Brief Summary

Video-assisted thoracoscopic surgery (VATS) is the mainstream minimally invasive procedure in thoracic surgery; However, the high-stress state during the perioperative period and severe postoperative pain often lead to significant disruption of patients' sleep patterns, thereby exacerbating postoperative pain sensitisation and delaying early recovery. Traditional sleep-inducing drugs, primarily benzodiazepines, have significant limitations in the perioperative period of thoracic surgery, including respiratory depression, dizziness and residual central effects, which hinder early ambulation. As a new-generation dual orexin receptor antagonist, Lemborexant exerts its sleep-promoting and anti-stress effects by precisely blocking excessive arousal pathways. Furthermore, it causes no respiratory depression, no hangover-like effects the following day, and does not impair muscle strength or mucus clearance, offering the potential to meet the dual requirements of sleep quality and high safety in Enhanced Recovery After Surgery (ERAS) protocols for thoracic surgery. However, there remains a lack of prospective clinical evidence regarding its application in the high-stress, high-pain perioperative acute cohort of thoracoscopic surgery. This study aims to conduct a prospective, randomised, double-blind, placebo-controlled clinical trial to improve perioperative sleep quality in VATS patients. The primary outcome measure of the study was the difference in the incidence of perioperative sleep disorders (PSD) between the two groups, as assessed by the total Richards-Campbell Sleep Questionnaire (RCSQ) score on the night of surgery. The study aims to investigate the causal relationship between short-term perioperative Lemborexant intervention and improvements in patient sleep and postoperative recovery quality. The anticipated results will provide clinical evidence of the safety and efficacy of Lemborexant for use in high-stress populations during the perioperative period.

Outcome Measures

Primary Outcomes (1)

  • The incidence of postoperative sleep disturbance (PSD)

    Differences in the incidence of perioperative sleep disorders (PSD) between the two groups, as assessed by the total score on the Richards-Campbell Sleep Questionnaire (RCSQ). The scale comprises five core items evaluating distinct sleep domains: sleep depth, sleep latency, frequency of awakenings, ability to return to sleep, and overall sleep quality. Each item is rated on a 100-mm visual analogue scale (VAS). The total score is calculated as the mean of the five core item scores, yielding a range from 0 to 100. A higher total score indicates better perceived sleep quality. Specifically, a score of 0 represents the worst possible sleep, while a score of 100 represents the best possible sleep.

    The first night after the operation

Secondary Outcomes (3)

  • Objective sleep quality

    From the night before surgery to the second night after surgery (three consecutive nights).

  • Postoperative pain scores

    At 24 and 48 hours postoperation

  • Postoperative anxiety and depression

    The day before the operation and on the third day after the operation, or upon discharge
