    This study introduces a portable fiberoptic fluorometer for quantitative fluorescein measurement. The device accurately predicts flap viability, aiding surgical assessment and patient monitoring.

    Area of Science:

    • Biomedical Engineering
    • Surgical Technology
    • Medical Instrumentation

    Background:

    • Assessing tissue viability is crucial in reconstructive surgery.
    • Current methods for monitoring flap survival can be time-consuming or invasive.
    • Fluorescein dye has shown potential for evaluating tissue perfusion.

    Purpose of the Study:

    • To introduce and evaluate a novel fiberoptic fluorometer for quantitative fluorescein measurement.
    • To assess the instrument's reliability in predicting flap survival and necrosis.
    • To determine the clinical utility of the device in surgical and postoperative settings.

    Main Methods:

    • Intravenous administration of fluorescein dye.
    • Quantitative measurement of tissue fluorescence using a portable fiberoptic fluorometer.

  • Correlation of dye fluorescence index (DFI) with flap survival and necrosis.

    • Main Results:

    • The fiberoptic fluorometer provides accurate, real-time assessment of tissue fluorescence.
    • The dye fluorescence index (DFI) reliably predicts flap viability across various flap types.
    • The instrument is portable, sterilizable, and easy to operate, adding minimal time to procedures.

    Conclusions:

    • The fiberoptic fluorometer is a reliable and practical tool for assessing flap viability.
    • The DFI offers a valuable, non-invasive method for monitoring tissue perfusion and predicting outcomes.
    • This technology can enhance surgical decision-making and improve patient care in flap surgery.
