Study: NCT04814628

Intervention type: PROCEDURE
Group type: EXPERIMENTAL
Intervention: scenario 1 : pre-oxygenation with a face mask held by the anaesthetist
Description: the face mask is held by the anaesthetist (reference technique) to obtain effective pre-oxygenation for Oxygen Reserve Index (ORI) which has reached a plateau value for more than 10 seconds. All the usual supplies and medicines are available and in the same place as usual.~The sequence is as follows:~1. Patient lying on the operating table, start of the stopwatch~2. Opening of the computerized anaesthesia file~3. Monitoring (ECG, non-invasive blood pressure, SaO2) of the patient~4. Preparation of the hypnotic (propofol or thiopental, as desired)~5. Preparation of curare (succinylcholine or rocuronium, as desired)~6. Pre-oxygenation of the patient with the face mask held by the participating anaesthetist~7. Waiting for an ORI which has reached a plateau value for more than 10 seconds~8. Conditions for general anaesthesia met for the participating anaesthetist~9. End of simulation, stopwatch stop

Group type: EXPERIMENTAL
Intervention: scenario 2: one anaesthetist in charge, face mask held by the patient for pre-oxygenation
Description: one anaesthetist is in charge of the simulated patient (volunteer), face mask held by the volunteer for pre-oxygenation for ORI which has reached a plateau value for more than 10 seconds All the usual supplies and medicines are available and in the same place as usual.~The sequence is as follows:~1. Patient entering the operating room, patient lying on the operating table, start of the stopwatch~2. Opening of the computerized anaesthesia file~3. Monitoring (ECG, non-invasive blood pressure, SaO2) of the patient~4. Preparation of the hypnotic (propofol or thiopental, as desired)~5. Preparation of curare (succinylcholine or rocuronium, as desired)~6. Face mask held by the patient for pre-oxygenation~7. Waiting for an ORI which has reached a plateau value for more than 10 seconds~8. Conditions for general anaesthesia met for the participating anaesthetist~9. End of simulation, stopwatch stop

Group type: EXPERIMENTAL
Intervention: scenario 3: one anaesthetist in charge, THRIVE used for pre-oxygenation
Description: All the usual supplies and medicines are available and in the same place as usual.~The sequence is as follows:~1. Patient entering the operating room, patient lying on the operating table, start of the stopwatch~2. Opening of the computerized anaesthesia file~3. Monitoring (ECG, non-invasive blood pressure, SaO2) of the patient~4. Preparation of the hypnotic (propofol or thiopental, as desired)~5. Preparation of curare (succinylcholine or rocuronium, as desired)~6. THRIVE for pre-oxygenation~7. Waiting for an ORI which has reached a plateau value for more than 10 seconds~8. Conditions for general anaesthesia met for the participating anaesthetist~9. End of simulation, stopwatch stop

Intervention type: PROCEDURE
Group type: EXPERIMENTAL
Intervention: scenario 4: one anaesthetist and one nurse anaesthetist in charge, the face mask is held by the anaesthetist or the nurse anaesthetist
Description: All the usual supplies and medicines are available and in the same place as usual.~The sequence is as follows:~1. Patient entering the operating room, patient lying on the operating table, start of the stopwatch~2. Opening of the computerized anaesthesia file~3. Monitoring (ECG, non-invasive blood pressure, SaO2) of the patient~4. Preparation of the hypnotic (propofol or thiopental, as desired)~5. Preparation of curare (succinylcholine or rocuronium, as desired)~6. Pre-oxygenation of the patient with the face mask held by the participating anaesthetist or nurse anaesthetist~7. Waiting for an ORI which has reached a plateau value for more than 10 seconds~8. Conditions for general anaesthesia met for the participating anaesthetist~9. End of simulation, stopwatch stop
