[Effects of ketamine on somatosensory evoked potentials during nitrous oxide anesthesia in humans].

Abstract

The effects of ketamine with 60% nitrous oxide were studied on subcortical sensory evoked potentials recorded at Erb's point (N9), neck (N13) and on cortical potentials recorded at the scalp (N20) following median nerve stimulations in 7 neurologically normal patients. Latencies and amplitudes of the potentials were measured and compared with postinduction… (More)
