Equine 7 Flashcards
D in adults is mostly due to small or large intestine
large (much larger resorptive capacity)
Causes of acute D
Salmonella, clostridia
NSAID toxicity (right dorsal colon)
Carb overload
AB
Cyanothostomiasis
Causes of chronic D (1+ month)
Lawsonia intracellularis
NSAID toxicity
IBD
Liver dx, renal dx
why look for ventral edema in D cases
protein loss
what to check for to assess hypovolaemia
tachycardia
CRT, skin turgor
high PCV would indicate
dehydration
tachycardia + _____ would indicate endotoxaemia
injected MM
How can you check for signs of laminitis
lameness
digital pulses
what on BW would indicate chronic inflammation
low PCV
low RBC
high WBC
high fibrinogen
SI = _____.
LI = diarrhea.
weight loss
tx for acute D
replace fluids
electrolytes
protein
hypertonic vs colloids fluids
hypertonic needs to be followed w isotonic
colloids is better if protein loss
are D cases more often acidotic or alkaline
acidotic
what can be used to control colon inflammation and reduce fluid secretion
COX inhibitors (NSAIDs)
control for endotoxaemia
low dose flunixin
what can be used to promote mucosal repair
sucralfate?
Misoprostol
psyllium mucilloid
what to give for colitis associated DIC
heparin
asparin
what is the one indication for AB w D cases
clostridia (or if suspect clostridia)
which AB for lawsonia
doxycycline
what diet for D
pellet
restrict long roughage
increase oil/calorie
what to do for cyathostomiasis
fenbendazole –> ivermectin
+ dexamethasone
general approach for chronic D
Diet (hay and alfalfa)
Stop NSAID and AB
Caecal transfaunation
Anthelmintics + steroids
Steroids alone if think IBD
low WBC indicate
colon inflammation
endotoxaemia
why might we see high BUN w D
pre-renal azotemia
are chronic D cases low protein
yes. low albumin, but high globulin
what stage of nematode do you look for in feces
larvae (not eggs)
is PCR or culture better for Lawsonia
PCR bc its intracellular
