Scientific titleEfficiency and safety of inhalative long-term sedation with sevoflurane/remifentanil compared to intravenous sedation with propofol/remifentanil in intensive care patients: a prospective randomised clinical trial
Study acronymAnaconda trial
Study objectivesSedation with inhalative sedation using sevoflurane/remifentanil is more effective compared to intravenous sedation using propofol/remifentanil.

Please note that as of 06/02/09 this record was updated to include information on the ethics approval and the anticipated start date. The initial anticipated start date was 01/09/2008.
Ethics approval(s)Added 06/02/2009: Ethics Board of the University Halle/Saale (Germany) gave approval in November 2008.
Health condition(s) or problem(s) studiedSedation
InterventionSedation using the AnaConDa® system.

The study protocol implies a randomised prospective study with two groups including 50 patients in each group. Group S will be sedated with sevoflurane and remifentanil and Group P with propofol (disoprivan 2%) and remifentanil for day one to four. From the fifth day only the intravenous propofol is going to be switched to midazolam to avoid the danger of a propfol infusion syndrome. A rescue medication like esketamin or clonidin are allowed when indicated for example for shivering or insufficient sedation depth. There is also the possibility to exchange the remifentanil to sufentanil in both groups if the clinical situation demands it for example because of a persistent bradycardia during the analgosedation.
Intervention typeDrug
PhaseNot Applicable
Drug / device / biological / vaccine name(s)Sevoflurane, remifentanil, propofol
Primary outcome measure(s)

Weaning time (time end of sedation until spontaneous breathing)
