Estimation of the correct depth of insertion of a tracheal tube (TT) in children is extremely important. Insertion of an excessive length may result in endobronchial intubation while an inadequate length of insertion may lead to accidental extubation.
We reviewed TTs commonly used in paediatric practice and also reviewed recommended guidelines for correct depth of insertion.
Amongst the different brands of TTs used, there was a wide discrepancy in the placement of the intubation depth marker. This is important as the intubation depth marker is often used as a guideline for intubation.
For optimal placement we can rely on various formulae and manufacturers' markings on the TTs. Clinical judgement, however, remains the cornerstone of optimal placement.
准确估计儿童气管导管（TT）的插入深度极为重要。插入过长可能导致支气管内插管，而插入长度不足可能导致意外拔管。
我们回顾了儿科实践中常用的气管导管，并查阅了关于正确插入深度的推荐指南。
在所使用的不同品牌气管导管中，插管深度标记的位置存在很大差异。这一点很重要，因为插管深度标记常被用作插管的指导。
为实现最佳放置，我们可以依靠各种公式以及气管导管上制造商的标记。然而，临床判断仍然是实现最佳放置的基石。
