1. Overview of NPWT Technology

Negative Pressure Wound Therapy (NPWT) is an advanced wound care method widely used in hospitals worldwide for difficult-to-heal wounds, such as chronic ulcers, surgical incisions, traumatic injuries, and infected wounds.

The therapy works by applying controlled negative pressure (vacuum) to the wound bed, helping to remove exudate, reduce edema, enhance blood flow, and stimulate granulation tissue formation, thereby significantly shortening healing time.

Core Components of NPWT

A standard NPWT system includes:

• Foam dressing: applied directly over the wound to distribute suction evenly.

  Vacuum pump and tubing: maintain consistent negative pressure.

  Adhesive drape and exudate canister: ensure a closed, sterile environment.

2. How NPWT Works

Once activated, the negative pressure triggers multiple physiological effects:

• Removes excess fluid and bacteria, reducing infection risk.

  Decreases swelling and increases perfusion, improving oxygen and nutrient delivery.

  Stimulates fibroblast and collagen production, enhancing granulation tissue growth.

  Promotes wound edge contraction, accelerating closure.

3. The Clinical Role of NPWT in Complex Wounds

3.1. Accelerated Healing

Clinical studies show that NPWT can shorten healing time by 30–50% compared to conventional wound dressings, thanks to its ability to promote tissue regeneration.

3.2. Effective Infection Control

Continuous removal of exudate and microbes minimizes biofilm formation – a major cause of chronic non-healing wounds.

3.3. Reduced Pain and Fewer Dressing Changes

Patients typically require dressing changes only every 2–3 days, leading to less pain, lower costs, and minimized tissue trauma.

3.4. Wide Range of Applications

NPWT is beneficial for:

• Post-surgical wounds (orthopedics, neurosurgery, gastrointestinal surgery)

  Chronic ulcers, diabetic foot, pressure sores, and burns

  Elderly or malnourished patients with impaired healing

According to Vietnam’s hospital procurement records, SENSAT.R.A.C™ NPWT foam kits (KCI, USA) are now widely used across major hospitals in various wound sizes (small, medium, large, and bridging types)— highlighting NPWT’s clinical effectiveness and adoption.

4. NPWT Adoption in Vietnam

In Vietnam, NPWT is becoming the gold standard for complex wound management, increasingly applied in both public and private hospitals.

Leading healthcare companies like PHEODORA Co., Ltd. are working to expand access to advanced NPWT solutions, supporting hospitals and clinicians in improving patient outcomes nationwide.

5. Future Perspectives

The integration of NPWT with digital health technologies—such as remote monitoring, smart sensors, and bioactive wound materials—marks the next evolution of personalized, data-driven wound care.

6. Conclusion

Negative Pressure Wound Therapy (NPWT) represents a major advancement in modern wound management, offering superior infection control, faster healing, and better patient comfort.
In Vietnam, companies like PHEODORA are pioneering efforts to bring these life-changing technologies closer to patients, helping redefine standards in surgical and chronic wound care.
