Airtraq has been found to be useful in improving the view of the glottis. However, directing the tube tip into the glottis can be challenging during nasotracheal intubation. This problem gets resolved if the bougie is placed first. The present study was conducted for the evaluation of nasotracheal intubation using a nasal Airtraq laryngoscope with and without a bougie.
Fifty patients of either gender, aged between 18 and 60 years, who belonged to the American Society of Anesthesiologists physical status (PS) I or II, requiring nasotracheal intubation were included. In group I (number () = 25), nasotracheal intubation was performed with a bougie, and in group II ( = 25), it was performed without a bougie. The primary objective was a comparison of the time taken to achieve successful nasotracheal intubation. Secondary objectives were ease of intubation and additional manoeuvres required for intubation.
The mean (± standard deviation) for time for intubation in group I was 59.24 ± 9.98 s and that in group II was 41.00 ± 4.23 s ( = 0.001). Two patients (8%) in group I and ten patients (40%) in group II required additional manoeuvres for intubation ( = 0.008). Twenty-three patients (92%) in group I and 15 patients (60%) in group II had easy intubation ( = 0.030). In group I, no patient had trauma, whereas, in group II, four patients (16%) had trauma ( = 0.030) during intubation.
The time taken for nasotracheal intubation using an Airtraq laryngoscope was more with the use of a bougie as compared to the non-bougie technique. However, bougie-guided intubation was easier with less requirement of additional manoeuvres. In addition, trauma was also significantly less with the bougie technique.
已发现Airtraq喉镜有助于改善声门视野。然而，在经鼻气管插管过程中，将气管导管尖端对准声门可能具有挑战性。如果先放置探条，这个问题就能得到解决。本研究旨在评估使用带探条和不带探条的经鼻Airtraq喉镜进行经鼻气管插管的情况。
纳入50例年龄在18至60岁之间、美国麻醉医师协会身体状况（PS）分级为I或II级、需要经鼻气管插管的患者，性别不限。I组（n = 25）使用探条进行经鼻气管插管，II组（n = 25）不使用探条进行经鼻气管插管。主要目标是比较成功完成经鼻气管插管所需的时间。次要目标是插管的难易程度以及插管所需的额外操作。
I组插管时间的平均值（±标准差）为59.24±9.98秒，II组为41.00±4.23秒（P = 0.001）。I组有2例患者（8%），II组有10例患者（40%）需要额外的插管操作（P = 0.008）。I组有23例患者（92%），II组有15例患者（60%）插管顺利（P = 0.030）。I组无患者出现创伤，而II组有4例患者（16%）在插管过程中出现创伤（P = 0.030）。
与不使用探条的技术相比，使用Airtraq喉镜并使用探条进行经鼻气管插管所需的时间更长。然而，探条引导插管更容易，所需的额外操作更少。此外，探条技术造成的创伤也明显更少。
