AbstractA 64-year old female requiring prolonged ventilatory support was scheduled for an elective tracheostomy. Anesthesia consisted of surgical infiltration of 1% lidocaine and supplemental isoflurane. The patient was mechanically ventilated with an FIO2 of 1.0. An incision was made over the third and fourth tracheal rings. Opening the trachea with electrocautery resulted in a large leak around the endotracheal tube. The cuff was visualized through the tracheal incision and noted to be deflated. A small bleeder was coagulated on the tracheal ring. At this point, a flash fire occurred rising about one-inch high through the tracheal incision. The surgeon immediately covered the site with his hand. The anesthetist promptly disconnected the anesthesia circuit and removed the endotracheal tube. The surgeon inserted the tracheostomy tube and ventilation resumed. The fire lasted approximately 1-2 seconds. Dexamethasone 10 mg was administered intravenously. End-tidal CO2 and oxygen saturation levels were unchanged. The endotracheal tube was inspected. Approximately one-third to one-half of the cuff was charred. Proper management of an endotracheal tube fire includes stopping ventilation, disconnecting the oxygen source, removing the endotracheal tube, diagnosing injury, administering short-term steroids, administering antibiotics if indicated, providing ventilation and medical support as necessary and monitoring the patient for at least 24 hours. Extreme caution is necessary when using electrocautery in close proximity to an endotracheal tube. If electrocautery is used in close proximity to an endotracheal tube, an FIO2 of 0.3 or less with helium should be used.
