Study Design

Allocation randomized
Intervention model parallel assignment
Primary purpose treatment
Masking participant, investigator, outcomes assessor
(Active Comparator)
Physostigmine administered intravenously at a dose of 24 mg + 25 min a 0,04 mg/kg milligram(s)/kilogram
physostigmine Anticholium
(Placebo Comparator)
solution administered intravenously 24 mg + 25 min a 0,04 mg/kg milligram(s)/kilogram
sodium chloride solution NaCl solution as Placebo comparator

time frame: baseline to 48 hours after administration

Secondary Outcomes

reduction of weaning time at mechanical ventilator of patients with symptoms of delirium
time frame: baseline to 48 hours after administration
change in the spontaneous EEG and auditory evoked potentials
time frame: baseline to 48 hours after administration
impact of the variability of heart rate
time frame: baseline to 48 hours
change in development of muscular force
time frame: baseline up to 48 hours
Occurence of Adverse events
time frame: baseline to 4 weeks after treatment
