PYLORIC STENOSIS Flashcards
is the opening between the lower portion of the stomach and the beginning portion of the intestine
Pyloric Sphincter
Hypertrophy or hyperplasia of the muscle surrounding the sphincter occurs
Pyloric Stenosis
Incidence of Pyloric Stenosis in Males
ratio of 1:150
Incidence of Pyloric Stenosis in Females
ration of 1:750
For pyloric stenosis at what weeks of age does infants typically begin to vomit almost immediately after feeding.
around 4 to 6 weeks
Projectile vomit is projecting as much as
3 to 4 ft
Breast or chestfed infants begin have symptoms at
6 weeks
formula-fed infants typically begin having symptoms at closer to
4 weeks of age
Infants present signs of dehydration such as
*dry mucous membrane of the mouth
*sunken fontanelles
*fever
*decreased urine output
*poor skin turgor
*weight loss
may be present because of the excessive loss of chloride from the loss of stomach fluid
Alkalosis
occurs as the body attempts to compensate for the alkalosis
Hypopnea
normal levels of HCO3 content
22 to 28 mEq/L
will diagnose and show a hypertrophied sphincter
Ultrasound
Treatment for Pyloric Stenosis
Surgical or Laparoscopic Correction (pyloromyotomy)
In pyloric stenosis, if electrolyte imbalance, dehydration, and starvation have already occurred, these must be be corrected by administration of
IV fluid,
What type of IV fluid to be given for pyloric stenosis
usually isotonic saline or 5% glucose saline.
an _________ may be used for diagnosis by directly visualizing the hypertrophied sphincter
Endoscopy
an infant who is receiving only IV fluid generally needs a ______ to meet nonnutritive sucking
pacifier
Tetany is verified by
low calcium levels on blood analysis
If tetany is present, what must be administered
IV calcium
pylorus meaning in latin
“gate”
Nursing Diagnosis for Pyloric Stenosis:
*Imbalanced Nutrition: less than body requirements related to inability to absorb food
*Deficient fluid volume related to frequent vomiting
*Risk for Electrolyte Imbalance as related to excessive vomiting
*Risk for Impaired Skin Integrity related to fluid deficit
*Risk for Impaired Oral Mucous Membrane Integrity related to NPO status
decreases muscular contraction and gastrointestinal movement, interrupting the cycle that leads to these symptoms
Atropine Sulfate
what is atropine sulfate
it is a muscarinic acetylcholine inhibitor
