pyloric stenosis is suspected what should not be done, ABD/liver palpation, rectal exam, auscultate vascular?

Answer 1

A rectal exam will be unfruitful. There is to my knowledge no particular advantage to auscultate for any vascular sounds, although intense bowel sounds may be present. Reverse peristalic waves are often discribed but infrequently observed.

The most important part of the physical exam is to quiet the infant with a pacifier or a sugar nipple, then carefully palpate for an "olive" along the border of the right lateral rectus muscle. This palpation is becoming a lost art because ultrasound is more sensitive when the diagnosis is first suspected by continuous projectile vomiting.

Answer 2

none of the above. Usually with this condition the MD opts to palpate, rarely auscultate the 4 quadrants of the abdomen, followed by an abdominal ultrasound to outline the level of stenosis.
