NCT06777342

Brief Summary

This is a multicenter, randomized, controlled clinical trial aimed to determine whether preoperative sleep interventions could reduce the incidence of adverse outcomes, such as postoperative delirium, in adult patients undergoing cardiac surgery. The study will include adult patients undergoing coronary artery bypass grafting and/or valve surgery with concomitant sleep disorders, as assessed by the Pittsburgh Sleep Quality Index. All participants will be randomly assigned to placebo, placebo + cognitive behavioral therapy, and melatonin + cognitive behavioral therapy in a 1:1:1 ratio. The primary outcome is the incidence of postoperative delirium within 7 days after surgery or before discharge, and secondary outcomes include postoperative cognitive function, sleep quality, and severity and duration of delirium. The results of this study will provide suggestions for the prevention of delirium after cardiac surgery.

Interventions

The cognitive behavioral intervention provides sleep-related education 7-14 days before surgery. The educational content should include the following aspects: 1) Establish a consistent bedtime and wake-up time, recommending a sleep schedule from 22:00 to 07:00, and avoid prolonged daytime naps; 2) Optimize the sleep environment by ensuring a quiet setting, turning off lights, and refraining from using mobile phones, computers, and other electronic devices 30 minutes before bedtime; 3) Manage diet by avoiding caffeinated foods such as chocolate, tea, and cola; 4) Engage in appropriate daytime activities as permitted by the patient's condition.

Melatonin and cognitive behavioral therapy intervention groupPlacebo and cognitive behavioral therapy intervention group
Melatonin interventionDIETARY_SUPPLEMENT

Patients in the melatonin intervention group are required to take an oral melatonin of 5 mg at 30-60 minutes before sleep (administered at 21:00) nightly for 7 to 14 days before surgery. The melatonin was provided by Kangenbei Pharmaceutical Co., LTD. (Hangzhou, Zhejiang, China).

Melatonin and cognitive behavioral therapy intervention group

Patients in the placebo group need to take oral placebos of 5 mg at 30-60 minutes (administered at 21:00) before sleep, nightly, for 7 to 14 days before surgery. The placebo is provided by Guangzhou Boji Biomedical Science Park Co., LTD. (Guangzhou, Guangdong, China).
