMethods of delivering and monitoring anesthesia during microlaryngeal surgery are constantly evolving. In 1994, Hunsaker and colleagues introduced a laser-safe subglottic Mon-Jet ventilation tube, which has the ability to periodically measure end-tidal carbon dioxide levels. We conducted a retrospective review of 84 consecutive patients who had undergone microlaryngeal procedures with the aid of the Hunsaker Mon-Jet tube. Study parameters included the length of anesthetic induction and recovery times, the duration of surgery, the degree of surgical access to the larynx, and the incidence of anesthetic and surgical complications. We found that anesthetic induction and recovery times with the use of the Mon-Jet tube were comparable to those seen with standard endotracheal intubation. We also observed an apparent reduction in surgical time and a consistent subjective improvement in surgical visualization and access. The complication rate was acceptable, airway control was adequate, and use of the Mon-Jet tube was safe in all patients. We conclude that the Mon-Jet tube is a safe and effective subglottic jet ventilation system and that it has distinct advantages over other methods for both the surgeon and the anesthesiologist.
