Depth of Anaesthesia Measured by Patient State Index (PSi) Does Not Correlate With Increased Seizure Duration During Electroconvulsive Therapy
BACKGROUND: Seizure duration during electroconvulsive therapy (ECT) correlates with treatment efficacy and may be influenced by depth of anaesthesia. The Patient State Index (PSi), derived from processed EEG, offers a potential method to monitor depth of anaesthesia during ECT. This study examined the correlation between pre-ictal PSi and EEG-seizure duration.METHODS: In this prospective observati
