Abstract: Transient tachypnea of the newborn(TTN) is the most common cause of neonatal dyspnea, and its clinical manifestations are non-specific, which is not easy to distinguish from respiratory distress syndrome, pneumonia, and meconium aspiration  syndrome, etc., and has self-limited characteristics, so missed diagnosis or delayed treatment is commonly seen clinically. In recent years, the number of severe TTN has increased, and ventilator-assisted respiration, even extracorporeal membrane oxygenation, is often used. This paper reviews the pathogenesis, diagnosis and treatment of TTN.
