Endotracheal tube displacement is one of the leading causes for airway related complications. Endotracheal tube displacement is much more common in the prone position than in the supine position.
The study population consisted of 120 patients aged between 18-60 years, ASA class 1 and 2, undergoing surgery in the prone position who were randomly allocated into two groups of sixty patients each. The endotracheal tube was secured either with adhesive tape (Group A) or a Thomas tube holder (Group B). The ease of application and removal, effect on caliber of endotracheal tube, amount of displacement of endotracheal tube and also any injuries with either fixation method were studied.
Both groups were comparable with respect to mean time taken for the application of the fixation device, peak airway pressure change after the application of the fixation device in the supine position and after positioning the patient in the prone position and the time taken for removal of the fixation device. Displacement was significantly larger in group A than in group B.
Both methods of fixation of the endotracheal tube are clinically useful in the prone position but the Thomas tube holder is more effective than adhesive tape in preventing displacement of endotracheal tube.
气管内导管移位是气道相关并发症的主要原因之一。气管内导管移位在俯卧位比仰卧位更常见。
研究对象为120例年龄在18至60岁之间、ASA分级为1级和2级、接受俯卧位手术的患者，随机分为两组，每组60例。气管内导管分别用胶带固定（A组）或用托马斯管固定器固定（B组）。研究了固定装置的应用和移除的难易程度、对气管内导管管径的影响、气管内导管的移位量以及两种固定方法的任何损伤情况。
两组在固定装置应用的平均时间、仰卧位应用固定装置后以及患者置于俯卧位后的气道峰值压力变化以及固定装置移除所需时间方面具有可比性。A组的移位明显大于B组。
两种气管内导管固定方法在俯卧位临床上均有用，但托马斯管固定器在防止气管内导管移位方面比胶带更有效。
