Sustainable Anaesthesia Practices in EUROPE - a Prospective International Cohort Study

Brief Summary

In response to the climate crises, Societies of Anaesthesiology around the globe call for action to reduce the carbon footprint of daily clinical work. They recommend the use of regional and total intravenous anaesthesia, and for inhalational anaesthesia cases, the use of sevoflurane with low fresh gas flow (FGF \< 0.5 lpm) settings. Surprisingly, the type of anaesthesia and ventilation settings commonly used remain largely unknown. This pragmatic observational cross-sectional assessment at all anaesthesia workstations in participating European hospitals in daily routine aims to evaluate anaesthesia practices in the paediatric and adult patient population.

Conditions

Anaesthesia Conduction; Paediatric and Adult Patients; Carbon Footprint in Anesthetic

Outcome Measures

Primary Outcomes (1)

• Type of anaesthesia (inhalational and intravenous general anaesthesia, regional anaesthesia, sedation, combinations, monitoring only)

  The type of anaesthesia (inhalational and intravenous general anaesthesia, regional anaesthesia, sedation, combinations, or monitoring only) will be recorded by a trained team member collecting data perioperatively 5-60 minutes after skin incision or start of procedure, respectively. In the event that the anaesthetic approach changes intraoperatively, only the technique recorded at that time point will be used for analysis. Any local anaesthetic infiltration performed by the anaesthetist will be classified as regional anaesthesia, whereas if the surgeon alone administers local anaesthetic, this will not be classified by regional anaesthesia.

Study Population

SUSTAIN-EUROPE is designed to close the knowledge gap on contemporary anaesthesia practices in both adult and paediatric populations

You may qualify if:

• All patients receiving any form of anaesthesia care-whether general or regional anaesthesia, monitored sedation, or monitoring only-from an anaesthetist at an anaesthesia workstation in participating European hospitals during the selected data-collection recruitment period

You may not qualify if:

• Patients (or legal guardians) who decline consent and patients for whom valid informed consent cannot be obtained due to language barriers or other factors preventing adequate information and understanding.
