This test can be helpful and is routinely carried out if the colic persists or more serious
problems are suspected. However, a normal peritoneal tap does not rule out the possibility of
VetBooks.ir a serious problem developing. The cell count, lactate, protein content and specific gravity
may also be measured. These are often normal in medical colics but increased in horses with
inflamed and ischaemic intestines.
If peritonitis is suspected, the fluid will be cultured to try and identify the bacteria
involved and their antibiotic sensitivity.
BLOOD TESTS
A number of blood tests may be taken. The ones most commonly used to monitor a patient
are:
• packed cell volume (PCV)
• white cell count
• total protein
• lactate.
ULTRASONOGRAPHY
Ultrasonography can be helpful for identifying some small intestinal problems including
distension, obstruction and lack of motility.
HISTORY
The history may provide clues to the possible cause of the colic. The vet will want to know:
• the age of the horse
• if the horse has had colic before
• when the first problems were observed
• what were the first signs
• if the horse has had any recent dietary changes
• when it was last treated for worms and which preparation was used
• if any dental problems are present and when the teeth were last inspected
• if the horse is taking medication for any other condition
• if the stable management/bedding has been changed
• the soil type in the pasture
• if the horse crib bites or wind sucks.
