Abstract

The aim of the study described here was to evaluate the feasibility and accuracy of measuring endotracheal tube (ETT) depth with ultrasound in adult patients in an intensive care unit (ICU). The distance between the upper margin of the cuff and the upper margin of the aortic arch (Duc-ua) of 67 ICU patients was measured by ultrasound, and the time of measurement was recorded. The level of agreement between the distance between the tip of the ETT and the carina (Dtt-c) measured by ultrasound (U-Dtt-c) and Dtt-c measured by bronchoscopy (B-Dtt-c) was assessed using linear regression and a Bland-Altman plot. There was a significant correlation between B-Dtt-c and U-Dtt-c (r = 0.844, p < 0.001). Also, the Bland-Altman plot revealed strong agreement between B-Dtt-c and U-Dtt-c. The time it took to measure ETT depth by ultrasound was 33.91 ± 5.43 s. In conclusion, bedside ultrasound provides a novel and convenient method for measuring the depth of ETT in ICU patients.

摘要

本研究的目的是评估在重症监护病房（ICU）成年患者中使用超声测量气管内导管（ETT）深度的可行性和准确性。通过超声测量了67例ICU患者的气管导管套囊上缘与主动脉弓上缘之间的距离（Duc-ua），并记录测量时间。使用线性回归和Bland-Altman图评估超声测量的气管导管尖端与隆突之间的距离（U-Dtt-c）和支气管镜测量的Dtt-c之间的一致性水平。B-Dtt-c与U-Dtt-c之间存在显著相关性（r = 0.844，p < 0.001）。此外，Bland-Altman图显示B-Dtt-c与U-Dtt-c之间具有高度一致性。超声测量ETT深度所需的时间为33.91±5.43秒。总之，床旁超声为测量ICU患者的ETT深度提供了一种新颖且便捷的方法。
