title: Ultrasonographic Confirmation of Endotracheal Tube Position in Neonates.
abstract: OBJECTIVE
  To compare endotracheal tube tip-to-carina distance obtained by ultrasonography vs. that obtained by chest X-ray in neonates.
  
  
  METHODS
  After endotracheal intubation of 40 neonates, chest X-ray and, within one hour, ultrasonography was obtained for each patient for measurement of endotracheal tube tip-to-carina distance.
  
  
  RESULTS
  Means of endotracheal tube tip-to-carina distances were not significantly different by both modalities (mean difference 0.157 cm, P= 0.06). In addition, an intraclass correlation was observed between them (r2= 0.61, 95% CI= 0.26, 0.79).
  
  
  CONCLUSIONS
  Ultrasonography and chest X-ray are equally accurate for determination of endotracheal tube tip-to-carina in infants. As ultrasonography is more easily available and is safer than X-ray, it may be a better modality for confirming proper placement of endotracheal tube in neonates.
