Equine 5 Flashcards
trending indications for surgery for colic
Severe continuous pain, no analgesia response
Progressively rising pulse
Progressive CV collapse (SI distension)
before sending off for referral, do what?
Decompress
Analgesia (if far)
Rug + leg bandages
general management of simple colic (not surger)
House on deep inedible bedding
Remove feed until passes several piles
Hand walk every 2-3 hours
Free access to water
what effects might drugs have on colic cases
Reduced GI motility
Masks pain
analgesics for colic cases
NSAIDs (don’t change motility)
pro and con for phenylbutazone c.f. flunixin
pro: less likley to mask CV signs of endotoxaemia
con: not licensed for colic use
side effects of alpha 2 agonists
reduced GI motility
bradycardia
buscopan
spasmolytic
which main laxatives do we use
isotonic fluids (NG tube)
oral MgS
when to use liquid paraffin as laxative
when suspect you need lubrication over softening
purpose for IV fluids in colic cases
severe dehydration/shock
which portion is most prone to GI ulcers
squamous portion (no protection against acid)
*worse in high intensity training bc pushes acid up
how does GI ulcer signs differ
less pawing/signs of visceral pains.
mostly just grumpy and inappitant
tx for GI ulcers
PPI (omeprazole)
sucralfate
gastric dilatation is usually secondary to ____ obstruction
distal SI
things that can lead to gastric dilation
dental dx
poor roughage
poor gastric emptying
highly fermentable foods
reflux in NG intubation points to
gastric dilation
tx for gastric dilation
use carbonated drink to lavage
anterior enteritis leads to colic bc
decreased motility
increased fluid secretion
what is “spasmodic colic”
most commonly reported (rapid onset, no rectal findings, goes away w NSAIDs/buscopan)
tx for tympanic colic
analgesia and exercise
Large colon intraluminal obstructive is usually at pelvic flexure. tx?
Restrict feed
Analgesia
Laxative
IV fluids
Dx for small colon impaction.
distended abdomen. reduced fecal output.
*cannot tell via rectal.
why is enema not common in horses?
risk of bowel perforation
Ileal impactions (worms) dx?
palpate SI distension.
slow progressive CV time, not endotoxaemic.
reflux
type 1 vs type 2 caecal impaction
Type 1 - dry ingesta fills caecum
Type 2* - impaired caecal outflow (impaired motility) *prone to rupture
contributing factors to colon displacement
older, recent foaling, abrupt change in feed
tx options for LDDC Left Dorsal Displacement of the Colon
- starve + analgesia
- phenylephrine + exercise
- laparscopic correction
what does phenylephrine do for LDDC
splenic contraction
RDDC: pelvic flexure moves between
caecum and body wall
degree of colic in RDDC depends on
degree of torsion
