Summary
This study looked at whether giving a drug called guanfacine through an IV can help reduce delirium and improve thinking in very sick patients in the intensive care unit (ICU).

Researchers measured how many days patients were free of delirium or coma, and how well their brains worked after leaving the hospital.
