Negative Pressure Wound Therapy (NPWT/VAC) is an advanced technique applying continuous or intermittent suction to the wound via a sealed foam dressing connected to a suction device. It revolutionized complex wound treatment.
How It Works:
- Removes excess exudate: Suction pulls fluids, bacteria, and toxins from the wound.
- Stimulates granulation tissue formation: Negative pressure attracts building cells to the wound, accelerating new blood vessel formation.
- Reduces wound size: Suction pulls wound edges toward center, gradually shrinking the wound.
- Reduces swelling: Pulls accumulated fluids from surrounding tissues.
When Used:
- Large deep wounds after surgical debridement.
- Open post-surgical wounds.
- Deep pressure ulcers (Stage 3-4).
- Wound preparation for skin grafting.
Duration:
Typically weeks — dressing changed every 2-3 days. The device stays with the patient at home.
At BEIT TARIQ Center, we provide VAC devices and follow up patients with regular visits for dressing changes and progress monitoring.
