Nasal insertion depths for neonatal intubation.

Aim: Data on the depth of nasal intubation in neonates are rare, although this is the preferred route in some countries. Therefore, recommendations on optimal nasal intubation depths based on gestational age (GA) and weight are desirable.

Methods: We determined the distances between the middle of thoracic vertebrae 2 (T2) and the tip of the endotracheal tube in 116 X-rays from nasally intubated neonates.
