Abstract

Abstract: PURPOSE: To explore the influence of fiberbronchoscopic guidance on the incidence and severity of epistaxis during extubation among patients with nasotracheal intubation (NTI). METHODS: This retrospective analysis was conducted among patients who received general anesthesia with NTI and extubated in the postanesthesia care unit between October 2021 to October 2022. According to different intubation approach, the patients were divided into fiberoptic bronchoscope guided group (fiberoptic group), blind insertion and video laryngoscope group (video laryngoscope group). The propensity score matched analysis (PSM) was used to equalize the baseline data of the two groups, and then the incidence and severity of epistaxis during extubation were compared between the two groups. SPSS 26.0 software package was used for data analysis. RESULTS: There was no significant difference in baseline data between the two groups after PSM(P>0.05). The incidence of epistaxis was higher in the video laryngoscope group (38.8%) than in the fiberoptic group (18.4%; relative risk, 0.475; 95%CI: 0.296-0.762; P<0.001). The severity of bleeding was also lower in the video laryngoscope group (Wilcoxon Mann-Whitney odds, 0.644; 95%CI: 0.490-0.832, P=0.001). CONCLUSIONS: Fiberoptic bronchoscope guided NTI reduced the incidence and severity of epistaxis during extubation when compared with NTI performed via blind insertion and video laryngoscope.
