Transient tachypnea of the newborn

Transient tachypnea of the newborn (TTN, TTNB, or "transitory tachypnea of newborn") is a respiratory problem that can be seen in the newborn shortly after delivery. Amongst causes of respiratory distress in term neonates, it is the most common. It consists of a period of rapid breathing (higher than the normal range of 30-60 times per minute). It is likely due to retained lung fluid. It is most often seen in 35+ week gestation babies who are delivered by caesarian section without labor. Usually, this condition resolves over 24–48 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.
