The purpose of this study was to evaluate the usefulness of Trachlight (TL) for nasotracheal intubation and to determine the relationship between the grade of laryngeal view and the subsequent ease of nasotracheal intubation using TL.
Patients requiring nasotracheal intubation were enrolled in this study. Laryngoscopy was performed in all patients under topical anesthesia, with 8% lidocaine spray applied to the supraglottic region and the vocal cords. Glottic visualization during laryngoscopy was assessed using the Cormack and Lehane classification. Patients were allocated to four groups according to this classification. If the TL intubation was unsuccessful after three attempts, intubation was carried out using direct laryngoscopy. Intubation difficulty was assessed by the original 6-point scale and the total intubation time was also recorded.
Trachlight intubation was successful in 89.1% of the 110 patients enrolled in the study. There was no observed correlation between the original 6-point scale and glottic visualization. The total intubation time and the ratio of "unsuccessful" cases were not significantly different among the four groups.
No relationship was found between the ease of nasotracheal intubation using TL and glottic visualization.
本研究旨在评估 Trachlight（TL）在经鼻气管插管中的实用性，并确定喉视图分级与使用 TL 进行经鼻气管插管的后续难易程度之间的关系。
本研究纳入了需要经鼻气管插管的患者。所有患者均在局部麻醉下进行喉镜检查，将 8%利多卡因喷雾剂喷至上咽部和声门。通过 Cormack 和 Lehane 分级评估喉镜检查时的声门可视性。根据该分级，将患者分为四组。如果经过三次尝试后 TL 插管仍不成功，则进行直接喉镜插管。通过原始的 6 分制评估插管难度，并记录总插管时间。
在纳入的 110 例患者中，TL 插管成功 89.1%。原始 6 分制与声门可视性之间未见相关性。四组之间的总插管时间和“失败”病例的比例无显著差异。
使用 TL 进行经鼻气管插管的难易程度与声门可视性之间无明显关系。
