Randomized Controlled Trial Multicenter Study
Association between delirium and cognitive change after cardiac surgery.
Previous studies provide inconsistent data on whether postoperative delirium (POD) is a risk factor for postoperative cognitive decline (POCD). We thus investigated the relationship between POD and cognitive change after cardiac surgery and assessed the relationship between preoperative cognitive domain scores and POD. ⋯ NCT00293592.
