Neonatal endotracheal tube size

Clinical data underlying recommendations on neonatal endotracheal tube size remain limited. In this multicenter retrospective cohort study, researchers evaluated changes in neonatal endotracheal tube size as a function of weight in infants undergoing tracheal intubation. Changes in size relative to Neonatal Resuscitation Program (NRP) recommendations were tracked within 7 days of intubation. A total of 7,293 intubations were evaluated. Changes in size were observed: 5% with a reduction in tube size, 1.5% with an increase in tube size. Changes in size were more or less frequent depending on the infant's weight.
