Managing Horse Wounds Either Presenting or not with Exuberant Granulation Tissue Using an Innovative Wound Dressing: A Retrospective Non-Controlled Study
Reasons for performing study: Because we used a different innovative protocol for treating equine traumatic wounds, it was decided to analyse retrospectively all the cases treated during the years 2005-2012. Objective: Evaluate the healing performances of traumatic horse wounds, either presenting or not with exuberant granulation tissue (EGT) or exposed bone, using an innovative plant-derived wound dressing and restricting the systemic antibiotic administration only to the first week after trauma. Methods: A retrospective analysis was conducted of all horses (n = 57) presenting with accidental wounds and treated with a plant-derived wound dressing. Classification of Wounds using COW score (Simple Wounds –SW- or Wounds presenting with Exuberant Granulation Tissue – EGT-W), Time To Heal (days), Epithelialisation Rate (cm/days), Health Of Wounds score, Time of First Epithelium appearance (TFE), Cosmetic Aspect of the final Scar (CAS), ease of handling, pain and complications were recorded and evaluated. Results: COW score determined 32 Simple Wounds (SW) with mean size varying from 12,72±6.48 cm2 (< 25 cm2), 50,76± 14,20 cm2 (25 and 100 cm2) to 310,023±132,(> 100cm2) and 25 EGT-Wounds (EGT-W) with mean size varying from 12,90±4,51cm2 (<25 cm2) to 62,76±26,55 cm2 (25 and 100 cm2). The SW healed faster than the EGT-W showing significant differences in the evaluated parameters (58,06±39,44 vs 79±54,32 days) (SW=0,14±0,06 vs EGT-W 0,0742±0,0342 cm/day) and in the TFE (of 7 vs of 18 days). CAS showed no significant differences between SW and EGT-W both presenting high quality of final scar. The dressing was able to keep the EGT formation under control without using surgical resection. Conclusions: This retrospective non-controlled analysis confirmed that equine wound complicated by the EGT have a lower healing performance but the EGT formation can be kept under control with a high quality of final scar. The treatment is simple to use and safe; it enables to reduce the intake of antibiotic and consequently limiting the risk of onset of antibiotic/antimicrobial resistance.
