Abstract Background: Nasotracheal intubation (NTI) is frequently performed in oral and maxillofacial surgeries. This study evaluated whether NTI is easier when guided by Disposcope endoscopy or fibreoptic bronchoscopy. Methods: Sixty patients (30 per group) requiring NTI were randomly assigned to undergo fibreoptic bronchoscopy-guided (fibreoptic group) or Disposcope endoscope-guided (Disposcope group) NTI. Then, the NTI time, which was defined as the time from when the fibreoptic bronchoscope or aseptic suction catheter was inserted into the nasal cavity to the time at which the tracheal tube was correctly inserted through the glottis, was recorded. Epistaxis was recorded using direct laryngoscopy five minutes after completing NTI and was scored as one of four grades according to the following modified criteria: no epistaxis, mild epistaxis, moderate epistaxis, and severe epistaxis. Results: The time to complete NTI was significantly longer in the fibreoptic group than that in the Disposcope group (38.4 sec vs 24.1 sec; mean difference, 14.2 sec; 95% confidence interval (CI), 10.4 to 18.1). In addition, mild epistaxis was observed in 8 patients in the fibreoptic group and in 7 patients in the Disposcope group (26.7% vs 23.3%, respectively; relative risk, 1.2; 95% CI, 0.4 to 3.9). No moderate or severe epistaxis occurred in either group. Furthermore, no obvious nasal pain was reported at any time point after extubation in the two groups (P = 0.74). Conclusion: NTI can be completed successfully using either fibreoptic bronchoscopy or a Disposcope endoscope as a guide without any severe complications. However, compared to fibreoptic bronchoscopy, the Disposcope endoscope requires less execution time (the NTI time).

Objective: Magill forceps are frequently used to complete the process of nasotracheal intubation (NTI). We aimed to identify a tube core that could facilitate the NTI process conveniently without Magill forceps. Methods: Sixty patients scheduled for oral and maxillofacial surgeries with no differences between the two groups (30 per group) with regard to demographic data were enrolled in our study. In Group M, the wire-reinforced endotracheal catheter was inserted into the trachea using Magill forceps. However, in Group T, a tube core bent to the physiological curve of the nasal cavity lubricated with aseptic paraffin oil was inserted into the endotracheal catheter, and it was then withdrawn after the endotracheal catheter was advanced through the glottis under direct vision. Results: All NTIs were completed successfully, and no Magill forceps were used in Group T. There was a significant difference in total NTI time between the two groups (Group M, 59.7 (5.1) sec vs Group T, 52.4 (3.1) sec). Mild epistaxis was observed in 6 patients in Group M and 5 patients in Group T (6/30 vs 5/30, respectively). There was no presence of damaged oral tissue or damage to the teeth in either group. Conclusion: We conclude that using the tube core, which is a disposable sterilised stylet, for NTI is a convenient choice.

Abstract Background Clinicians sometimes encounter resistance in advancing a tracheal tube, which is inserted via a nostril, from the nasal cavity into the oropharynx during nasotracheal intubation. The purpose of this study was to investigate the effect of neck extension on advancement of tracheal tubes from the nasal cavity into the oropharynx during nasotracheal intubation. Methods Patients were randomized to the ‘neck extension group (E group)’ or ‘neutral position group (N group)’ for this randomized controlled trial. After induction of anesthesia, a nasal RAE tube was inserted via a nostril. For the E group, an anesthesiologist advanced the tube from the nasal cavity into the oropharynx with the patient’s neck extended. For the N group, an anesthesiologist advanced the tube without neck extension. If the tube was successfully advanced into the oropharynx within two attempts by the same maneuver according to the assigned group, the case was defined as to ‘success.’ We compared the success rate of tube advancement between the two groups. Results Thirty-two patients in the E group and 33 in the N group completed the trial. The success rate of tube passage during the first two attempts was significantly higher in the E group than in the N group (93.8% vs. 60.6%; odds ratio = 9.75, 95% CI = [1.98, 47.94], p = 0.002). Conclusion Neck extension during tube advancement from the nasal cavity to the oropharynx before laryngoscopy could be helpful in nasotracheal intubation.
