E.1.1 | Medical condition(s) being investigated |
The drug physostigmine will be investigated in patients (men and women)undergoing a liver resection. The study medication will be administered by intravenous infusion continuously (24 hours) to prevent/reduce the rate of Delirium and the incidence of the postoperative cognitive dysfunction.
