Exogenous Melatonin in Intensive Care Unit Chronodisruption

Summary

To this day, a small number of studies have evaluated the effect of melatonin on the modifications of the characteristics of sleep in critical care units, with mostly a small studied population. However, no study has been realized on a large population, nor has it evaluated the association between genetic factors and response to treatment (melatonin), hence the originality of our study. In our study we hypothesized that systematic melatonin usage in ICU can ameliorate the total sleep time and the fragmentation index and can decrease the confusion related to sleep deprivation.
