Summary
This pilot study investigates whether melatonin can improve sleep quality in critically ill patients admitted to the ICU. Participants will wear a headband device to measure their sleep patterns and then receive a dose of melatonin. The study lasts two days and aims to see if melatonin can help these patients get more restful sleep.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Melatonin
- What this could lead to
- If it works, this could point toward a simple, safe way to improve sleep for critically ill patients in the ICU.
- What could go wrong
- This is a very small pilot study with only 30 participants, so results may not be conclusive or apply to all ICU patients. Melatonin may not significantly improve sleep in this setting.
