X ray findings of transient tachypnea of the newborn What is the mechanism behind TTN, and how does it appear radiographically? TTN occurs when amniotic fluid is not fully removed from the lungs during delivery and is more commonly encountered in infants delivered by cesarean section compared to vaginal delivery. Radiographically, TTN appears with increased …

What is the mechanism behind meconium aspiration, and how does it appear radiographically? Perinatal hypoxia may lead to a deep gasping reflex and premature passage of meconium, which combine to cause aspiration. Meconium aspiration may cause lung hyperaeration (sometimes the sole radiographic appearance), scattered areas of atelectasis, and ropelike perihilar opacities with a coarse interstitial …
neonatal diffuse lung diseases • Transient tachypnea of the newborn (TTN). • Congestive heart failure (CHF). • Neonatal pneumonia. • Meconium aspiration. How might other neonatal diffuse lung diseases be differentiated clinically? Neonatal pneumonia and CHF may occur in preterm or term infants, whereas meconium aspiration and TTN are generally diseases of term infants. Neonatal pneumonia occurs more frequently …
Potential complications of Respiratory Distress Syndrome How is RDS treated, and what are the potential complications? Maternal corticosteroids are administered intramuscularly and have been shown to promote surfactant production if preterm delivery is imminent. Exogenous (intratracheal) surfactant administered to the neonate is also beneficial. Infants requiring intubation may develop complications such as air leaks in …

X ray findings of Respiratory Distress Syndrome How does RDS appear radiographically? The radiographic appearance of RDS is a diffuse, symmetric, or patchy ground glass appearance to the lung parenchyma with low lung volumes
What is the difference between RDS and a surfactant dysfunction? RDS is caused by an insufficient amount of surfactant. A surfactant dysfunction may be caused by a mutation in one of the surfactant proteins. Surfactant dysfunctions, such as from mutations in surfactant proteins B, C, or ABCA3, can have a variety of radiologic manifestations in …

What is surfactant, and why is it important? Surfactant is produced by type II pneumocytes. It is a complex substance containing phospholipids and apoproteins, which acts to reduce surface tension and prevent alveolar collapse. Lack of sufficient surfactant in prematurity leads to diffuse microatelectasis and respiratory distress syndrome (RDS).
