Plain English Summary
Background and study aims
Delirium is a syndrome which may present either in a hyperactive form (severe confusion and disorientation) or a hypoactive form (sudden withdrawal from interaction with the outside world). A decline in cognitive function (especially in memory and executive functions) may occur from a few days to several months after surgery – this is known as delirium and postoperative cognitive dysfunction (POCD). POCD occurs quite frequently after major abdominal surgery. The aim of this study is to find out whether giving patients the drug Physostigmine (Anticholium®) reduces the incidence of delirium and POCD.
Who can participate?
Patients aged at least 18 who are undergoing a planned elective liver resection (surgery).
What does the study involve?
A day before liver surgery the participants’ cognitive functions are evaluated with the help of paper and pencil tests. Then from the beginning of liver resection participants are randomly allocated to be treated with either Physostigmine or placebo (salt solution) administered into a vein over 24 hours. Blood tests are carried out until the 7th day after surgery. While at the hospital the health condition of the participants is monitored and for the first week after surgery they are visited by the trial team members twice a day. The cognitive tests are repeated on the 7th, 90th and 365th days after surgery.
What are the possible benefits and risks of participating?
By taking part in this study participants will help to expand our knowledge about delirium and POCD and its treatment. The study drugs are routinely used as add-on medications.

2. Peri-operative application of placebo over 24 hours
The dosage will be administered intravenously 0.02 mg/kg BW as bolus and 0.01 mg/kg BW/h (for 24 hours) from the beginning of the operation for both intervention arms. The follow up will be 1 year after drug application for all arms.

Primary outcome measure
Current primary outcome measures as of 27/06/2016:
1. Diagnostic and Statistical Manual of Mental Disorders 4th edition (DSM-IV), measured pre-operatively and up to hospital discharge
2. Cambridge Neurophysiological Test Automated Battery (CANTAB), measured preoperatively, on the 7th, 90th and 365th post-operative day. For the POCD evaluation, a POCD-control group of 25 additionally recruited patients with systemic disease and 20 patients with systemic disease from another non-interventional study (EA1/296/12 Code: Cognitive Outcome after two-stage Liver-Operation)) (ClinicalTrials.gov Identifier: NCT01809782) are analyzed.
Amendment valid from 15/02/2016: The recruitment of a control group regarding the primary endpoint evaluation of POCD was amended. A control group of 45 ASA II/III- patients (20 patients additionally recruited within the Phydelio study and 20 patients from the study (Cognitive Outcome After Two-stage Liver-Operation - NCT01809782) ) is additionally collected for measuring the learning experience during the cognitive testings. The participants are matched on age, education, and gender to the study patients.
