Summary

This trial tests whether wearing a light-blocking eye mask at night can improve sleep quality and reduce delirium in patients recovering from coronary artery bypass graft (CABG) surgery. About 100 adults scheduled for elective CABG will wear the mask during nighttime sleep, and their sleep quality and delirium levels will be measured in the days after surgery. The goal is to see if this simple, non-drug approach can support recovery by reducing light exposure that disrupts the sleep-wake cycle.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
A light-blocking eye mask worn during nighttime sleep
What this could lead to
If effective, this simple, drug-free approach could become a standard part of post-surgical care to improve sleep and reduce delirium in heart surgery patients.
What could go wrong
The trial is relatively small and early, and results may not apply to all patients. The eye mask may be uncomfortable for some, and its effect on delirium is uncertain.
