Summary

. The optimal position of the endotracheal tube (ETT) within the trachea is the middle third portion, distal to the vocal cords. In addition to clinical assessments, methods such as posteroanterior chest radiography (PA-CXR) and fiberoptic bronchoscopy (FOB) can be used to verify ETT placement.

In our study, we aim to explain the relationship between the most accurate endotracheal tube depth and various formulas by using fiberoptic bronchoscopy, with the help of four different formulas based on age, height, weight, and third finger length.The study further seeks to:

1. To identify the most accurate formula for estimating ETT placement depth in the pediatric population living in Turkey.
2. To reduce the potential complications that may arise from incorrect ETT depth.
3. To determine which formula, when verified by fiberoptic bronchoscopy, is also consistent with auscultation findings-especially in situations where chest radiography or fiberoptic bronchoscopy may not be readily available.
