A nasal tube may be put through your horse's nostril and down it's esophagus to check for fluids in the stomach. The vet will also do a manual rectal examination. Any distensions, twists or other abnormalities may be felt deep within the abdominal cavity.
If the veterinarian suspects:
- spasmodic colic an anti spasmodic drug may be administered.
- impaction colic due to a blockage the veterinarian may tube oil or fluid through the nostrils and rectum in an effort to dislodge it.
- intestinal catastrophe such as a twisted intestine he or she will suggest various options including surgery and euthanasia.
