Effect of Eye Mask Use on Sleep Quality and Delirium After CABG Surgery

Patients undergoing coronary artery bypass graft surgery may experience substantialdisruption of their normal sleep‐wake cycle during the postoperative period. Physicalsymptoms such as pain, dyspnea, and nocturia; psychological factors such as anxiety anddepression; and environmental factors such as noise and continuous light exposure maycontribute to poor sleep. Disrupted sleep may delay recovery, reduce quality of life, andincrease susceptibility to postoperative delirium.Non‐pharmacological interventions are increasingly used to promote sleep while avoidingmedication‐related adverse effects. Reducing ambient light during nighttime sleep maysupport circadian regulation and facilitate sleep initiation and maintenance. Eye masksprovide a simple, safe, inexpensive, and readily applicable method of limiting lightexposure in clinical settings.This study will evaluate whether postoperative eye mask use improves sleep quality andreduces delirium levels in patients undergoing coronary artery bypass graft surgery. Thefindings may provide evidence for incorporating eye mask use into routine postoperativenursing care following cardiac surgery.
