Perioperative Low-Frequency rTMS for Sleep After Thoracoscopic Lung Resection

Brief Summary

This randomized, double-blind, sham-controlled trial will evaluate whether perioperative low-frequency repetitive transcranial magnetic stimulation (rTMS) can improve early postoperative in-hospital sleep quality in adults undergoing elective thoracoscopic lung resection for primary lung cancer. A total of 220 participants with preoperative sleep impairment will be randomly assigned in a 1:1 ratio to active rTMS or matched sham stimulation. Active rTMS will target the left dorsolateral prefrontal cortex. Five stimulation sessions will be delivered within a 7-day perioperative window: two sessions before surgery, one session after extubation when the participant is clinically stable, and one session on each of postoperative days 1 and 2. The primary outcome is sleep quality measured using the Richards-Campbell Sleep Questionnaire during the first three postoperative inpatient nights. The study will also evaluate wearable-device sleep measures, postoperative pain and analgesic use, recovery, safety, feasibility, and changes in brain activity measured by 64-channel electroencephalography.
