Background: The aim of our study was to compare the hemodynamic responses and adverse events associated with nasotracheal intubation (NTI) using a fiberoptic bronchoscope (FOB) and a direct laryngoscope (DLS) in children undergoing general anesthesia for outpatient dental surgery. Methods: Eighty children (aged 5u15 years) were scheduled to undergo outpatient dental surgery under general anesthesia and of these children those who required NTI were included. Results: NTI was significantly longer in the FOB group (P = 0.03). In both groups, systolic blood pressure (SBP) and heart rate (HR) significantly decreased after the induction of anesthesia when compared with the baseline values. SBP was significantly higher in both groups at intubation and 1 and 3 min after intubation when compared with postinduction. SBP significantly increased in the DLS group compared with the FOB group at intubation and 1 min after intubation. HR was significantly increased at intubation and 1 min after intubation in the DLS group compared with the FOB group. Nose bleeding after intubation was significantly more frequent in the DLS group (30%) than in the FOB group (7.5%) (P = 0.034). The incidence of sore throat 24 h after surgery was 20% (8/40) in the DLS group and 2.5% (1/40) in the FOB group (P = 0.014). Conclusions: There are fewer hemodynamic responses and adverse events in the FOB group than in the DLS group; therefore, FOB can be safely used for NTI in children undergoing outpatient dental surgery, and FOB may be more successful than DLS for NTI.
