    Area of Science:

    • Biomedical Engineering
    • Physiology
    • Medical Technology

    Background:

    • Assessing tissue viability and oxygenation is crucial in various medical fields.
    • Current methods for measuring tissue oxygen tension in biopsies have limitations.

    Purpose of the Study:

    • To describe and validate a new method for evaluating split-skin biopsies using an oxygen electrode.
    • To assess the feasibility of monitoring tissue-oxygen tension in ex vivo biopsy samples.

    Main Methods:

    • A Clark-type polarographic oxygen electrode was utilized.
    • The electrode was placed in controlled contact with split-skin biopsies within a custom-designed, thermostabilized chamber.
    • Tissue-oxygen tension was monitored in fresh and post-mortem tissue at varying temperatures.

    Main Results:

    • The developed method successfully monitored tissue-oxygen tension in split-skin biopsies.
    • Recordings from fresh tissue demonstrated oxygen-tension falls comparable to those obtained with transcutaneous oxygen electrodes in vivo.
    • Post-mortem tissue exhibited different oxygen tension profiles.

    Conclusions:

    • The described method provides a reliable ex vivo approach for evaluating tissue-oxygen tension in split-skin biopsies.
    • This technique offers a valuable tool for research and potentially clinical applications requiring assessment of tissue oxygenation.
    • The findings suggest the method's potential as an alternative or complementary technique to in vivo oxygen measurements.
