NURS 203 Lecture Notes - Duodenal Atresia, Pyloric Stenosis, Peptic Ulcer
Document Summary
Example: male, 3 weeks old and started vomiting non bile stained fluid at 3 wks; palpated the abdomen and felt a knot in ruq and see hyperperistalsis. This is non bile stain fluid at 3 weeks. That would be at birth vomiting of bile stained fluid. So, do not confuse congenital pyloric stenosis (which has no relationship to down"s) with duodenal atresia. It does have multifactorial inheritance; therefore it can be increased in future children. Can see pyloric stenosis, as it has thickened. Non steroidal will block pge2, which is responsible for the mucous barrier of the stomach, and vasodilatation of the vessels, mucous secretion, and secretion of bicarb into the mucous barrier. So, when you take nsaids for a period of time, the whole thing is destroyed. Leads to multiple ulcers and significant blood loss over time. Silver stain (as is pcp, legionella, bartenella hensilai).
