30 patients who received electroconvulsive therapy were anaesthetized with either Propofol or Methohexitone in a randomized cross-over study. Recovery times were shorter in those who received Propofol. The decrease in diastolic pressure after induction was greater with Propofol than with Methohexitone. There was a greater increase in the blood pressure after the electroconvulsive therapy in those who received Methohexitone. The duration of convulsion was similar for both agents.
