Study Notes
Congenital Diaphragmatic Hernia
- Failure of posterior lateral portion of diaphragm before 8 weeks
- Creates opening between peritoneal and pleural pressures
- Treatment involves intubation and nitric oxide for pulmonary hypertension
Tracheoesophageal Fistula
- Esophagus defect connects to trachea
- Diagnosis: inability to pass a catheter to stomach
- Management involves ventilation, upright positioning (30°) to prevent aspiration, and frequent suctioning
Pierre-Robin Syndrome
- Mandibular hypoplasia (underdeveloped jaw)
- Associated with a large tongue and short jaw
- Management: prone positioning, nasotracheal tube, or tracheostomy
Choanal Atresia
- Congenital blockage/absence of nasal passages
- May be unilateral or bilateral
- Diagnosis: inability to pass a suction catheter
- Management: creating a new passage, or intubation/oral airway
Tracheomalacia and Tracheal Stenosis
- Weak or narrowed trachea cartilage
- Causes inspiratory stridor and dyspnea
- Diagnosis: observed during a bronchoscopy
Transient Tachypnea of Newborn (TTNB)
- "Wet lung", a type of respiratory distress
- Excess fluid in lungs, reduced lung compliance
- Management: CPAP, heated high-flow, prone positioning, monitoring lactate
Meconium Aspiration
- Mixture of amniotic fluid and fetal bowel contents
- Causes respiratory distress, inflammation, air leaks, acidosis, persistent pulmonary hypertension
- Diagnosed with a chest X-ray showing a coarse asymmetric pattern
Persistent Pulmonary Hypertension (PPHN)
- Pulmonary vascular resistance remains high after birth
- Shunting through ductus arteriosus and foramen ovale is common
- Diagnosis confirmed via echocardiogram
Bronchopulmonary Dysplasia (BPD)
- Chronic lung disease in infants needing prolonged mechanical ventilation.
- Management involves lowest FiO2 possible, Vt 4-6 ml/kg, permissive hypercapnia
Pneumonia/Pneumonitis
- Bacterial infection in lungs/inflammation
- Causes: alveolar infection, pus formation, RDS
- Leads to inflammation and fluid filling in the lungs
Pulmonary Interstitial Emphysema (PIE)
- Air leakage from lungs into perivascular tissues
- Results from lung over-distention
- Shows "bubbling" near hilar region
- Management: minimal ventilator support, prone positioning
Pulmonary Hypoplasia
- Inadequate development of lungs (cells, airways)
- Usually associated with diaphragmatic hernia
- Common requirement for use of CPAP, prone positioning, or other respiratory support
Hyperbilirubinemia/Jaundice
- Breakdown of hemoglobin results in bilirubin
- Can be either water-soluble or fat-soluble
