| − | **Flunixin meglumine 0.25-1.1mg/kg IV every 6-12 hours

| − | If impaction remains unresolved, pain becomes uncontrollable, or extensive gas distension of the colon occurs, surgery is indicated. Abodominocentesis can be used to monitor the onset of intestinal compromise.(83) At surgery the contents of the colon are evacuated via a pelvic flexure enterotomy.

Description
Impactions are simple obstructions of the gastrointestinal system. In the horse they include:
Prognosis
Good for impactions that resolve medically (95% long term survival in one study) and fair in horses that require surgical intervention (58% long-term survival in the same study) (84)
Prevention
Frequent small feedings(32)
