Filling the vacuum: Role of negative pressure wound therapy in open wound management in cats

PRACTICAL RELEVANCE: Open wounds and their treatment present a common challenge in veterinary practice. Approaching 15 years ago negative pressure wound therapy (NPWT) started to be incorporated into clinical veterinary medicine, and its availability is becoming more widespread in Europe and the USA. Use of this therapy has the potential to significantly increase the healing rate of open wounds as well as free skin grafts in small animals, and it has been occasionally described for the management of feline wounds. AIM: This review describes the mechanisms of action of, and indications for, NPWT, and offers recommendations for NPWT specific to feline patients. EVIDENCE BASE: The information presented is based on the current evidence and the author’s clinical experience of the technique gained over the past 12 years. Comparative studies of different treatment options are lacking and, since wound healing in cats and dogs differs, cat-specific studies are especially needed. Well-designed wound healing studies comparing different advanced techniques will improve open wound healing in cats in the future, and potentially allow better understanding of the role of NPWT in this setting.
