Statins may reduce odds of delirium after cardiac surgery

"A new study has provided some of the first evidence that the use of cholesterol-lowering statins before cardiac surgery decreases the odds of postoperative delirium in elderly patients. Previous studies have shown that statins reduce the incidence of morbidity and mortality after cardiac and major non-cardiac surgery. Statins have also been shown to be protective in central nervous system injury. The study is published in the January 2009 issue of Anesthesiology" - ANI
