Abstract
Background: 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 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 tracheal tube 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nasal cavity lubricated with aseptic liquid paraffin was inserted into the tracheal tube, and the tube core was then withdrawn after the tracheal tube was advanced through the glottis under direct vision.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. Trial registrations: This clinical research was registered at the Chinese Clinical Trial Registry (www.Chictr.org.cn, ChiCTR1900027387).
