Transient tachypnoea of the newborn (TTN) is a common cause of hospitalisation in the neonatal period, complicating 1 to 1,5 per cent life birth. Predisposing factors are prematurity, birth after C section, especially before the onset of labor. The main factor leading to this condition is a lack of absorption of the fluid contained in the alveolar space resulting in an early respiratory distress which normally resolves in two to five days with oxygen supplementation.
