A 34 year old male patient underwent emergency operation of tracheal resection and primary end-to-end anastomosis to correct of tracheal stenosis following tracheostomy. On admission, a No. 3 Magill plastic Portex tracheostomy tube had been placed in the previous tracheostomy opening. Stenotic narrowing was noted 4 cm above carina. Despite of severe narrowing of the lesion, anesthetic course was uneventful with nitrous oxide, oxygen and halothane by controlled respiration and serial blood gas analyses. Postoperative courses were also favorable with adequate respiratory cares. It is mandatory to perform serial blood gas analyses for the management of corrective operation on tracheal stenosis.
