[Experimental definition of an optimal arrangement of electrodes for localisation of nerves (author's transl)].
The use of electrical stimulation for the localisation of nerves facilitates regional anaesthesia, especially by assuring a sufficient approach of the tip of the cannula to the nerve by the intensity and duration of an impulse necessary for its stimulation. This necessitates an adequate and constant distribution of the intensity of the stimulus in the surroundings of the tip of the cannula and the capability to define the current of the impulse. In the electrolytic tank the distribution of the stimulating intensity was studied in 4 different types of electrode arrangements. An electrode arrangement most suitable for nerve blockades was found. It may be produced by coating an injection cannula with 1 conducting and 2 isolating layers.
