Summary

This trial is testing whether the sleep drug suvorexant can help decrease wakefulness after surgery in elderly patients in the ICU.

Who is the study for?
This trial is for adults over 60 who are recovering from coronary artery bypass graft surgery in the ICU. They must speak English and not have severe obesity, known pregnancy, significant heart or kidney failure, liver failure, coma, delirium at enrollment time, certain cognitive impairments or psychiatric conditions.
What is being tested?
The study tests if suvorexant can improve sleep after surgery by reducing wakefulness during the night. Participants will receive either suvorexant or a placebo for seven nights post-extubation. Sleep quality will be monitored using EEG technology to measure various sleep parameters.
What are the potential side effects?
Suvorexant may cause side effects such as daytime drowsiness, dizziness upon standing (which could lead to falls), altered mental state or mood changes like depression and suicidal thoughts in rare cases.
