Study Notes

Age Classifications

  • An infant is classified as a child in the first year of life.
  • A young child is classified as a toddler or preschooler, typically between 1-5 years old.
  • A neonate is classified as a newborn in the first 28 days of life.
  • A term neonate is classified as a newborn born between 37-42 weeks of gestation.

Infantile Obstruction

  • Infantile obstruction, also known as pyloric stenosis, is a condition that causes the muscle in the pylorus to thicken, blocking the flow of food from the stomach to the small intestine.
  • Symptoms of infantile obstruction include projectile vomiting, usually after feeding.
  • Environmental factors that may contribute to infantile obstruction include bottle-feeding, as it increases the risk of pyloric stenosis.

Diagnosis and Treatment of Pyloric Stenosis

  • A common sign of dehydration in a case of pyloric stenosis is a decreased urine output.
  • The standard diagnostic technique for pyloric stenosis is an ultrasound examination of the pyloric muscle.
  • The recommended surgical treatment for pyloric stenosis is pyloromyotomy, a surgical incision to divide the overactive muscle fibers.
  • A common postoperative complication of pyloromyotomy is wound infection.

Duodenal Atresia

  • Duodenal atresia occurs in approximately 1 in every 10,000 newborns and infants.
  • Duodenal atresia usually occurs in the second portion of the duodenum.
