Electro-acupuncture and prochlorperazine effectively reduced postoperative emesis in women undergoing laparoscopy. Electro-acupuncture showed promising results, potentially outperforming transcutaneous electrical nerve stimulation for managing nausea and vomiting.

Area of Science:

  • Anesthesiology
  • Surgical Care
  • Complementary Medicine

Background:

  • Postoperative emesis is a common complication following laparoscopic surgery.
  • Effective antiemetic strategies are crucial for patient recovery and satisfaction.
  • Non-pharmacological interventions are being explored as alternatives or adjuncts to antiemetic drugs.

Purpose of the Study:

  • To compare the efficacy of electro-acupuncture, transcutaneous electrical nerve stimulation (TENS), and prochlorperazine in preventing postoperative emesis.
  • To evaluate the effectiveness of P6 acupoint stimulation for managing nausea and vomiting after outpatient laparoscopy.

Main Methods:

  • A randomized controlled trial involving 100 female patients undergoing outpatient laparoscopy.
  • Four groups received general anesthesia: control, electro-acupuncture at P6, TENS at P6, or intravenous prochlorperazine.

  • Postoperative emesis was recorded within the first 3 hours after surgery.

    • Main Results:

    • The incidence of postoperative emesis was significantly lower in the electro-acupuncture (12%) and prochlorperazine (12%) groups compared to the control group (44%).
    • Transcutaneous electrical nerve stimulation showed a reduced incidence (36%) but was less effective than electro-acupuncture or prochlorperazine.
    • Electro-acupuncture demonstrated comparable efficacy to prochlorperazine in preventing postoperative nausea and vomiting.

    Conclusions:

    • Electro-acupuncture is an effective treatment for reducing postoperative emesis following laparoscopy, comparable to prochlorperazine.
    • Stimulation of the P6 acupoint via electro-acupuncture offers a viable non-pharmacological option for managing postoperative nausea and vomiting.
    • Further research may explore the optimal parameters for TENS at the P6 point to enhance its antiemetic effects.
