A randomized clinical trial presented at the Anesthesiology 2026 annual meeting finds that patients who wear noise-cancelling headphones during minimally invasive gynecological surgery are less likely to experience postoperative nausea and vomiting (PONV). The study reports a significant reduction in PONV among participants using the headphones during the procedure.
Both outlets link the effect to reduced exposure to surgical noise, suggesting that even under general anaesthesia, environmental sounds in the operating room may contribute to nausea and vomiting afterward. While the New Scientist article focuses broadly on the idea that noise exposure can play a role in PONV and describes headphones as a preventive measure, Medical Xpress emphasizes the randomized trial results in the specific surgical setting studied.
The reports do not indicate changes in anesthesia techniques or medication regimens, but they present headphone use as a potential, low-tech intervention to improve postoperative comfort. Further details on participants, the magnitude of benefit, and secondary outcomes are not included in the provided excerpts.
