Prospective comparison of noninvasive techniques for amputation level selection.

J M Malone, G G Anderson, S G Lalka

    American Journal of Surgery
    |August 1, 1987
    PubMed
    Summary

    Metabolic parameters accurately predict amputation healing, outperforming other tests. Diabetes did not impact healing or metabolic parameter results, aiding in amputation level selection.

    Area of Science:

    • Vascular Surgery
    • Diagnostic Accuracy
    • Metabolic Medicine

    Background:

    • Amputation level selection is critical for successful wound healing.
    • Non-invasive diagnostic tools are needed to improve prediction of healing outcomes.
    • Existing methods for assessing amputation site viability have limitations.

    Purpose of the Study:

    • To prospectively compare the accuracy of various tests in selecting the appropriate amputation level.
    • To evaluate the predictive value of metabolic parameters versus other diagnostic tests for amputation healing.
    • To determine the influence of diabetes mellitus on amputation healing and test accuracy.

    Main Methods:

    • Prospective comparison of multiple diagnostic tests for amputation level selection.

  • Inclusion of transcutaneous oxygen, transcutaneous carbon dioxide, ankle-brachial index, and Doppler pressures.
  • Assessment of metabolic parameters including transcutaneous oxygen, transcutaneous carbon dioxide, and intradermal xenon-133.

    • Main Results:

    • Metabolic parameters demonstrated high statistical accuracy in predicting amputation healing.
    • Other tested methods, including ankle-brachial index and Doppler pressures, lacked statistical reliability.
    • Amputation site healing was not significantly affected by diabetes mellitus.

    Conclusions:

    • Metabolic parameters are reliable indicators for predicting amputation healing.
    • Transcutaneous oxygen and carbon dioxide measurements are valuable tools for amputation level selection.
    • Diabetes mellitus does not confound the predictive accuracy of these metabolic parameters.
