Operating room fires in otolaryngology: risk factors and prevention.
OBJECTIVE
The aim of the study was to characterize the causes of operating room (OR) fires in otolaryngology.


METHODS
A questionnaire was designed to elicit the characteristics of OR fires experienced by otolaryngologists. The survey was advertised to 8523 members of the American Academy of Otolaryngology-Head and Neck Surgery.


RESULTS
Three hundred forty-nine questionnaires were completed. Eighty-eight surgeons (25.2%) witnessed at least one OR fire in their career, 10 experienced 2 fires each, and 2 reported 5 fires each. Of 106 reported fires, details were available for 100. The most common ignition sources were an electrosurgical unit (59%), a laser (32%), and a light cord (7%). Twenty-seven percent of fires occurred during endoscopic airway surgery, 24% during oropharyngeal surgery, 23% during cutaneous or transcutaneous surgery of the head and neck, and 18% during tracheostomy; 7% were related to a light cord, and 1% was related to an anesthesia machine. Eighty-one percent of fires occurred while supplemental oxygen was in use. Common fuels included an endotracheal tube (31%), OR drapes/towels (18%), and flash fire (where no substrate burned) (11%). Less common fuels included alcohol-based preparation solution, gauze sponges, patient's hair or skin, electrosurgical unit with retrofitted insulation over the tip, tracheostomy tube, tonsil sponge, suction tubing, a cottonoid pledget, and a red rubber catheter.


CONCLUSIONS
OR fire may occur in a wide variety of clinical settings; endoscopic airway surgery, oropharyngeal surgery, cutaneous surgery, and tracheostomy present the highest risk for otolaryngologists. Electrosurgical devices and lasers are the most likely to produce ignition.
