Prospective cohort study confirms body weight as key predictor of ETT depth in neonates, suggesting stronger clinical guidelines.

To validate nasotracheal endotracheal tube (ETT) insertion depth recommendations for neonates and develop a standardized bedside reference.
Analyzed 497 nasotracheal intubations in a tertiary neonatal intensive care unit from 2017 to 2023.
Used standardized chest radiography to assess tube position post-intubation.
Recorded clinical and biometric parameters and evaluated their associations with insertion depth using LOESS curves and linear regression models.
Body weight showed the strongest association with optimal nasotracheal ETT insertion depth (adjusted R2 = 0.88; RMSE = 0.52).
An evidence-based chart and web-based decision-support tool were developed to aid in bedside estimations.
Findings confirm established reference ranges across various gestational ages and weights.

Tippmann et al. (2026) studied this question.
