Transient tachypnea of the newborn
Paediatric and children's diseases
Transient tachypnea of the newborn is a respiratory problem that can be seen in the newborn shortly after delivery. It is caused by retained fetal lung fluid due to impaired clearance mechanisms.[1] It is the most common cause of respiratory distress in term neonates.[2][3] It consists of a period of tachypnea (rapid breathing (higher than the normal range of 30-60 times per minute). Usually, this condition resolves over 24–72 hours. Treatment is supportive and may include supplemental oxygen and antibiotics. The chest x-ray shows hyperinflation of the lungs including prominent pulmonary vascular markings, flattening of the diaphragm, and fluid in the horizontal fissure of the right lung.
