Eye Mask: A light-blocking eye mask will be used during nighttime sleep to reduce exposure to ambient light and support sleep.
Study summary
Coronary artery bypass graft (CABG) surgery is an effective treatment for coronary artery disease; however, sleep disturbances and delirium are common during the postoperative period and may adversely affect recovery. Environmental factors, particularly light exposure, can disrupt the sleep-wake cycle and contribute to poor sleep quality. Eye masks offer a simple, safe, and non-pharmacological method of reducing light exposure and supporting sleep. This study aims to determine the effect of eye mask use on sleep quality and delirium levels in patients following CABG surgery.

Primary outcome measure(s)
Postoperative Sleep Quality Assessed Using the Richards-Campbell Sleep Questionnaire — Postoperative day 5, postoperative day 7, and the day of hospital discharge(postoperative day 8-10) Postoperative sleep quality will be assessed using the Richards-Campbell Sleep Questionnaire. The total score ranges from 0 to 100, with higher scores indicating better sleep quality.
Postoperative Delirium Assessed Using the Nursing Delirium Screening Scale — Postoperative day 5, postoperative day 7, and the day of hospital discharge (postoperative day 8-10) Postoperative delirium will be assessed using the Nursing Delirium Screening Scale (Nu-DESC). The scale consists of five items, each scored from 0 to 2, yielding a total score ranging from 0 to 10. Higher scores indicate greater delirium severity, and a total score of 2 or higher indicates the presence of delirium.Postoperative day 5, postoperative day 7, and the day of hospital discharge (postoperative day 8-10)
