Topical oxygen emulsion: a novel wound therapy

Area of Science:

• Wound healing research
• Biomedical engineering
• Dermatology

Background:

• Oxygen is vital for wound repair, influencing phagocytosis and infection rates.
• Increased oxygen tension in wounds can accelerate healing processes.

Purpose of the Study:

• To evaluate the efficacy of a topical oxygen emulsion (TOE) on second-degree burns and partial-thickness wounds.
• To assess the impact of TOE on the rate of wound epithelialization.

Main Methods:

• A double-blind, controlled in vivo study was conducted on pigs with induced second-degree burns and partial-thickness wounds.
• Wounds were treated with TOE, TOE vehicle, or exposed to air.
• Epithelialization was assessed using a salt-split technique.

Main Results:

• Topical oxygen emulsion (TOE) significantly enhanced the rate of epithelialization compared to both vehicle and control groups (P = .001).
• These findings indicate that topical oxygen may be beneficial for acute and burn wound healing.

Conclusions:

• TOE significantly accelerates epithelialization in partial-thickness excisional wounds and second-degree burns.
• This therapy holds potential clinical implications for surgical and burn wound management, promoting earlier barrier function.
• Further clinical studies are warranted to explore TOE's benefits for chronic wounds and surgical incisions.
