Arterial Insufficiencies: Enhancement of Healing in Selected Problem Wounds (Diabetic Ulcers)
Diabetic foot ulcers are a leading cause of amputation. HBOT can reduce amputation rates by up to 75% when combined with comprehensive wound care.
What are Diabetic Foot Ulcers?
Diabetic foot ulcers are open sores that develop in approximately 15% of patients with diabetes. They typically form on the bottom of the foot and are the leading cause of non-traumatic lower limb amputations.
Diabetes causes poor circulation and nerve damage (neuropathy), which means small injuries may go unnoticed and fail to heal properly. The resulting chronic wounds can become infected and threaten the limb.
Problem wounds also include non-diabetic arterial insufficiency ulcers—wounds that won't heal because of inadequate blood supply to the tissue.
Warning Signs
If you or someone you know is experiencing these symptoms, seek medical attention. Early intervention is critical for many of these conditions.
- Persistent sore or wound on foot or leg
- Wound that doesn't improve after 4 weeks
- Discharge or odor from wound
- Skin color changes around wound
- Increased pain or numbness
- Visible bone or tendon in wound
- Signs of infection (fever, increasing redness, swelling)
Why Diabetic Wounds Fail to Heal
Diabetes impairs healing through multiple mechanisms: reduced blood flow limits oxygen and nutrient delivery, elevated blood sugar impairs white blood cell function, and neuropathy leads to continued trauma to the wound.
Without adequate oxygen, the wound cannot progress through normal healing stages. Collagen formation, bacterial killing, and new blood vessel growth all require oxygen.
Comprehensive Diabetic Wound Care
Healing diabetic wounds requires a multi-disciplinary approach addressing all factors that impair healing. HBOT is one component of an integrated treatment plan.
Offloading
Specialized footwear, casts, or devices that remove pressure from the wound to allow healing.
Debridement
Regular removal of dead tissue and biofilm to create a healthy wound bed for healing.
Advanced Dressings
Specialized wound dressings including collagen, foam, alginates, and antimicrobial options.
Glycemic Control
Optimization of blood sugar levels to support immune function and tissue healing.
Vascular Optimization
Evaluation and treatment of peripheral arterial disease to improve blood flow to the wound.
Nutrition Support
Protein supplementation and nutritional optimization to provide building blocks for healing.
How Hyperbaric Oxygen Therapy Helps
HBOT dramatically increases oxygen delivery to wound tissue, enabling the oxygen-dependent processes of healing. It stimulates new blood vessel formation (angiogenesis), which provides long-term improvement in tissue oxygenation.
Studies show HBOT reduces major amputation rates in diabetic foot ulcers by up to 75% compared to standard care alone.
Key Benefits of HBOT for Diabetic Foot Ulcers
Treatment Protocol
Treatment typically involves 20-40 sessions at 2.0-2.4 ATA for 90 minutes each. Sessions are usually daily, Monday through Friday.
Transcutaneous oxygen measurements (TCOM) help determine if HBOT will be beneficial and monitor treatment response. HBOT is most effective as part of comprehensive wound care including offloading, infection control, and vascular optimization.
Related Conditions
Necrotizing Fasciitis
Necrotizing fasciitis ('flesh-eating bacteria') is rapidly fatal without aggressive treatment. HBOT is a critical adjunct to surgical debridement.
Bone Infection
Chronic bone infections that fail to respond to surgery and antibiotics may respond to HBOT by enhancing oxygen delivery to infected bone.
