Airway complications from laryngoscopy and panendoscopy

Abstract

Laryngoscopy and panendoscopy can cause airway complications. To determine the risk to the airway from reintubation following general anesthesia in otolaryngology patients, we examined recovery room and anesthesia records at the Albany Veterans Administration Medical Center covering a 10-year period. From this information we determined the incidence of recovery room reintubation and studied airway risk factors associated with otolaryngologic endoscopy. From 1975 to 1984, 10,060 surgical patients were intubated at the Albany VA Medical Center. Only 17 patients (0.17%) required reintubation. Of 1,365 otolaryngology patients intubated during the same period, 324 had laryngoscopy and 302 had panendoscopy. Significantly, four laryngoscopy patients (1.2%) and nine panendoscopy patients (3%) required recovery room intubation. Nine endoscopy patients needed reintubation within 1 hour of extubation. We conclude that the risk of postoperative airway compromise is significantly greater among patients who underwent diagnostic laryngoscopy and panendoscopy than among patients who had general anesthesia for other reasons.
