The purpose of this pilot-trial is the feasibility of a large randomized, placebo controlled, doubleblind clinical trial to investigate the use of methylphenidate, rivastigmine or haloperidol in hypoactive ICU-delirium. In addition we will compare duration of delirium, severity of delirium, length of ICU/hospital stay and side effects between the different interventions.
