2024年2月5日 · Transient tachypnea is one of the most common causes of neonatal respiratory distress, particularly in term or near term newborns. It is estimated to affect 1-2% of all neonates with an equal gender predilection. Risk factors include cesarean section delivery, maternal diabetes and maternal asthma.

2023年7月4日 · Transient tachypnea of the newborn (TTN) is a benign, self-limited condition that can present in infants of any gestational age shortly after birth. It is caused by a delay in the clearance of fetal lung fluid after birth, which leads to ineffective gas exchange, respiratory distress, and tachypnea.

Transient tachypnea of the newborn (TTN) is due to retained fetal lung fluid. It is a benign self-limiting condition.

2025年3月19日 · Transient Tachypnea of the Newborn (TTN). Frontal radiograph of the chest of a term newborn (left) shows streaky, perihilar linear densities (white circles), indistinctness of the blood vessels and fluid in the minor fissure (black arrow), all signs of increased fluid in the lungs.

Transient Tachypnea of the Newborn (TTN) is also known as wet lung or retained fetal lung liquid. TTN is a diffuse lung disorder that results from delayed clearance of fetal lung fluid after birth, leading to relative surfactant efficacy. It is seen more frequently – but not exclusively – in full term neonates after cesarean delivery.

2023年8月29日 · Transient tachypnea of the newborn (TTN) is a parenchymal lung disorder characterized by pulmonary edema resulting from delayed resorption and clearance of fetal alveolar fluid. It is the most common cause of respiratory distress in late preterm and term infants and is generally a benign, self-limited condition.

Transient tachypnea of the newborn (TTN) is one of the most common causes of perinatal dyspnea and is traditionally diagnosed by chest x-ray. This study aimed to explore the diagnostic value of lung ultrasonography (LUS) for TTN as well as differentiate it from respiratory distress syndrome (RDS) by using LUS.

The CXR will demonstrate the findings of fluid overload with vascular congestion and small pleural effusions. The CXR is nearly always normal by 48-72 hours. TTN on day one of life with mild vascular congestion and small pleural effusions

CXR: normal lung volumes and prominent fine interstitial markings with +/- pleural effusion which resolves in 1-2 days, initially it is radiographically indistinguishable from Group B Streptococcus pneumonia

2016年3月2日 · Transient Tachypnoea of the Newborn (TTN) This condition is also referred to as retained fetal lung fluid or wet-lung syndrome. Normally fluid is cleared from the lungs at, or shortly after, birth by the pulmonary lymphatics and capillaries. In TTN the normal physiological clearance is delayed.
