Tracheal Ultrasound for Confirmation of ETT Placement in NICU

Improper placement of the endotracheal tube during intubation can lead to dangerous complications. It has been reported that chest radiography is the gold standard method for validation of endotracheal tube (ET) position . This study will compare the effectiveness of endotracheal tube position obtained by ultrasonography vs that obtained by chest X-ray with two operators an expert and a trainee in preterm neonates. This study will work to the extent that the trainee has the ability to do sonar for premature babies with the same efficiency as an ultrasound specialist.
