Advanced Therapies

Beyond Standard Wound Care

For some chronic wounds, standard wound care—cleaning, dressings, offloading, and nutrition optimization—isn't enough to achieve healing. When wounds plateau despite optimal basic care, or when wounds are particularly complex, advanced wound therapies may be the key to unlocking healing potential.

These cutting-edge treatments harness modern medical technology, biological principles, and innovative approaches to address wounds that have resisted conventional treatment. While they're not first-line treatments for all wounds, they can be game-changers for the right patients at the right time.

Negative Pressure Wound Therapy (NPWT)

Also known as vacuum-assisted closure (VAC therapy), NPWT is one of the most widely used advanced wound therapies. A special foam or gauze dressing is placed in the wound, sealed with an airtight film, and connected to a suction device that applies controlled negative pressure.

• Removes excess fluid and drainage from the wound

• Reduces bacterial load and infection risk

• Brings wound edges together, promoting closure

• Stimulates blood flow to the wound bed

• Promotes granulation tissue formation

• Ideal for large wounds, surgical wounds, and wounds with significant drainage

NPWT devices are portable and can be used at home with proper training. Dressings are typically changed every 2–3 days by a healthcare provider.

Hyperbaric Oxygen Therapy (HBOT)

Hyperbaric oxygen therapy involves breathing pure oxygen in a pressurized chamber to dramatically increase oxygen delivery to wounds. The increased atmospheric pressure allows far more oxygen to dissolve in the blood, reaching poorly perfused wound tissues.

• Dramatically increases tissue oxygen levels — up to 10–20 times normal

• Stimulates new blood vessel growth (angiogenesis)

• Enhances white blood cell killing of bacteria

• Promotes growth factor release and tissue repair

• Approved by Medicare for diabetic wounds, radiation injuries, and other chronic wounds

• Typically requires 20–40 sessions, each lasting 90–120 minutes

HBOT is particularly effective for radiation wounds, diabetic foot ulcers with compromised circulation, and wounds that have failed to heal despite standard care.

Bioengineered Skin Substitutes

These advanced products provide biological components to jump-start healing in chronic wounds that lack adequate healing capacity.

• Acellular dermal matrices – Provide scaffolding for tissue ingrowth

• Living skin equivalents – Contain living cells that release growth factors

• Amniotic membrane products – Rich in growth factors and anti-inflammatory proteins

• Platelet-rich plasma (PRP) – Concentrated platelets that release healing growth factors

These therapies are typically used for wounds that have adequate blood supply but simply aren't making the healing 'jump' on their own.

Growth Factor Therapies

Becaplermin gel (Regranex) contains recombinant human platelet-derived growth factor (PDGF) and is FDA-approved for diabetic foot ulcers. It is applied daily to the wound bed to stimulate granulation tissue formation.

Note: Becaplermin carries a black box warning for increased cancer risk with large amounts (more than 3 tubes). Benefits must be weighed against risks and it is used for a limited duration. It works best for wounds with adequate blood supply.

Deciding on Advanced Therapies

Questions to ask when considering advanced treatments:

• Is my wound appropriate? Does my wound type match the approved indications?

• Have I tried adequate standard care first?

• What does the research show for this therapy for my specific wound type?

• Will insurance cover it? Can I commit to the treatment schedule?

• Is my provider experienced with this therapy?

Advanced therapies work best when combined with excellent basic wound care, addressing underlying causes, optimizing nutrition, and patient engagement. Even the most sophisticated advanced therapy cannot overcome poor blood supply, uncontrolled infection, or severe malnutrition.
