What this trial studies

This study evaluates the impact of melatonin on sleep quality, anxiety levels, and opioid requirements in adults undergoing coronary artery bypass graft (CABG) surgery. It addresses the common issue of sleep disturbances that patients experience post-surgery, which can significantly affect their recovery and quality of life. The study involves administering either melatonin or a placebo to participants and monitoring their outcomes during the postoperative period. The research aims to determine if melatonin can improve sleep and reduce anxiety in this patient population.

Who should consider this trial

Good fit: Ideal candidates are adults aged 40-60 who are scheduled for standard on-pump CABG surgery.

Not a fit: Patients with a history of sleep disorders, severe respiratory or circulatory diseases, or those taking certain psychiatric medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved sleep quality and reduced anxiety for patients recovering from CABG surgery.

How similar studies have performed: While the use of melatonin for sleep issues is well-documented, this specific application in CABG patients is relatively novel and has not been extensively tested.
