Predicting the appropriate size of the uncuffed nasotracheal tube for pediatric patients: a retrospective study

ConclusionsThe formula by height could be most suitable for the selection of size for pediatric nasotracheal intubation. When the predicted tube size was 5.5 or 6.0-mm ID, 0.5  mm smaller size should be chosen at first. In the case of 4.0-mm ID, 0.5 mm larger size should be chosen for first trial.Clinical relevanceThe present data indicate that the selection of nasotracheal tube using the formula by height might be useful.
