Abstract
High-frequency subglottic jet ventilation was used in 142 consecutive adults with grade I airways treated with suspension microlaryngoscopy. All cases were managed by the senior anesthesiologist (AP) and the large majority by the senior surgeon (JR), between 2000 and 2002. The laser was used in 30% of cases. There were few complications, none serious, associated with this technique in this series. The subglottic catheter never proved impossible to insert and only needed to be replaced by the supraglottic catheter in two patients because of limitation of visualization of the posterior glottis. The technique was used in a wide variety of surgical pathology from benign hyperfunction-related laryngeal pathology through paralytic vocal fold conditions through papilloma. Advantages and disadvantages over traditional intubation techniques and supraglottic jet ventilation are reviewed, including such issues as ease of intubation/ventilation, surgical exposure/control, maintenance of O2 and CO2 levels, and use in the limited/borderline airway.
