[Continuous plexus anesthesia to improve circulation in peripheral microvascular interventions].

Five patients were demonstrated: one finger replantation, three toe-to-finger transfers and one finger-finger transfer. An axillary plexus catheter was inserted for postoperative sympathetic blockade. This brought about spasmolysis, an increase in the circulation and an increase in the acral systolic blood pressure. Simultaneously an adequate analgesic effect was achieved through the administration of local anaesthesic. The muscle relaxation assisted the immobilisation of the extremity. The improved circulation, the analgesic effect and the suppression of the muscular activity through continuous plexus anaesthesia have a beneficial influence on healing in replanted or transferred digits.
