Clinical Trial Network

Call for centres is open: join the Clinical Trial Network (CTN)!

The ESA Research Committee has selected the following multi-centre studies to enter the ESA Clinical Trial Network (CTN). Your hospital may join one of the study listed below as a centre. The first step in this process is to apply to participate in one of the studies and become an ESA CTN active centre.

  • MET-REPAIR:MET: REevaluation for Perioperative cArdIac Risk (MET-REPAIR) a European, Prospective, observational, multi–centre cohort study". Chief Investigator: Dr. Giovanna LURATI BUSE (University Hospital Düsseldorf, Düsseldorf, Germany)
  • SQUEEZE Study: Vasopressor therapy following surgery. A prospective international observational multicentre study (Ib Jammer, Norway)
  • ARCTIC-I Study: Anaesthesiological Routine Care for Thrombectomy in Cerebral Ischaemia. A prospective, observational, European, multicentre study (Andreas Ranft, Germany)


  • The ESA CTN is open to all clinicians meeting study protocol criteria.
  • Individuals and Institutions/Centres may participate in several studies of the ESA CTN at the same time.
  • Centres throughout Europe are invited to participate in ESA CTN studies. Some studies are also open to non-European sites (study protocol specific).
  • In case several individuals from the same department apply to participate in the same study, only one person for each centre will be appointed as responsible for the centre and will be referred to as ‘Principal Investigator.’
  • If several departments from the same institution apply to participate in a CTN study and if these departments have buildings at different locations, it may be possible to consider the 2 locations as 2 separate study sites.


You are invited to submit contact details on behalf of your hospital in order to become an ESA CTN centre participating in one or more studies.

  • Completion of the Online Call for Centres Form will facilitate coordination and is mandatory for registering the Institution’s participation in an ESA CTN study.
  • MET-REPAIR registration is only possible for centres in the UK.
  • All fields on the ‘Call for Centres form’ marked with an asterisk are mandatory. More information can be found here, for advantages resulting from the various membership types, please refer to the ESA membership section.
  • The ESA Secretariat will acknowledge receipt of the ‘Call for Centres form’ and will contact centres providing them with additional study information.
