Effect of Virtual Reality and Binaural Beat on Sleep and Comfort in Adults After Mechanical Valve Replacement Surgery

This randomized clinical trial will evaluate the effects of four interventions on sleep disturbances and patient discomfort in adult patients after prosthetic mechanical valve replacement. Sleep disturbances are common due to the sound of the mechanical valve. Participants will be randomly assigned to one of four groups: (1) VR Group (2) Binaural Beat Group listening to binaural beats for 20 minutes (3) VR + Binaural Beat Group combining both interventions, and (4) Control Group receiving standard postoperative care without interventions. Primary outcomes include sleep quality and patient-reported discomfort measured during the early postoperative period. The study aims to identify which intervention or combination is most effective in improving recovery and patient comfort.

Inclusion criteria

• Patients will be eligible for participation following mechanical valve replacement surgery if they are willing to participate, able to provide informed consent, and meet the following criteria: male or female aged 18 years or older, hemodynamically stable, oriented and conscious without cognitive impairment, free from visual or auditory impairments, able to communicate orally in Arabic, not receiving analgesics or sedatives within at least four hours prior to the intervention, and having no history of epilepsy, seizure disorders, or recurrent migraines.

Exclusion criteria

• The study's exclusion criteria will include participants with facial or head injuries, a history of vertigo or severe motion sickness, immediate postoperative cardiac arrest, the use of hypnotic medications, the presence of a tracheostomy, or any implanted body hardware.
