- one of the most frequent causes of emergency treatment of horses leading cause of equine mortality |
colic
|
|
|
What causes the abdominal pain of colic?
|
ileus
inflammation |
|
|
___= intestinal obstruction causing colic
___- reaction of a tissue to irritation, injury, or infeciton resulting in pain, swelling, redness, heat ( cause of abdominal pain of colic) |
ileus
inflammation ulcers false colic in many cases cause is unknown |
|
|
What is the importance of preventing colic?
|
one of the most frequent causes of emergency treatment of horses
leading cause of equine mortility |
|
|
Symptoms of colic..
|
looking at abdomen, kicking at abdomen, restlessness, rolling but not shaking when getting up bc painful, sometimes not eating/drinking
|
|
|
What does this do to the pulse rate?
where can you check for the pulse rate? |
increases the pulse rate to greater than 44 BPM
digital pulse- behind leg, near hoof mandibular pulse- under jaw/mandible |
|
|
What happens to the mucous membranes/ gums during colic?
|
longer refill time of color- normal time is 1-2 seconds
normal color=light pink unnatural - bright pink/red- signals impaired blood flow |
|
|
What is going on if the horses gums are gray?
|
going into shock/toxic- contact vet immediately- emergency!!
|
|
|
what are the common causes of colic caused by ileus...
|
increased rate of gas production
impaction displacement/strangulation- twisted bowel enteroliths |
|
|
When there is an ileus colic caused by increase of gas production, what causes this increase?
|
increased gas production --> distention of bowel --> pain--> reduced motility
abrupt change in diet-- switching from low quality forage to high quality switching from feeding no grain, to feeding grain |
|
|
When there is an ileus colic caused by impaction, what causes the impaction?
|
ingested material becomes impacted; can be caused by dehydration, intestinal parasites, sand impaction
|
|
|
When a horse is said to be colicing from ileus from enterolinths- what is happening?
|
enterolinths are intestinal stones found in the large intestine
consists of mineral struvite that surrounds a nidus (cloth, metal, hair, pebbles) -seen in higher rates in Ca, Fl, and LA -diets promoting alkaline pH greater than 7 may contribute |
|
|
colic caused by inflamation is due to ...
|
intestinal parasites, sand, grain overload, blister beetles
|
|
|
How does too much grain cause an inflammation colic?
|
grain is high in starch and is usually digested in the sm intestine
in grain overload, some is digested in the hidgut which causes rapid fermentation and decreased pH (acidic environment) and irritates the intestines |
|
|
What happens in a sand colic from inflammation?
|
sand is ingested and it is very abrasive causing inflammation
|
|
|
What happens in a colic due to blister beetles?
|
blister beetles are associated with alfalfa
-contain cantharidin which irritates the intestines more prominent in mid-summer horses can doe if too many ingested! |
|
|
how do gastric ulcers cause colic?
|
gastric ulcers are erosions of the stomach lining
glandular- acids/mucus produced nonglandular- nothing to protect from acids |
|
|
___= can be found in 40-90% of performance horses and can be seen in foals
-symptoms- loss of body condition -colic/abdominal pain perforation of gut and death diagnosed by endoscopic exam |
gastric ulcers
|
|
|
How do you treat gastric ulcers?
|
the key is to reduce stress by..
increasing turnout time decreasing exercise quiet general environment more forage avoid fasting medical mgt- neutralizing agents to neutralize stomach acid antisecretory agents block production of stomach acid |
|
|
Horses can develop ulcers if they do not eat within ___ hrs..
|
