Bovine GI: Abomasal Displacements Flashcards
what ketone level makes a cow hyperketonemic?
> 1.2
what BHBA level would make a cow clinical for hyperketonemia?
> 3.0
why does the rumen being not fully filled lead to a left displace abomasum?
abomasum is allowed to float dorsally towards the left body wall
what is the typical presentation of a left displaced abomasum?
3-20 days in milk
cows>heifers
dull, off feed
decreased production
concurrent disease
what should the pH be in the abomasum?
2-3
how is a cow positioned for minimally invasive surgery for a left displaced abomasum?
dorsal recumbency
what are the two standing surgeries for left displaced abomasum?
right paralumbar fossa omentopexy/pyloropexy
left paralumbar fossa abomasopexy
why are right displaced abomasums more emergent?
potential for torsion
when is the prognosis of a right abomasal volvulus poor?
cow is down/shocky
HR>120 bpm
what should you do for a cow with ketones >3.0?
propylene glycol
B vitamins IM
IV dextrose
what can cause decreased abomasal motility?
hypocalcemia
hyperketonemia
toxemia from concurrent disease
what is the surgery for a left displaced abomasum that is in dorsal recumbency?
right paramedian abomasopexy
what can lead to a right displaced abomasum?
acutely off feed with a full rumen
why is percutaneous surgery not appropriate for a right displaced abomasum?
unsure whether it is torsed or not
what surgery is performed for a right displaced abomasum?
right paralumbar fossa approach
right paramedian can be done
