[Metabolic investigations under electro-stimulation and neurolept anaesthesia (author's transl)]

During ophthalmic operations the effects of electrostimulation anaesthesia on metabolites, as glucose, glycerol, ketone bodies, and on blood gas and acid base parameters, were investigated in 10 patients with normal circulation and metabolism. They were compared with those of a group operated under neuroleptanesthesia. Both groups of patients were treated with muscle relaxation and controlled normoventilation by a N2O/O2 (1:1) mixture. As the determined parameters gave no evidence of significant differences between the two groups, it is concluded that electrostimulation anaesthesia and neuroleptanaesthesia produce comparable analgesia.
