[The transcutaneous electrostimulating anaesthesia--the results of patients with retinal and vitreous surgery (author's transl)].

The clinical results of 50 patients with retinal and vitreous surgery performed in combined electrostimulating anaesthesia are reported. Premedication consisted of a barbiturate such as medomin and of atosil, ordered the evening before surgery. 1/2 hour preoperatively 1.5--2 ml thalamonal and 0.5 mg atropine were administered intramusculary. All patients were intubated and controlled respirated; stimulation starting about 5 minutes following intubation procedure. During continuous intermittent relaxation anaesthesia was maintained by a mixture of nitrous oxide/oxygen 1:1 and electrical stimulation at the dermatoms of N. trigeminus I, II and Plexus cervicalis 3 and 4. For the first time stimulation of the dermatoms during anaesthesia was done by self adhesive electrodes. So we were able to eliminate the circumstantial and not even harmless invasivity of the needle technique. The main advantages of the new method we see in a good circulatory stability and in good postoperative cooperation of the patients. Especially in old and poor risk patients the results of transcutaneous electrostimulating anaesthesia are excellent.
