Background  Airway management is a part of routine anesthetic procedures; however, serious complications, including hypoxia and death, are known to occur in cases of difficult airways. Therefore, alternative techniques such as fiberoptic bronchoscope-assisted intubation (FOB intubation) should be considered, although this method requires more time and offers a limited visual field than does intubation with a direct laryngoscope. Oxygen insufflation through the working channel during FOB intubation could minimize the risk of desaturation and improve the visual field. Therefore, the aim of this prospective randomized controlled study was to evaluate the utility and safety of oxygen insufflation through the working channel during FOB intubation in apneic patients.    Methods  Thirty-six patients were randomly allocated to an N group (no oxygen insufflation) or an O group (oxygen insufflation). After preoxygenation, FOB intubation was performed with (O group) or without (N group) oxygen insufflation in apneic patients. The primary outcome was the velocity of decrease in the partial pressure of oxygen (PaO 2 ) during FOB intubation (V PaO2 , mmHg/sec) defined as the difference of PaO 2  before and after intubation divided by the time to intubation. The secondary outcomes included the success rate for FOB intubation, time to intubation, visual field during FOB intubation, findings of arterial blood gas analysis, and occurrence of FOB intubation-related complications.    Results  We found that V PaO2  was significantly greater in the N group than in the O group (1.0 ± 0.4 vs. 0.4 ± 0.4;  p  < 0.001), while the visual field was similar between groups. There were no significant intergroup differences in the secondary outcomes.    Conclusions  These findings suggest that oxygen insufflation through the working channel during FOB intubation aids in extending the apneic window during the procedure.
