Progressive changes in the electroencephalogram produced by ketamine Progressive changes in the electroencephalogram produced by ketamine. Stages 1 to 3 are achieved with racemic ketamine and its S(+) isomer. With R(–) ketamine, stage 2 was the maximal electroencephalographic depression produced. [Redrawn from Kilpatrick GJ.
