Equine Colic Types
Hormonal (stress, pregnancy), drugs (most sedatives) and electrolyte changes can alter motility, leading to colic.
Postoperative ileus and exertional ileus
recent abdominal surgery or intense exercise
lack of manure
lower body temp if overheated
performance in hot, humid weather
Guarded for POI; treatment can be prolonged and expensive
good for exertional ileus
lidocaine iv for POI
proper conditioning, avoid overheating for exertional ileus
Proximal duodenitis jejunitis
Inflammation can also lead to ileus. Proximal enteritis is a syndrome characterized by inflammation and edema in the proximal SI, leading to excessive fluid and electrolyte secretion. Both Salmonella and Clostridium have been implicated in proximal enteritis.
Moderate to severe colic
Large amount of reflux, often orange brown with fetid odor
Injected mucous membranes
Depression (less painful)
Rectal palpation – moderate SI distension
Differentials -other causes of ileus, strangulating lipoma
Compared to a physical obstruction, PDJ is more likely to be associated with fever, leukocytosis, less pain, more depression
Abdominocentesis tends to have a mild increase in WBCs and protein; it should not be serosanguinous
Refer for medical management (supportive care, motility stimulants) or surgical decompression
