2.  Vacuum assisted dressing is also known as Negative Pressure Wound Therapy
(NPWT)
 The vacuum-assisted closure (VAC) device was given by Dr Louis
Argenta and Dr Michael Morykwas in 1993.
 Vacuum-assisted cLosure (VAC) therapy- Alternative to the standard forms
of wound management, which incorporates the use of negative pressure
to optimise conditions for wound healing and requires fewer painful
dressing changes.
 The pressure is approximately - (in adult=-70-125mmhg)
(in neonates= -50mmhg)

3.  Promotes granulation tissue.
 Stimulates localized blood flow.
 Reduces bacterial colonization.
 Provides moist wound healing environment.
 Reduces localized edema.
 Enhances epithelial migration.
 Applies negative pressure to uniformly draw wound closed (wound contraction).

4. Materials needed:

 Gloves (sterile or clean)
 Dressing kit
 Canister
 V.A.C. Unit
 Track Pad

14. 1. Acute surgical wounds
2. Pressure ulcers
3. Diabetic wounds
4. Skin grafts
5. Open abdominal wounds
6. Partial thickness burns
7. Pilonidal sinus wounds
8. Necrotizing fasciitis

15. 1. Eschar
2. Presence of necrotic and fibrotic tisme
3. Untreated osteomyelitis
4. Malignant wounds
5. Localized ischemia

16. ➤ Provides more effective therapy.
➤ Reduced frequency of dressing changes.
➤ Reduced bacterial cell count.
➤ Enhanced dermal perfusion.Provision of
closed, moist wound healing
environment.control of odour and exudate.
➤ Reduction in complexity and number of
surgical procedure.

17. • Pain and discomfort when suction is applied initially.
• Allergies to adhesive drape.
• Noise of vac therapy unit.
• If the wound deteriorates after the first dressing
change discontinue vac therapy.
• Fulminant or incipient skin necrosis.
• Excoriation of the skin if foam is not correctly cut to
use.
• Drain require fixation.

18. 1 Explain procedure to patient.
2. Monitor vital signs of patient
3. Arrange all articles properly.
4. Follow aseptic technique.
5. Follow hand hygiene practices.
6. Do wound assessment as it helps to evaluate the
progress of wound healing.

19. • New tool.
• Convert complicated wound into simpler wound.
• Improved efficacy
• Safety outcomes
• Limited cost effectivenesss
• Fewer painful dressing changes
• Smoother transition from hospital to community
