What this trial studies

This clinical trial aims to evaluate the impact of melatonin on the sleep patterns of resident trainees working night float shifts in various medical specialties. Participants will be randomized to receive either melatonin or a placebo, with their sleep monitored using portable EEG devices over a 12-day period. The study will assess changes in sleep quality and quantity, particularly focusing on deep sleep and REM sleep, to determine if melatonin can effectively improve sleep during demanding night shifts.

Who should consider this trial

Good fit: Ideal candidates include residents in their first to fifth year of training in anesthesiology, general surgery, obstetrics and gynecology, general medicine, or pediatrics at the University of Virginia.

Not a fit: Patients currently using sleep aids, diagnosed with sleep disorders, or having certain medical conditions such as high blood pressure or depression may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a non-invasive method to enhance sleep quality for medical residents, potentially improving their overall performance and well-being.

How similar studies have performed: Previous studies have shown that melatonin can effectively realign circadian rhythms and improve sleep quality in shift workers, suggesting potential success for this approach.
