Role of chest ultrasound in neonatal lung disease: a review of current evidences

Among the common causes of neonatal admission to NICU, respiratory distress is one of the important causes. The neonatal respiratory distress is end result of various pulmonary and non-pulmonary causes. Differentiation of pulmonary causes of respiratory distress is important for the neonatologist as treatment differs with different etiologies. Conventionally, chest X-ray and sometimes CT scan have been used to identify the etiology of respiratory distress but these modalities have several limitations which make their use in NICU doubtful. In recent decades, there has been use of lung ultrasound (LUS) to identify and differentiate the etiologies of respiratory distress. The current available evidence show that LUS has good sensitivity and specificity to identify all the common causes of neonatal distress like respiratory distress syndrome, transient tachypnea of newborn, pneumothorax, and pneumonia. This review will cover the various uses of LUS in neonatal care with current available evidence.
