Effect of the Addition of Ketamine to Sevoflurane Anesthesia in Electroconvulsive Therapy

Parallel-group randomised trial comparing sevoflurane induction plus a single IV bolus of ketamine 0.5 mg/kg versus sevoflurane plus saline during ECT; groups described as Group SK and Group SS.

Primary measurements include motor and EEG seizure durations and haemodynamic responses (MAP and HR) recorded at baseline, post-induction, and at 0, 1, 3 and 10 minutes after seizure end.
