NCT03498560

Brief Summary

The investigators are performing this research study to understand the role of sleep disturbance on the incidence/severity of delirium after surgery. The investigators will study the brain using a polysomnography device (PSG), which records the brain's electrical activity during sleep.

Limitations and Caveats

The quality of many of the PSG recordings was poor and not interpretable. After patients enrolled, many withdrew at the time the PSG was to be placed. So, sleep was recorded for fewer patients. Blood was not analyzed.
