Topical oxygen therapy for chronic wounds is not proven to be superior to hyperbaric oxygen therapy. More research is needed to define its mechanisms and clinical efficacy.

Area of Science:

  • Wound healing research
  • Hyperbaric medicine
  • Oxygen therapy

Background:

  • Topical oxygen (TO) is applied to chronic non-healing wounds, often mislabeled as topical hyperbaric oxygen therapy.
  • Proponents claim TO offers advantages over systemic hyperbaric oxygen (HBOT) like lower cost and increased safety.
  • However, the scientific evidence supporting TO's efficacy and mechanisms is limited.

Purpose of the Study:

  • To critically evaluate the current literature on topical oxygen for chronic non-healing wounds.
  • To differentiate TO from systemic hyperbaric oxygen therapy (HBOT).
  • To outline the current policy of the Undersea and Hyperbaric Medical Society regarding TO.

Main Methods:

  • Review of existing literature on topical oxygen application for chronic wounds.

  • Analysis of claims regarding TO's advantages over HBOT.
  • Examination of reported physiological effects and toxicities of TO.
  • Assessment of study designs and evidence quality.

    • Main Results:

    • The literature on TO primarily consists of small case series or non-randomized trials.
    • Mechanisms of action for TO remain undefined and unsubstantiated.
    • Some studies suggest potential cellular toxicities, while others paradoxically report decreased collagen production.
    • The only randomized trial in diabetic foot ulcers indicated a trend toward impaired healing with TO.
    • Contentions of TO superiority over HBOT are not supported by evidence.

    Conclusions:

    • Topical oxygen should not be referred to as hyperbaric oxygen therapy.
    • Mechanisms and results from HBOT studies cannot be directly applied to TO.
    • TO cannot be recommended outside of clinical trials due to insufficient evidence.
    • Further rigorous scientific research, including basic science and clinical trials, is necessary to validate TO's role in wound healing.
