Transtracheal High-frequency Jet Ventilation using a Two-lumen Central Venous Catheter for Laryngomicrosurgery: A case report

Abstract

A 33 year old female patient was scheduled for laser laryngomicrosurgery to remove a polyp arising from the posterior one third of the vocal cord.A double lumen central venous catheter was inserted through the cricothyroid membrane and transtracheal high frequency jet ventilation was performed via the distal lumen.The proximal lumen was connected to a capnography monitor, enabling breath by breath monitoring of PETCO2.The surgery was successfully completed, and the patient was discharged from the post anesthesia care unit (PACU) three hours after surgery without any complication.
