Sonography has gained a broad field of applications in current anesthetic practice. During airway management, it could have an important role, because it allows real-time measurement of anatomical aspects and a functional evaluation with high safety profile. However, assessment of the reliability and precision of these measurements is critical if sonography is used as a clinical diagnostic tool. The aim of the study was to estimate inter-rater and intra-rater reliability of the airway diameter measured by sonography in heathy volunteers.
We conducted a cross-sectional study during 2015 on healthy adult volunteers. Using sonography, transverse internal diameter of subglottic space was measured twice by two blinded sonographers.
Agreement was classified as very good for intra-rater measurements (ICC = 0.84) and good for the inter-rater measurements (ICC = 0.71). The 95% CI of agreement limits for the intra-rater measurements were inferior to those for the inter-rater measurements.
Ultrasound measurement is a reliable and precise method to measure the internal subglottic diameter of the airway. Ultimately, this method may provide clinicians valuable information regarding airway diameter in adults and may help to guide treatment options.
超声检查在当前麻醉实践中已获得广泛的应用领域。在气道管理过程中，它可能发挥重要作用，因为它能够实时测量解剖结构并进行功能评估，且安全性高。然而，如果将超声检查用作临床诊断工具，评估这些测量的可靠性和精确性至关重要。本研究的目的是评估健康志愿者中超声测量气道直径的评分者间和评分者内信度。
我们在2015年对健康成年志愿者进行了一项横断面研究。由两名不知情的超声检查人员使用超声检查对声门下间隙的横向内径进行两次测量。
评分者内测量的一致性被归类为非常好（组内相关系数ICC = 0.84），评分者间测量的一致性被归类为良好（ICC = 0.71）。评分者内测量的一致性界限的95%置信区间低于评分者间测量的一致性界限的95%置信区间。
超声测量是一种可靠且精确的测量气道声门下内径的方法。最终，该方法可能为临床医生提供有关成人气道直径的有价值信息，并可能有助于指导治疗方案的选择。
