The authors discuss in their paper treatment of amented delirious conditions as a complication after an urgent or elective surgical operation. Contrary to hitherto applied practice, where treatment is started only at the onset of the mental disorder, the authors administered treatment in selected patients immediately after surgery. The results revealed a marked decrease of amented delirious conditions in the group of patients where treatment was started immediately after surgery.
