Groups2
Group 2 names the comparator: usual care.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | EEG Guided | All patients in the EEG Guided study arm will receive the anesthetic care guided by the SedLine EEG Brain Function Monitor in addition to the conventional monitors. In addition to the conventional/standard interventions of anesthetic care, an additional intervention related to this trial is the anesthetic depth management via the titration of the propofol and remifentanil infusion rates to maintain SEF and PSI in the targeted ranges based on the SedLine EEG monitoring.~Anesthetic depth management: The propofol and remifentanil infusion rates will be adjusted to maintain the spectral edge frequency (SEF) value at 10-15 and the patient state index (PSI) value at 25-50 based on the SedLine EEG Brain Function Monitoring. | 2 | 765 | OG000 |
| Group 2 | Usual Care | All patients in the usual care arm (control) will receive the anesthetic care guided by the conventional monitors only. Patients in the control arm will be monitored using the SedLine EEG Brain Function Monitor; however, the screen of this monitor will be covered by an opaque cloth and blinded to the anesthesia team. | 1 | 767 | OG001 |
