  16. 16. 16 Breed There is a consistent finding that Arabian horses are at increased risk of colic, but the reason for this apparently greater risk has not been determined.

  20. 20. 20 The features common to severe colic, and often present to a lesser degree in milder colics, are pain, gastrointestinal dysfunction, intestinal ischemia, endotoxemia and compromised cardiovascular function (shock )
  21. 21. 21 Distension of the gastrointestinal tract stimulation of stretch receptors and pain → inhibits normal gut motility and function → accumulation of ingesta and fluid further destination and pain
  22. 22. 22 Alterations to motility or absorptive function Examples spasmodic colic→ severe contraction of intestine Impaction → blockage of the intestine
  23. 23. 23 Ultimately → most forms of lethal colic involve some degree of ischemia of the intestine because of loss of barrier function

  43. 43. 43  The structure is often compressible, akin to  squeezing a fluid-filled tubular balloon, and slightly moveable. is suggestive of a small-intestinal obstructive lesion or anterior enteritis
  44. 44. 44  Gas and fluid distension of the large colon is evident as large (> 20 cm) taut structures often extending into pelvic canal. Tenial bands are often not palpable.  Impaction is evident as columns of firm ingesta. The most common site is the pelvic flexure

Horses with strangulating lesions have severe clinical signs and usually die within 24 hours of the onset of signs. Horses with non strangulating obstructive lesions : have longer courses, often 48 hours to 1 week
  49. 49. 49  Hematocrit and plasma total protein  blood leukocyte:  Combination of leukopenia and a left shift are consistent with the endotoxemia  Hyperkalemia → in horses with severe acidosis
