Continuous digital hypothermia for prevention and treatment of equine acute laminitis: A practical review.

The research article presents a comprehensive evaluation of Continuous Digital Hypothermia (CDH) as a preventive and early treatment measure for acute laminitis in horses. The researchers review various methods used to administer CDH, their effectiveness, and limitations, emphasizing the need for more efficient approaches.

Understanding Laminitis and CDH

• Laminitis is a severe condition in horses associated with various triggering factors, potentially leading to death.
• Continuous Digital Hypothermia (CDH), which involves cooling the hoof area, has been recommended as a preventive measure and early treatment strategy for this condition.
• CDH’s benefits lie in its ability to modify the inflammatory response, prevent tissue damage, and cause profound vasoconstriction. All these can have desirable protective effects on the animal’s lamellae (the soft, sensitive layer inside the horse’s hoof).

Methods of CDH Application Evaluated

• The research analyzed different methods of providing CDH. They included commercial ice boots, fluid bags filled with cold water or crushed ice, as well as frozen gel packs, and a novel perfused cuff prototype.
• Though some of these methods effectively cooled the hooves to temperatures below the ideal 10 °C mark, they were criticized for being laborious, costly, and over-reliant on an ice source.

Literary Analysis and Findings

• The researchers assessed nineteen published works that evaluated CDH’s effectiveness in preventing and treating laminitis in horses.
• Twelve experimental studies showed CDH could bring multiple positives, such as clinical improvements, immunological and inflammatory modulation, as well as histological protection for the horse’s lamellae.
• The reviewed literature reaffirmed the vital role of CDH in managing different laminitis stages but also illuminated the need for more effective, safe, and user-friendly CDH application strategies that could be deployed both in hospital and ambulatory settings.
