Hydrogen Peroxide Wound Irrigation in Orthopaedic Surgery

Area of Science:

• Orthopaedic Surgery
• Infectious Disease
• Biomaterials Science

Background:

• Deep hardware infections pose a growing challenge in orthopaedics.
• Hydrogen peroxide (H2O2) is a long-established antiseptic with emerging applications in surgical settings.
• Its efficacy against bacterial colonization and biofilm requires further clinical determination.

Purpose of the Study:

• To evaluate the antiseptic efficacy of hydrogen peroxide in orthopaedic surgery.
• To explore potential synergistic effects of hydrogen peroxide with other common irrigation solutions.
• To define guidelines for the safe and effective application of hydrogen peroxide in debridement and infection management.

Main Methods:

• Review of basic science and clinical research on hydrogen peroxide's antiseptic properties.
• Assessment of its efficacy in reducing bacterial load in orthopaedic infections.
• Evaluation of potential adverse effects, including cytotoxicity and embolic phenomena.
• Development of a protocol for its use in total joint arthroplasty revision surgery.

Main Results:

• Hydrogen peroxide demonstrates significant efficacy against bacteria.
• Potential synergistic effects observed when combined with chlorhexidine and povidone-iodine.
• Concerns identified regarding impaired wound healing, cytotoxicity, and risk of air embolism.
• Specific contraindications identified for partial knee replacements, hemiarthroplasties, native joints, dural compromise, and closed space irrigation.

Conclusions:

• Hydrogen peroxide is an effective agent for infection reduction in orthopaedics.
• Its use should be carefully considered and is not recommended for certain joint procedures due to risks.
• Strict protocols are necessary to mitigate risks, particularly air embolism, when using hydrogen peroxide.
• A specific protocol combining hydrogen peroxide with povidone-iodine and chlorhexidine is proposed for total joint arthroplasty revision.
