ABSTRACT:
The invention provides a catheter set for plexus anesthesia wherein the catheter can be displaced under electric stimulation and the position of the catheter can be checked also afterwards. The catheter set is provided with a puncture cannula, a capillary plugged onto said puncture cannula, and a catheter which can be inserted through said capillary and has an open patient-side end. Into the catheter, a guide wire can be inserted, being provided with an electric contact means at its end distant from the patient and having its patient-side end exposed. The position of the guide wire and the catheter end, respectively, in the fascia can be checked by electric pulses. When the catheter remains set for a longer time period, subsequent insertion of the guide wire makes it possible to monitor and, if need be, correct the position of the catheter at all times.
