Delirium
Conditions
Brief summary
The level of acetylcholinesterase is suspected to correlate with postoperative delirium. The investigators therefore score patients once preoperatively and twice postoperatively with the german version of the delirium-score NuDESC (Nursing Delirium Screening Scale) and compare the results with the acetylcholinesterase activity, butyrylcholinesterase activity and the serum anticholinergic activity (SAA) at corresponding time points.
