How NPWT works positively？
NPWT, which stands for Negative Pressure Wound Therapy, is a medical technique used to promote wound healing. It involves applying controlled negative pressure (suction) to a wound through a sealed dressing system. The primary mechanism of action of NPWT is thought to be the stimulation of wound healing through several interrelated effects:
1. Removal of Excess Fluid:
NPWT helps to remove excess fluid, such as wound exudate and edema, from the wound area. This reduces swelling and helps create an environment that is conducive to healing.
2. Enhanced Blood Flow:
The negative pressure applied by the NPWT device encourages blood flow to the wound area. This increased circulation brings oxygen, nutrients, and immune cells to the wound, which are essential for healing processes.

3. Stimulation of Granulation Tissue:
NPWT promotes the formation of granulation tissue, which is the initial connective tissue that forms at the wound site during healing. This tissue provides a foundation for new blood vessels and supports the migration of healing cells.

4. Cellular Response:
NPWT is believed to stimulate the migration of cells involved in wound healing, such as fibroblasts (which produce collagen and other extracellular matrix components) and macrophages (which play a role in immune response and tissue repair).

5. Reduction of Bacterial Load:
The negative pressure can help reduce the bacterial load in the wound by removing bacteria and inhibiting their growth. The sealed dressing system also helps prevent external contaminants from entering the wound.

6. Closure of Wound Edges:
NPWT can assist in bringing the edges of a wound together, promoting wound closure and reducing the overall wound size. This can be particularly beneficial for large or complex wounds.

7. Promotion of Angiogenesis:
Angiogenesis, the formation of new blood vessels, is crucial for delivering nutrients and oxygen to the healing tissue. The mechanical stress generated by NPWT is thought to stimulate the release of factors that promote angiogenesis.

8. Wound Contraction:
NPWT may facilitate wound contraction, which is the process by which the wound edges move closer together as myofibroblasts contract and pull the tissue inward. This can help reduce the size of the wound and expedite the healing process.

NPWT is typically used under the guidance of medical professionals and is often employed for chronic, non-healing wounds, surgical incisions, and other complex wound scenarios. For more information of NPWT Dressing, please contact Trummed Medical.
