Just as "there’s more than one way to skin a cat," there is more than one way to repair a horse’s wound, particularly if it’s located on the lower limb. And while many of us might be under the impression that all horse wounds should be stitched closed as soon as possible, this is not always an option. Richard Hackett, DVM, MS, Dipl. ACVS, from the Department of Clinical Sciences in Cornell University’s College of Veterinary Medicine, described what to do in these cases in his presentation at the 2011 American Association of Equine Practitioners convention, held Nov. 18-22 in San Antonio, Texas.
"If there is a high chance that an infection will develop if the wound is sutured closed, due to the presence of foreign material, for example, or if the wound is older and wasn’t presented to the veterinarian early enough to suture, then a technique called ‘delayed wound closure’ could be used," Hackett explained.
Used in situations in which the wound is not presented soon enough or if there is a high risk of infection via the wound, this method–which involves suturing wounds closed four to five days after injury (any sooner than that is considered primary closure)–is helped by the following approaches:
- When cleaning the wound upon discovery, debride the surface of the entire wound to eliminate bacteria, particulate foreign material, and severely damaged tissue and wash the wound with saline under low pressure;
- Use concurrent therapies such as regional limb perfusion with antibiotics, systemic (intravenous or intramuscular) antibiotics and non-steroidal anti-inflamma
