In a prior study, delirium and plasma anticholinergic drug levels were
significantly correlated in 9 of 25 surgical intensive care patients. The
present study, using cumulative anticholinergic effects of parent compounds
of these patients' medications, found that delirious patients' medication
combinations had significantly higher cumulative anticholinergic effects
than those of nondelirious patients.
