Summary
Positive intra-operative suggestions did not reduce postoperative pain or nausea in patients undergoing total abdominal hysterectomy. This study found no significant benefit from audiotaped suggestions on pain, nausea, or medication use.
Area of Science:
- Anesthesiology
- Psychology
- Surgical Care
Background:
- Patient-centered care increasingly explores non-pharmacological interventions.
- Intra-operative auditory stimulation is a potential method to influence postoperative recovery.
- Previous research on intra-operative suggestions has yielded mixed results.
Purpose of the Study:
- To evaluate the efficacy of positive intra-operative suggestions on postoperative pain.
- To assess the impact of intra-operative suggestions on postoperative nausea and vomiting (PONV).
- To determine if suggestions reduce the need for analgesics and anti-emetics.
Main Methods:
- A double-blind, randomized controlled trial was conducted.
- 140 patients undergoing total abdominal hysterectomy were included.
- Participants were assigned to listen to white noise or positive suggestions (pain, PONV, or both) during surgery.
Main Results:
- No significant reduction in postoperative pain scores was observed in the suggestion groups.
- Positive suggestions did not lead to lower rates of postoperative nausea and vomiting.
- Consumption of morphine and anti-emetic medications remained unchanged across all groups.
Conclusions:
- Intra-operative positive suggestions, as delivered via audiotape, do not appear to be effective in mitigating postoperative pain or nausea following total abdominal hysterectomy.
- The findings suggest that this specific method of auditory suggestion is not a beneficial adjunct for managing common postoperative morbidities in this patient population.
