Bowel Obstruction Flashcards
the following recording is bowel obstruction from blackboard
notes
gerontologic considerations
for IBD
- second peak at 60s
- physical limitations like walking to the bathroom
- fluid and electrolyte imbalances
what is intestinal obstruction?
content can’t pass through intestines
what is partial?
what is complete?
what is simple?
what is strangulated?
some contents get through
total occlusion ; surgery
intact blood supply
no blood supply
you can also have something called mechanical or nonmechanical obstruction which they mean what?
mechanical
- physical obstruction like hernia, cancer, intussusception
nonmechanical
- reduced or absent peristalsis due to altered neuromuscular paraympathiec innveration
what is a paralytic ileus ?
typically associated with nonmechanical intestinal obstruction
decreased blood flow to the gut
- blood shunts away from the bowel
what is a pseudo-obstuction?
GI motility disorder
- things dont move simply
what is vascular obstruction ?
blood clot
when you have an obstruction distal to the bowel, meaning its at the very end, what happens?
it will empty out and then collapse on itself
what happens in obstruction with a proximal bowel?
distention will occur because its happening before we reach the obstruction
with obstruction we have peristalsis that stops, so it causes patients to (2)
hypotension
hypovolemic shock
due to the decrease blood flow to the area, what happens?
necrosis and then perforation
- bowel content will leak out and causes peritentisis
gangrene of the bowel will cause what?
death and sepsis
where in the bowel the obstruction occurs, it determines fluid and electorlue and acid base imbalances
high (upper duodenum) ?
small intestine ?
large intestine?
decreased HCI acid, metabolic alkalosis
dehydration
gas, fecal not moving
what are the 4 hallmarks of obstruction?
abdominal pain
nausea and vomiting
distention
constipation
