Subglottic jet ventilation for pediatric microlaryngosurgery: a case report.

A 6-year-old girl with laryngeal papillomatosis underwent ablation of the tumors with Nd-YAG laser under microlaryngosurgery. During the surgery, she was managed with subglottic high-frequency jet ventilation using a stainless steel cannula made from a nerve block needle. It was passed through the light channel of the suspension laryngoscope and firmly affixed to it. There was no hypoxia or barotrauma to the lungs during the surgery. The postoperative course was uneventful.
