Abstract：
BACKGROUND: Endotracheal tube (ETT) malposition is frequent in paediatric intubation. The current recommendations for ETT insertion depths are based on formulae that hold various limitations. This study aimed to develop age-based, weight-based and height-based curve charts and tables for ETT insertion depth recommendations in children.
METHODS: In this retrospective single-centre study, we determined the individual optimal ETT insertion depths in paediatric patients by evaluating postintubation radiographic images. Age-based, weight-based and height-based ETT insertion depth recommendations were developed using regression analysis. We compared the insertion depths predicted by the models with previously published formulae.
RESULTS: Intubations of 167 children (0-17.9 years) were analysed. Best-fit curves generated with logistic regression analysis revealed R2 values between 0.784 and 0.880. The insertion depths predicted by the models corresponded well with published age-based and height-based formulae. However, they demonstrated the unsuitability of weight-related linear formulae to predict ETT depth in children.
CONCLUSIONS: The recommendations developed in this study facilitate a fast and accurate determination of recommended ETT insertion depths in children. Our recommendations provide greater accuracy than previously published formulae and demonstrate that weight-related linear formulae are unsuitable for predicting ETT depth in children.

摘要：
背景：气管内导管（ETT）错位在儿科插管中很常见。对于ETT插入深度的当前建议基于具有各种限制的公式。这项研究旨在开发基于年龄的，儿童ETT插入深度建议的基于体重和基于身高的曲线图和表格。
方法：在这项回顾性单中心研究中，我们通过评估插管后的影像学图像,确定了儿科患者的最佳ETT插入深度.基于年龄,使用回归分析制定了基于体重和基于身高的ETT插入深度建议.我们将模型预测的插入深度与先前发布的公式进行了比较。
结果：分析了167名儿童（0-17.9岁）的插管。用逻辑回归分析生成的最佳拟合曲线显示R2值在0.784和0.880之间。模型预测的插入深度与已发布的基于年龄和基于身高的公式非常吻合。然而,他们证明了体重相关的线性公式不适合预测儿童ETT深度.
结论：本研究中提出的建议有助于快速准确地确定推荐的儿童ETT插入深度。我们的建议比以前发表的公式提供了更高的准确性，并且表明与体重相关的线性公式不适合预测儿童的ETT深度。
