Summary

Limited research on gas gangrene treatments shows no clear benefit for Chinese herbs or hyperbaric oxygen therapy. More rigorous trials are needed to determine effective and safe interventions for this severe bacterial infection.

Area of Science:

  • Infectious Diseases
  • Bacteriology
  • Clinical Medicine

Background:

  • Gas gangrene is a severe, rapidly progressing bacterial infection with high amputation rates and poor prognosis.
  • Effective treatment requires early diagnosis and comprehensive interventions, including wound debridement, antibiotics, and hyperbaric oxygen therapy.
  • The efficacy and safety of current gas gangrene treatments remain largely unconfirmed.

Purpose of the Study:

  • To evaluate the efficacy and safety of interventions for gas gangrene.
  • To compare different treatment strategies against each other or no intervention.

Main Methods:

  • A systematic search of multiple databases (e.g., Cochrane, MEDLINE, EMBASE) was conducted for relevant randomized controlled trials (RCTs) and quasi-RCTs.
  • Two independent reviewers selected studies, extracted data, and assessed risk of bias.

  • Due to limited studies and heterogeneity, a narrative review was performed instead of a meta-analysis.

    • Main Results:

    • Two RCTs involving 90 participants were included, assessing 'cure rate' differently.
    • One trial suggested a potential benefit of Chinese herbs alongside standard treatment (Risk Ratio [RR] 3.08, 95% CI 1.00 to 9.46), but with very low quality evidence.
    • Another trial found no difference between topical and systemic hyperbaric oxygen therapy (HBOT) when added to standard treatment (RR 1.10, 95% CI 0.25 to 4.84), also with very low quality evidence. Primary outcomes like quality of life, amputation, and death were not reported.

    Conclusions:

    • Re-analysis indicated no demonstrated benefit of additional Chinese herbs or topical HBOT for gas gangrene cure rates.
    • The current evidence is insufficient to determine the safety and effectiveness of gas gangrene interventions.
    • Further high-quality RCTs focusing on core treatments and key clinical outcomes are essential.
