- May be a complication of LTB
- Thick, purulent secretions result in respiratory distress
- Therapeutic management: humidified oxygen, antipyretics, antibiotics, may require intubation
What is cystic fibrosis?
- Hereditary autosomal recessive trait- if both parents carry, there is 1 in 4 chance
- Basic defect related to abnormal secretions of exocrine glands (mucus producing)
- Lead to obstruction of secretory ducts of pancreas, liver, reproductive organs

How is cystic fibrosis treated and managed?
- newborn: meconium ileus treated user hyperosmolar enemas or surgery
- Older child: aimed at correcting pancreatic deficiency, improving pulmonary function, preventing respiratory disease, maintaining physical activity
- Diet is high in complex carbs and proteins with no fat restriction (may need 1.5-2x cal requirements to promote growth)
- No salt restriction due to loss of salt (increase salt intake in hot weather)
- Pancreatic enzymes (such as pancrealase) to increase digestion and absorption of fat
