The use of NPWT in wound management has increased in recent years as veterinary patients are now being treated for increasingly complex wounds, where veterinary professionals strive for a decreased treatment time, and to help avoid multidrug resistance and complications which can prolong wound closure ( Nolf and Meye-Lindenberg 2016). Best (2014) reported the use of the unit in a slow healing distal extremity - the negative pressure applied to the wound lowers the interstitial pressure, lower than the capillary pressure, which in turn allows the capillaries to reopen and blood flow to the wound to increase.

Enterocutaneous fistulas now, despite early reservations, respond well to NPWT, and orthopaedic traumatic wounds benefit from this method as granulation tissue is evident on hardware, grafts and meshes ( Murphy and Evans, 2012). Less commonly compartment syndromes, for example abdominal or myofascial, are indications for NPWT management ( Nolf and Meye-Lindenberg, 2016). The fluid that is removed during NPWT contains high levels of proteolytic enzymes which if not removed can result in a non-healing wound environment.

Large, contaminated wounds lend themselves to management with NPWT, along with dehiscing surgical wounds ( Murphy and Evans, 2012) degloving injuries and skin avulsions are also indications for use along with chronic non-healing wounds. Publications on the technique date back 16 years, however, only minor changes have been made to the unit itself since it was first used: the unit has been made smaller there is increased safety due to unit alarming changes in the dressing associated and the ability for the unit to remove much more fluid ( Murphy and Evans, 2012). In the author's veterinary practice negative pressure wound therapy (NPWT) is used in a variety of wound care cases. Negative pressure wound therapy: application, indications and is there more we could use it for? This practise has been introduced into the veterinary practice to create an ideal wound healing environment for veterinary patients. NPWT is widely used in humans to aid healing of non-healing wounds, for example debucital ulcers, burns and open fractures. NPWT works by stimulating granulation tissue formation, reducing interstitial oedema and inflammatory cytokines, and improving circulation, all while maintaining a moist wound environment. This method is also referred to as VAC or vacuum-assisted closure. This method of management allows a non-invasive but crucially active and closed system to manage complex wounds by exposing the wound bed to sub-atmospheric pressure. Negative pressure wound therapy (NWPT) is becoming a common tool for wound management in the veterinary practice.
