Laminitis treatment: A practical approach
One practitioner's 13-step protocol to help horses suffering from this painful condition
Feb 01, 2011
1. Look at the horse's physical condition, and determine its body score. Does the animal appear to be in pain? Measure its heart rate, and check the horse's conjunctiva for the degree of hyperemia, which indicates pain and blood pressure. Check the digital pulses—are they bounding? Try to turn the horse, and note the degree of difficulty (assuming the horse is standing and able to move).
2. Administer a nonsteroidal anti-inflammatory drug (NSAID). For example, I administer 2 g of phenylbutazone intravenously.3. Obtain dorsopalmar and true lateral soft tissue radiographs of the feet.
4. Start determining your differential diagnoses. Why did the horse develop laminitis? You'll need to figure this out to prevent a relapse.
6. Once the wedge cuffs are secure, reassess the horse's comfort level by prompting movement. If the horse is down, you will need to get it standing to evaluate it with the heel wedge cuffs on.
7. Dispense oral NSAIDs. I typically use a gastric protectant concurrently.
8. Order complete stall rest for one week.
9. Be sure to obtain lateral and dorsopalmar radiographs weekly to monitor for changes.
10. After the week of stall rest, reassess the horse's comfort level. Is it moving normally? Remove one wedge and look at the foot. Is the horse still as comfortable without the wedge? If so, leave it with only one wedge for another week. (This means it's likely a simple Grade I event.) If the horse is not comfortable with one wedge, put the other one back on because the animal has a higher grade of laminitis.
11. After another week, ideally, the horse will be walking and behaving normally. Take the entire cuff off, and walk the horse. Does the animal appear comfortable? If so, congratulations! You've stopped the disease process at a Grade I level. Suggest to the owner that radiographs be taken again in six weeks. (Most of the damage will be apparent at six weeks, allowing you to set up a trimming plan.) If the horse seems uncomfortable without the wedge, put the cuff back on, and try again in another week. (The horse likely has a Grade II laminitic event.) Keep returning at one-week intervals, and try to remove the wedges. Once the horse appears comfortable, you can leave the wedges off and start light hand-walking.
13. Note: Once you've applied cuffs, don't remove them, or you'll engage the deep flexor tendon. If the horse pulls off the wedge cuffs, replace them as soon as possible. Make sure the horse is in a deeply bedded stall, and ensure that the owner knows how to properly apply the cuffs should the need arise.
