Positive therapeutic suggestions during neurolept-anesthesia significantly reduced post-operative nausea and vomiting in thyroidectomy patients. This anesthesia technique allowed patients to process suggestions, improving recovery outcomes.

Area of Science:

  • Anesthesiology
  • Psychology
  • Surgical Recovery

Background:

  • Post-operative nausea and vomiting (PONV) are common complications after thyroidectomy.
  • Neurolept-anesthesia, utilizing droperidol-fentanyl-N2O, preserves cognitive functions necessary for processing auditory information.
  • The potential of therapeutic suggestions during anesthesia to influence post-operative outcomes remains an area of investigation.

Purpose of the Study:

  • To investigate the efficacy of positive therapeutic suggestions delivered during neurolept-anesthesia in reducing PONV after thyroidectomy.
  • To determine if patients undergoing thyroidectomy can process auditory suggestions while under general anesthesia.

Main Methods:

  • A double-blind, randomized study involving 100 thyroidectomy patients.

  • One group received positive therapeutic suggestions via tape during neurolept-anesthesia; the control group heard an empty tape.
  • Demographics, anesthetic details, and surgical parameters were comparable between groups.

    • Main Results:

    • The suggestion group experienced significantly less post-operative nausea or vomiting (47.2%) compared to the control group (85.7%).
    • Fewer patients in the suggestion group required anti-emetic medication (30.6%) versus the control group (68.6%).

    Conclusions:

    • Therapeutic suggestions are processed by patients during neurolept-anesthesia.
    • Auditory therapeutic suggestions effectively decrease the incidence of post-operative nausea and vomiting following thyroidectomy.
