Studies have shown that there are differences in clinical evaluation parameters and difficult intubation rates among different ethnic populations. In our study, we aimed to evaluate the efficacy of upper airway clinical and ultrasonographic measurement methods in Turkish population.
Our study is a single-center, prospective, observational study conducted with 402 patients. All patients underwent clinical airway measurements which are routinely used in pre-anesthetic evaluation. In addition, ultrasonographic anterior neck soft tissue thickness measurements of each patient were made and recorded.
Among the clinical measurements, we found the neck circumference/thyromental distance (TMD) ratio to be significant with a cut-off value of 5.5 and a sensitivity of 92.9% and a specificity of 88.3%, while among the ultrasonographic anterior neck measurements, we found the skin-epiglottic distance to be the most sensitive measurement. We found that there was a positive relationship between the neck circumference/TMD ratio and skin-epiglottis.
In our study, we found that routine measurement methods used in airway examination alone are not sufficient, and measurements that take into account the body proportions of the patients, such as the neck circumference/TMD ratio and the ultrasonographic evaluations are more useful in predicting difficult intubation.
研究表明，不同种族人群在临床评估参数和困难插管率方面存在差异。在我们的研究中，我们旨在评估上气道临床和超声测量方法在土耳其人群中的有效性。
我们的研究是一项在402例患者中进行的单中心、前瞻性观察性研究。所有患者均接受了麻醉前评估中常规使用的临床气道测量。此外，对每位患者进行并记录了超声测量的颈部前软组织厚度。
在临床测量中，我们发现颈围/颏甲距离（TMD）比值具有显著性，截断值为5.5，敏感性为92.9%，特异性为88.3%；而在超声颈部前测量中，我们发现皮肤至会厌距离是最敏感的测量指标。我们发现颈围/TMD比值与皮肤至会厌距离之间存在正相关关系。
在我们的研究中，我们发现仅使用气道检查中的常规测量方法是不够的，考虑患者身体比例的测量方法，如颈围/TMD比值和超声评估，在预测困难插管方面更有用。
