Negative Pressure Wound Therapy (NPWT) is increasingly being used as a treatment option for acute, chronic, and surgical wounds, and is also being used within the Community environment. It is a Specialist wound therapy initiated in Secondary care by the Consultant Surgeons, Tissue Viability, and Plastic Surgery Departments, and on occasions in Primary Care by the Community Nursing Teams supported by the Tissue Viability Team.
The product is supplied by Secondary care in the North and East and funded through an agreed mechanism with the NHS Devon CCG.
In the Community authorisation for the use and provision of NPWT is through the Tissue Viability Team, who will give the relevant training and monitor treatment on an ongoing basis. NPWT should only be undertaken by Practitioners who have completed the relevant training and competencies as per their employing organisation guidelines, policies and procedure.
Please note that all NPWT products should be requested via the Tissue Viability Service and not via prescription.
There are a number of different products available from a number of manufacturers, currently the products of choice are either Venturi or Renasys for large, heavily exuding wounds, and PICO for smaller, lighter exuding wounds.
The Venturi Compact product has been designed for use with both gauze and foam wound care sets and has a capacity of 300ml (Lightweight). There is also a channel drain system available.
The Renasys system has two devices, the Renasys go, a portable device for mobile patients, and Renasys EZ plus for additional power and capacity.
The PICO system is a canister free, single use therapy, provided as a seven day kit. The pump is designed to stop working after seven days of continuous use. The pump is attached to a dressing, and the dressing collects the wound exudate, with some moisture able to evaporate through the film of the dressing. The negative pressure generated is a continuous 80mmHg, and the wound must be producing less than 300ml of exudate and be small enough to be covered by one of the PICO dressing sizes suitable for this system.
