Application of hyaluronic acid in the healing of non-experimental open wounds: A pilot study on 12 wounds in 10 client-owned dogs

Abstract

Aim:Veterinarians have frequently to deal with wounds to the skin, subcutis, and underlying muscle. The aim was to explore the application of hyaluronic acid (HA)-containing dressing on open skin wounds in dogs. The progress of healing was assessed by wound area reduction and two scoring scales applied in human medicine.Materials and Methods:Ten client-owned dogs with 12 cutaneous open wounds healed by the second intention were included. All wounds were treated using available in commerce HA-containing wound dressing from admission to complete re-epithelialization. At every clinical examination, wound area and scale scoring assessments were performed.Results:After debridement, an increased wound size was obtained while an improvement was determined by both grading systems. The median numbers of return to the clinic for bandage change were 5 times. The median time to complete wound healing was 34.5 days. The mean wound area at day 7, 14, 21, and 28 were, respectively, 90.4%, 47.7%, 22.4%, and 14.8% of the original size (for linear measurement) and 95.5%, 54.4%, 23.10%, and 14.8% of the original size (for software measurement). Regarding wound healing assessment tools, the agreement between two operators was considered high for both scales.Conclusions:HA-containing dressing may be a possible wound treatment for cutaneous open wounds in dogs. The assessment of wound quality using scale scoring system could be useful especially in the 1st week and to direct clinical decision-making process.

Efficacy of chitosan in the treatment of chronic skin lesions in a horse: A case report

“…With regard to the percentage decrease in the lesion area, a regression was observed after 4 weeks. The use of tools to measure the lesion area and assess its progress has a disadvantage: it does not consider the quality of the wound site, and it does not fully reflect changes or reduction in the actual dimensions of the lesion ( Ferrari et al., 2015 ). Despite this regression, the decrease in the percentage of the affected area remained constant and reached 96% in subsequent measurements.…”

Comparison of harmonic blade versus traditional approach in canine patients undergoing spinal decompressive surgery for naturally occurring thoracolumbar disk extrusion

“…While a variety of wound assessment scores have been described to evaluate healing of open wounds, such as pressure sores or granulating wounds [ 35 , 36 ], there appear to be no validated scoring systems assessing incisional healing. The wound assessment score used in this study has not been validated nor was an attempt made to correlate visual inspection with photographs obtained.…”

Moist wound dressing and its application in distant skin flap in cats

“…Wounds on the skin can be caused by injuries, burns, bites [1], chemical irritants, and tumor removal [2]. Skin wounds are usually treated by bringing the two wound edges close together, but if the wound is large in size, it is treated by making a skin flap [1].…”
