[Loss of resistance in axillary plexus blockade].
The results of the "loss of resistance" method for identification of the perivascular space are demonstrated. The axillary plexus with its accompanying structures is embeded in the perivascular space. 20 pressure readings were performed with a special transducer. A statistically significant pressure loss was demonstrated after passing the vascular and nerve sheath. The distinct pressure differences during the tissue penetration are recognized with the finger guiding the syringe, similar to the technique used for peridural anaesthesia. We thus believe that we can offer an exact method for blocking the axillary plexus with maximum safety which does not rely on the cooperation of the patient.
