Percutaneous anaesthesia for taking split skin grafts.

L O Pettersson

    Scandinavian Journal of Plastic and Reconstructive Surgery
    |January 1, 1977
    PubMed
    Summary

    A new topical anesthetic, A2337 containing ketocaine, provides effective percutaneous anesthesia for skin grafting. This method offers a clinically useful alternative to traditional anesthesia techniques with minimal side effects.

    Area of Science:

    • Anesthesiology
    • Dermatology
    • Surgical Innovation

    Background:

    • Percutaneous anesthesia is crucial for procedures like split-skin grafting.
    • Current anesthesia methods may have limitations or side effects.
    • Ketocaine is a local anesthetic with potential for topical application.

    Purpose of the Study:

    • To evaluate two ketocaine compositions (A2174 and A2337) for percutaneous anesthesia in split-skin grafting.
    • To determine the efficacy and optimal application time of the superior composition.
    • To assess the safety and clinical utility of topical ketocaine anesthesia.

    Main Methods:

    • Two ketocaine compositions (A2174, A2337) were applied percutaneously in 50 patients undergoing split-skin grafting.
    • Application time for A2337 was optimized.
    • Efficacy, anesthesia quality, graft healing, and adverse effects were monitored.

    Main Results:

    • Composition A2337 demonstrated superior anesthetic effect compared to A2174.
    • An optimal application time of approximately one hour was determined for A2337.
    • A2337 achieved clinically acceptable anesthesia in all 20 tested patients, with normal graft healing.
    • Erythema and edema were the primary unintended effects.

    Conclusions:

    • Topical ketocaine, specifically composition A2337, provides effective percutaneous anesthesia for split-skin grafting.
    • A2337 offers a clinically viable alternative to existing anesthesia methods.
    • The safety profile, with localized erythema and edema as main side effects, supports its use.
