    Study Notes

    • Meconium Aspiration Syndrome (MAS) is a condition that affects newborns with meconium-stained amniotic fluid. Only about 5% of these newborns develop MAS, and it is more common in term infants who have experienced fetal distress in utero or are depressed at birth.

    • MAS is caused by the aspiration of thick, particulate meconium into the lungs, leading to small airway obstruction and respiratory distress. Symptoms include fast breathing, difficulty in breathing, grunting, an overextension of the chest wall, and cyanosis in severe cases.

    • Chest x-ray findings include irregular patchy infiltrates with a hyperextension of the chest wall and a flattening of the diaphragm. Treatment involves suctioning the newborn's airway at the time of delivery and administering antibiotics and steroids.

    • Congenital Pneumonia is an inflammation of the lung parenchyma of the newborn, commonly caused by bacterial infections such as GBS, Strep pneumoniae, and E. coli. Symptoms include respiratory distress and fever, and chest x-ray findings show bilateral diffuse infiltration.

    • Apnea is a common finding in preterm newborns, characterized by a temporary cessation in breathing. Precipitating factors include temperature instability, hypoxemia, and sepsis. Treatment includes evaluating the underlying cause and administering caffeine citrate and theophylline.

    • Hyaline Membrane Disease (RDS) is a condition that occurs primarily in preterm newborns and is caused by a deficiency of surfactant in the lungs. Symptoms include tachypnea, grunting, and cyanosis, and chest x-ray findings show diminished breath sounds and rales at the lung bases.

    • RDS is more common in preterm infants born before 32 weeks GA and in the face of maternal diabetes, multiple gestation, CS delivery, and precipitate delivery. Treatment includes administering surfactant and supportive care.

    • Precipitating factors for apnea in preterm newborns include temperature instability, as a response to the passage of a feeding tube, and sepsis. Apnea of prematurity is a temporary cessation of breathing caused by an immaturity of the central respiratory regulatory center and protective mechanism.

    • Apnea in preterm newborns is rare on the first day of life but may occur in severe preterms and term newborns with neuromuscular disorders. All newborns with apnea should be evaluated for general well-being, feeding tolerance, temperature stability, RBS, PCV, and SPO2. Treatment should be directed at the underlying cause.
