Activated coagulation test in normal and heparinized ponies and horses.

The research article presents an examination of the Activated Coagulation Test (ACT) in both normal and heparinized adult ponies and horses. Using this test, the study presents findings related to blood clotting times, effectively demonstrating that the ACT can be used for monitoring anticoagulation in medically treated equine animals.

Study Participants and Methodology

• The study involved a cohort of 31 adult horses and 37 adult ponies.
• The Activated Coagulation Test (ACT), a procedure to measure the clotting time of blood, was performed on all these test subjects.
• In addition to using the ACT, the researchers also conducted the Lee-White clotting test on ponies that had been treated with Heparin, a medication that prevents blood clots.

Key Findings

• The average ACT time for all ponies and horses was found to be 2 minutes and 38 seconds, with a standard deviation of 29 seconds.
• The ACT and the Lee-White clotting test in heparinized ponies showed a significant correlation, with a score of 0.95, indicating that the tests produced very similar results with respect to clotting times.
• The researchers were able to successfully monitor anticoagulation in heparinized ponies during long cardiopulmonary bypass procedures using the ACT.

Concluding Insights

• The research highlights the simplicity and reproducibility of the ACT, emphasising it as a technique with a definite endpoint.
• Given its proven effectiveness in this study, the ACT is proposed as an ideal screening test for hemorrhagic diathesis, a condition that makes an individual susceptible to bleeding, in equine animals.

In essence, this research adds significant value to veterinary medicine, elucidating how the ACT can not only be used as a test for blood clotting times in both ponies and horses but also as a monitoring tool in equine animals undergoing anticoagulation treatment.
