Application of cold atmospheric microwave plasma as an adjunct therapy for wound healing in dogs and cats.

BACKGROUND

Cold atmospheric plasma is a novel innovative approach for wound care, and it is currently underrepresented in veterinary medicine.

OBJECTIVES

To investigate the efficacy and safety of using cold atmospheric microwave plasma (CAMP) as an adjunct therapy for wound healing in dogs and cats.

METHODS

Wound healing outcomes were retrospectively analyzed using clinical records of client-owned dogs and cats who were first managed through standard wound care alone (pre-CAMP period) and subsequently via CAMP therapy (CAMP period). The degree of wound healing was estimated based on wound size and a modified wound scoring system.

RESULTS

Of the 27 acute and chronic wounds included in the analysis, 81.48% showed complete healing after the administration of CAMP as an adjunct therapy to standard care. Most wounds achieved complete healing in < 5 weeks. Compared with the pre-CAMP period, the rate of wound healing significantly increased every week in the CAMP period in terms of in wound size (first week, < 0.001; second week, = 0.012; third week, < 0.001) and wound score (first week, < 0.001; second week, < 0.001; third week, = 0.001). No adverse events were noted except for mild discomfort and transient erythema.

CONCLUSIONS

CAMP is a well-tolerated therapeutic option with immense potential to support the treatment of wounds of diverse etiology in small animal practice. Further research is warranted to establish specific criteria for CAMP treatment according to wound characteristics.
