transient tachypnea of the newborn
Pronunciation: TRAN-shuhnt tak-ip-NEE-uh
Self-limiting respiratory condition in newborns caused by delayed clearance of fetal lung fluid.
Full Definition
Transient tachypnea of the newborn (TTN) is a benign respiratory disorder that typically occurs in term or near-term infants within the first few hours of life. It results from delayed absorption of fetal lung fluid, leading to temporary respiratory distress characterized by rapid breathing, mild retractions, and grunting. The condition is more common in infants born via cesarean section, as they miss the thoracic compression that occurs during vaginal delivery. TTN usually resolves spontaneously within 24-72 hours as the lung fluid is absorbed through the lymphatic system and pulmonary circulation.
Usage
