The electrical dynamics of laparoscopic sterilization.

T Engel, F W Harris

    The Journal of Reproductive Medicine
    |July 1, 1975
    PubMed
    Summary

    Preventing bowel burns during laparoscopic sterilization requires low voltage. Coagulating fallopian tubes needs only 100 volts peak, while charring requires 700 volts peak.

    Area of Science:

    • Minimally Invasive Surgery
    • Electrosurgery Principles

    Background:

    • Laparoscopic sterilization is a common procedure.
    • Bowel burns are a potential complication of electrosurgery.

    Purpose of the Study:

    • Determine the minimum voltage for safe laparoscopic sterilization.
    • Investigate electrosurgical parameters to prevent bowel burns.

    Main Methods:

    • Measured electrical resistance of tissues during coagulation.
    • Utilized a "CUT" waveform at varying voltage levels.
    • Evaluated electrosurgical effects on sample tissues and during sterilization.

    Main Results:

    • Coagulation of fallopian tubes is achievable at 100 volts peak.
    • Electrosurgical cutting or fulguration requires approximately 700 volts peak.
    • Tissue electrical resistance changes were documented.

    Conclusions:

    • Low voltage electrosurgery is effective for laparoscopic sterilization.
    • Understanding voltage requirements can minimize risks like bowel burns.
    • Basic electrosurgical principles are crucial for surgical safety.
