Many people face a tough night after surgery, unable to rest while their body heals. This study plan looks at a new idea: playing a 40 Hz sound frequency through headphones during the operation to help patients sleep better afterward. The team plans to compare this sound against having no headphones or headphones that play nothing at all. They will watch 342 patients scheduled for laparoscopic gynecological surgery under general anesthesia.
The researchers intend to measure how often patients have sleep trouble on the first night and check scores for anxiety, pain, and nausea. They also plan to see if patients need less pain medicine or spend less time in recovery. However, this document is just a protocol, which means it describes what they will do, not what they found.
Because no results are reported yet, we cannot say if this sound helps or if it causes any harm. The plan lists checking for side effects as a goal, but specific safety data is not available. Until the study is finished and results are published, this remains a question rather than an answer for patients.
