The intervention is performed simultaneously with the use of eye masks and earplugs in the cardiac intensive care unit for three consecutive nights (from the second night of admission) from 21-22 to 6-7 am by the caring nurse for the experimental group. Press and twist the earplugs into a spiral and thin, and then by pulling the top of the ear up and back, smooth the ear canal and press the sponge into the ear canal and hold 20-30 until the sponge expands in the ear canal. And after 10 minutes, check if the eye masks and earplugs are in place. If necessary, the patient's eye masks and earplug can be removed and reused to communicate with the patient and perform medical and nursing care. The earplugs is disposable, but the eye masks can be used for three nights of intervention, Randomization description: Patients will be recruited using convenience sampling method and then will be randomly assigned to the experimental (group A) and control (group B) groups using block method (19 blocks) of length 6. The blocks will be numbered and sealed in 19 sequentially numbered opaque envelopes in random order (by someone outside the research team and unaware of the research objectives). The envelopes will be opened individually and the patients will be assigned to the relevant groups. The Random Allocation Software 2.0 will be used to generate randomization sequences, Blinding description: the Assessor and Statistician will be blind to Randomization. N/A delirium and sleep quality. Intervention 1: The intervention is performed by using eye masks and earplugs from the second night after coronary artery bypass graft surgery for three consecutive nights (from the second night of admission) from 21-22 to 6-7 in the morning by the Caring nurse for the experimental group. paksaman eye masks (Model 504, made in Iran) made of a thin layer of foam covered by a layer of anti-allergy fabric and placed with a soft and light elastic around the head And the classic 3M sponge earplug with 33 dB sound reduction capability will be used.Press the earplug into a spiral and thin, and then by pulling the top of the ear up and back, smooth the ear canal and press the sponge into the ear canal and hold 20-30 until the sponge expands in the ear canal. And after 10 minutes, check if the blindfold eareplug and earmuffs are in place.If necessary, the patient's eye masks and earplug can be removed and reused to communicate with the patient and perform medical and nursing care. The eye mask is disposable, but the blindfold can be used for three nights of intervention. Intervention 2: The control group also receives only routine ward care without any intervention.
