[Peripheral nerve block as a component of anesthesia during operations on lower extremity vessels].

Lumbar plexus block via inguinal paravascular access that was included as part of an anesthetic support at venectomy in the great saphenous vein, was studied for its impact on the development of postoperative pain syndrome and stress responses. The authors revealed a significant postoperative pain relief at rest and in motion, and reductions in the need for analgesics and in the magnitude of a stress response to a surgical injury.
