What is Negative Pressure Wound Therapy?
Negative pressure wound therapy, also called vacuum-assisted wound closure, refers to wound dressing systems that continuously or intermittently apply subatmospheric pressure to the surface of a wound. Negative pressure wound therapy has become a popular treatment modality for the management of many acute and chronic wounds.
At the wound site, negative pressure wound therapy promotes wound healing and closure by removing excess fluids that can hamper the success of the treatment. Foam dressings used for negative pressure wound therapy are impressively effective dressings that facilitate an equal distribution of pressure across the wound, while reducing the risk of infection. For this reason, and many more, foam dressings are recommended for accompaniment with negative pressure techniques.
Benefits of Negative Pressure Wound Therapy
By creating a controlled negative pressure condition, this type of wound therapy can:
- Accelerate wound healing times,
- Reduce the risk of pathogenic infection,
- Reduce the number of dressing changes, and
- Increase blood flow to the wound area while simultaneously drawing out excess fluids.
