Ultrasonography for Confirmation of Endotracheal Tube Placement in Preterm in Neonatal Intensive Care Unit: Expert Versus Trainee

neonate in the neonatal intensive care unit (NICU) are intubated for different reasons and most of these patients undergo chest X-rays (CXRs) several times during their ICU admission to confirm endotracheal tube (ETT) placement, monitor severity of cardiopulmonary illness, and detect complications of other indwelling devices Although the amount of radiation exposure is minimal with CXRs, exposure to multiple CXRs in NICU patients, especially in preterm, results in accumulated radiation burden over time. This can lead to tissue damage and is associated with an increased risk of malignancy Tracheal ultrasonography is technique for confirmation of proper endotracheal intubation. Potential advantages include detection of both main stem and esophageal intubation and less time to image availability than CXR and less radiation Point of care ultrasound (POCUS) of the anterior neck is increasingly used by emergency physicians and anesthesiologists to detect endotracheal and esophageal intubation. It is more accurate and faster than physical examination and capnography, with adult meta-analyses reporting that it has sensitivities of 93-98%, specificities of 97-98% We will explore effectiveness and reproducibility of tracheal ultrasonography done by in hospital neonatologist trainee in the technique vs the expert radiologist in determination of ET position.
