Sustainable Anaesthesia Practices in EUROPE - a Prospective International Cohort Study
An observational study of Anaesthesia Conduction and Paediatric and Adult Patients, run by European Society of Anaesthesiology.
Trial 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… Read more about this study

About this study
Official title: Sustainable Anaesthesia Practices in EUROPE
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: 5-60 min after the skin incision

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.

Questions about this trial
What is this clinical trial studying?
An observational study of Anaesthesia Conduction and Paediatric and Adult Patients, run by European Society of Anaesthesiology.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 28 Nov 2025. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Type of anaesthesia (inhalational and intravenous general anaesthesia, regional anaesthesia, sedation, combinations, monitoring only) (time frame: 5-60 min after the skin incision). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Nov 2025.
