Cold-Stored Platelets Could Save Dogs from Life-Threatening Bleeding, Study Finds

A new veterinary study suggests that cold storage can significantly extend the shelf life of platelets used to treat dogs facing life-threatening bleeding. Platelets are a critical blood component that helps clotting, but they are typically stored at room temperature and expire within 5-7 days, limiting their availability in emergency settings. The research, which involved veterinary transfusion medicine experts, found that refrigerated platelets remain functional for up to 14 days, potentially doubling the window for use. This breakthrough could help animal hospitals and emergency clinics stock platelets more reliably, especially in rural or resource-limited areas where fresh supplies are scarce. For dog owners, the findings mean a greater chance that life-saving treatment will be on hand when severe trauma, surgery, or diseases like immune-mediated thrombocytopenia cause dangerous bleeding. The study highlights a practical, low-cost solution that could be adopted quickly by veterinary blood banks. As more clinics adopt cold-stored platelets, survival rates for canine patients with hemorrhage may improve dramatically.
