- 3. Modern wound dressings • Most modern wound dressings aid the wound bed to achieve an optimum wound-healing state. • They generally fall into one of four basic categories: 1. Moisture-giving: These dressings donate moisture to the wound bed. This is usually to aid autolytic debridement of sloughy or necrotic tissue, or to provide moisture to a dry wound bed 2. Moisture-absorbing: These dressings absorb excess exudate, to provide a moist rather than a wet wound bed 3. Wound contact layers: These dressings provide a non-adherent layer for wounds with low exudate 4. Interactive: These dressings include those containing antiseptic/antibacterial agents 3
- 4. What is Negative Pressure Wound Therapy? •NPWT does not fit neatly into any of these basic categories •Rather than being a wound dressing, it is an active wound therapy •NPWT is a topical treatment used to promote healing in acute, sub-acute and chronic wounds by applying negative pressure to the wound bed or closed incision 4
- 5. NPWT • Negative pressure wound therapy (NPWT) has become widely adopted over the last 15 years. • There are over 1000 peer-reviewed publications describing the clinical efficacy and safety of NPWT for all wound types that have been published over this period 5
- 6. •Definition: Controlled sub atmospheric pressure in a sealed system that may promote wound healing •Achieved by: •Method to deliver pressure and remove exudate – RENASYS™ Soft Port •Exudate collected in a canister •Wound filler to distribute pressure – Foam or Gauze •Transparent film to achieve seal •Vacuum source (device) for delivery of negative pressure – RENASYS device 6
- 7. Mode of Action - Why does NPWT work? Protects against wound contamination and infection 2 Increased granulation tissue growth 3 More local blood flow 4 Less oedema 5 Control of fluids to maintain a moist wound environment 2 Protects the wound from external contamination1 Improves wound contraction and promotes growth of granulation tissue5-8 Effectively manages wound exudate2-4 Helps to improve perfusion5 Helps reduce tissue oedema9 7
- 8. Mode of Action • Control of fluid and reduction of oedema • A pressure gradient is achieved by creating a closed system and applying sub atmospheric pressure to the wound i.e. negative pressure which “pulls” fluid, materials and cells from the wound bed. • Effect: • Removal of surface wound fluid containing pro-inflammatory mediators such as MMPs, cytokines, proteases and oxygen free radicals • Removal of fluid from within the tissues below the wound surface i.e. reduction of oedema or interstitial fluid 8
- 9. Mode of Action • Improved local blood flow • Wound healing requires increased levels of oxygen and nutrients. Blood flow to the wound bed and surrounding tissue may be decreased due to pressure on the capillaries from inflammation and oedema • Effect: • The negative pressure gradient decreases oedema which decreases the direct pressure on the capillaries allowing for improved blood flow 9
- 10. Mode of Action • Mechanical forces • Specific cells respond to mechanical stretching with an increase in proliferation and migration • Effect: • The exact effects of mechanical stretching requires further research • Negative pressure pulls the wound margins together and reduces the wound volume, this may also assist with improved granulation tissue formation 10
- 11. Mode of Action • Granulation tissue formation • Granulation tissue is dependent on new capillary growth and deposition of connective tissue • Effect: • Each MOA is essential for healing and the combined effects create a wound environment favorable for new tissue formation 11
- 12. Mode of Action • Protects against external contamination and infection • Wound fluid is an excellent medium for bacterial growth. Increased levels of bacteria contribute to delayed and impaired healing in both acute and chronic wounds • Effect: •Removal of wound fluid also removes bacteria from the surface of the wound •Increased blood flow provides higher nutrient and oxygen levels to the wound •Film dressing provides barrier to environmental contaminants 12
- 13. Mode of Action • Pressure gradient fluid shift • Perfusion increased delivery of 02 and nutrients • Mechanical forces stimulatory effect on cells • Granulation tissue formation • Exudate management Each MOA is essential for healing and the combined effects create a wound environment favorable for new tissue formation 13
- 14. Therapeutic benefits of NPWT • Removes unhealthy tissue/cells and maintains clean wound bed • Removes and manages fluid from the wound environment • Reduces oedema • Protects against contamination and infection • Mechanical stretching stimulates cell proliferation and migration • Stimulates granulation tissue formation • Maintains moist wound environment • Protection of wound environment • Decreases the frequency of dressing changes Automated Wound Care 14
- 17. RENASYS™ GO device • RENASYS GO devices are designed to provide NPWT to a closed environment over a wound • The device evacuates the exudate from the wound site into a disposable container • NPWT may promote wound healing via removal of fluids, including irrigation and body fluids, wound exudates and infectious materials • The RENASYS device is intended for use by or on the direction of a trained and licensed healthcare professional 17

- 24. Dressing kit contents and sizes • Dressing kit contents; • RENASYS™ foam • RENASYS Soft Port • Transparent film • Available dressing kit sizes; • Small • Medium • Large • X-large 24
- 25. Dress wound with foam • Cut the foam dressing to fit the size and shape of the wound and place the cut foam into the wound. Avoid over packing. Foam should completely fill the wound • Do not cut the foam directly over the wound bed and after cutting brush to the sides to dislodge any fragments 25
- 26. Apply transparent adhesive film • While holding the transparent film, expose one side of the adhesive backing by removing a single panel, and apply over the wound • Cover the wound filler with transparent adhesive film, removing the remaining panels to seal, then the top stabilisation panel 26
- 27. Apply the RENASYS™ Soft Port • Cut a circular opening (no less than 2cm/0.97” in diameter) in the centre of the film, over the wound filler • Remove any loose transparent film and dispose of away from the wound 27
- 28. Apply the RENASYS™ Soft Port • Remove the adhesive panel from the RENASYS Soft Port dressing and align the port opening directly over the hole in the transparent film 28
- 29. Apply the RENASYS™ Soft Port • Use gentle pressure to anchor the Soft Port to the transparent film • Smooth the dressing down while removing the RENASYS Soft Port’s top stabilisation frame 29
- 30. Activate the RENASYS™ device • Connect the RENASYS Soft Port to the canister tubing by pushing the quick click connectors together • An audible click indicates the connection is secure • Activate the RENASYS device, adjust to the prescribed therapy level • The finished dressing should be firm to the touch and leak-free 30
