Effects of platelet-rich plasma gel on skin healing in surgical wound in horses.

Abstract: To establish a low-cost method to prepare platelet-rich plasma (PRP) and evaluates the potential of platelet derived factors to enhance wound healing in the surgical wounds in equine. Methods: To obtain a PRP gel, calcium gluconate and autologous thrombin were added to platelet-rich plasma. For the tests six saddle horses were used and two surgical incisions were made in each animal. Wounds were treated with PRP gel or untreated. Sequential wound biopsies collected at Treatment 1: at days 5 and 30 and Treatment 2: at days 15 and 45 post wounding permitted comparison of differentiation markers and wound repair. Results: The optimal platelets enrichment over 4.0 time's baseline values was obtained using 300 g for 10 min on the first centrifugation and 640 g for 10 min on the second centrifugation. Conclusions: Wounds treated with PRP gel exhibit more rapid epithelial differentiation and enhanced organization of dermal collagen compared to controls in equine.

This research investigates a cost-effective method for creating a platelet-rich plasma (PRP) gel and examines its impact on surgical wound healing in horses.

Research Methodology

The researchers employed methods to produce a PRP gel, which they later used to evaluate wound healing effectiveness. Specific procedures involved:

  • Adding calcium gluconate and autologous thrombin to platelet-rich plasma in order to create a PRP gel.
  • Using six saddle horses for testing, making two surgical cuts on each animal.
  • Performing tests on wounds treated with PRP gel and untreated wounds for comparison.
  • Collecting wound biopsy samples at two treatment intervals: days 5 and 30 (Treatment 1), and days 15 and 45 post-wounding (Treatment 2).

Results

The results of the study showed that optimal platelet enrichment was achieved by two stages of centrifugation: first at 300 g for 10 minutes, and then at 640 g for 10 minutes. This provides valuable information for the preparation of the PRP gel as it illustrates the centrifugation process necessary for optimal platelet concentration.

Conclusion

The research concluded that wounds treated with PRP gel in horses showed improved healing compared to untreated wounds. The improvements were seen in two main areas:

  • Increased speed in epithelial differentiation. Epithelialization, or the process of forming a new surface layer on the wound to prevent infection and fluid loss, is a key part of wound healing.
  • Enhanced organization of dermal collagen. Collagen, the main structural protein in connective tissues, was better organized in wounds treated with PRP. Proper collagen formation and organization is crucial in wound healing as it lends strength and structure to the healing wound.

In conclusion, the study demonstrates that the PRP gel, a cost-effective wound treatment option in horses, can enhance the healing process when compared to untreated wounds.
