Belfast experience with P6 acupuncture antiemesis.

J W Dundee

    The Ulster Medical Journal
    |April 1, 1990
    PubMed
    Summary

    P6 (Neiguan) acupuncture effectively prevents postoperative sickness. Both invasive and non-invasive methods show antiemetic benefits, with invasive techniques offering longer-lasting relief compared to standard antiemetics.

    Area of Science:

    • Integrative Medicine
    • Clinical Pharmacology
    • Acupuncture Research

    Background:

    • Postoperative nausea and vomiting (PONV) are common complications.
    • Minimizing variables in clinical settings is crucial for evaluating interventions.
    • Standard antiemetics have limitations and side effects.

    Purpose of the Study:

    • To evaluate the prophylactic antiemetic efficacy of P6 (Neiguan) acupuncture.
    • To compare invasive (needling) versus non-invasive (transcutaneous electrical, acupressure) P6 stimulation.
    • To assess the role of P6 acupuncture as an adjunct therapy for chemotherapy-induced nausea and vomiting.

    Main Methods:

    • Controlled clinical trials with reduced variables.
    • Invasive P6 acupuncture (manual and electrical needling).
    • Non-invasive P6 stimulation (transcutaneous electrical stimulation, acupressure).
    • Sham acupuncture point stimulation and post-emetic stimulus administration.
    • Blockade of P6 effect with local anesthesia.

    Main Results:

    • P6 acupuncture demonstrated effective prophylactic antiemetic action in a controlled setting.
    • Invasive and non-invasive P6 stimulation were effective, with invasive methods providing sustained effects.
    • Non-invasive methods were comparable to standard antiemetics in the early postoperative period.
    • Stimulation of a sham point or post-emetic stimulus administration was ineffective.
    • Local anesthesia at P6 blocked the antiemetic effect.
    • P6 acupressure showed moderate efficacy for morning sickness, potentially with a psychological component.
    • P6 acupuncture combined with standard antiemetics aided in reducing chemotherapy-induced nausea and vomiting, with acupressure prolonging effects for 24 hours.

    Conclusions:

    • P6 (Neiguan) acupuncture is a proven prophylactic antiemetic for postoperative sickness.
    • Both invasive and non-invasive P6 stimulation offer therapeutic benefits, with varying durations of action.
    • P6 acupuncture serves as a valuable adjuvant therapy, particularly in managing chemotherapy-induced nausea and vomiting.
