Brief 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.

Conditions

Coronary Artery Disease; Sleep Quality; Postoperative Delirium (POD)

Coronary Artery Bypass Grafting; Eye Mask; Sleep Quality; Postoperative Delirium; Cardiac Surgery; Non-Pharmacological Intervention; Postoperative Nursing Care

Outcome Measures

Primary Outcomes (2)

• Postoperative Sleep Quality Assessed Using the Richards-Campbell Sleep Questionnaire

  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 day 5, postoperative day 7, and the day of hospital discharge(postoperative day 8-10)

• Postoperative Delirium Assessed Using the Nursing Delirium Screening Scale

  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)

  Postoperative day 5, postoperative day 7, and the day of hospital discharge (postoperative day 8-10)

Study Arms (2)

Eye Mask Group

EXPERIMENTAL

Participants in this group will wear an eye mask during nighttime sleep following coronary artery bypass graft surgery in addition to routine postoperative care.

Other: Eye Mask

Control Group

NO INTERVENTION

Participants in this group will receive routine postoperative care without the use of an eye mask.

Interventions

Eye Mask OTHER

A light-blocking eye mask will be used during nighttime sleep to reduce exposure to ambient light and support sleep.
