1. Transient Tachypnea of the Newborn (TTN)?
a. Slow absorption of fetal lung fluid w/resultant tachypnea.
b. The condition more commonly is associated w/C-section deliveries.
c. Self-limited condition usually occurring in a term infant after an uneventful C-section (more commonly) or vaginal birth.
d. It is felt to be caused by slow absorption of fetal lung fluid.
2. Progression of TTN?
a. Infants w/TTN develop respiratory distress shortly after birth w/tachypnea, mild retractions, nasal flaring, and in more severe case grunting and cyanosis.
b. Most infants w/TTN have resolution of their tachypnea in 24-48 hours.
3. Complications of Transient Tachypnea of the Newborn (TTN)?
a. Oxygen saturation drop and supplemental oxygen is required.
b. Rarely does the oxygen requirement exceed 40%.
c. In the rare, more severe cases of TTN consideration for ongoing increased pulmonary
4. Chest radiograph for TTN reveals?
a. Perihilar streaking and fluid in the fissures.
b. Lungs are aerated.
5. Tx of TTN?
a. Supportive care: Supplemental oxygen if necessary.
6. Meconium Aspiration Syndrome?
a. Aspiration of meconium during delivery resulting in respiratory distress.
b. Radiographic findings including hyperinflation w/patchy infiltrates.
c. As meconium may plug small airways, areas of air trapping are often present and may lead to the development of pneumothorax.
7. Respiratory Distress Syndrome?
a. A condition seen in premature infants resulting from surfactant deficiency.
b. Radiographic findings including a characteristic reticulonodular “ground glass” pattern w/air bronchograms and decreased aeration.
8. Presentation of Infants w/RDS?
a. Usually born premature (<34 wks GA).
b. Have a deficiency of surfactant.
c. Shortly after birth they present w/symptoms of respiratory distress, including:
i. Poor oxygenation
ii. Grunting
iii. Retracting
iv. Poor air movement.
9. Radiographic findings w/RDS?
a. Reticulonodular pattern w/air bronchograms
b. Decreased aeration of the lungs!
10. Tx of RDS?
a. Supportive care includes supplemental oxygen as needed to maintain oxygen saturation of 90-95%
b. And
c. IV fluids or nasogastric feeding to maintain hydration as the degree of tachypnea usually precludes oral feedings.
d. Exogenous surfactant is available and is administered by the resuscitation .
11. Congenital Diaphragmatic Hernia (CDH)?
a. The condition of herniation of abdominal contents through the posterolateral foramen of Bochdalek into the thoracic cavity.
b. The incidence is ~1/5000 live births.
12. Extracorporeal Membrane Oxygenation (ECMO)?
a. A system using a modified heart-lung machine utilized in severe pulmonary failure.
b. Cannulation of the carotid artery and jugular vein is required to link the neonate to the system.
13. Tx of a depressed infant w/thick meconium?
a. Endotracheal intubation w/direct suction.
b. Bag-and-mask ventilation or endotracheal intubation w/o suction may increase the volume of meconium aspirated.
14. Signs of Pneumothorax?
a. Excessive light transmission by transillumination on one side with hyperresonance on that side.
b. Infants w/meconium aspiration and respiratory distress are at higher risk for pneumothorax, esp. if high PEEP is used for oxygenation.
