THE NEUROPATHIES COMPLICATING PERIPHERAL NERVE BLOCKS: TWO CASES STUDIES

Peripheral nerve blocks have become a gold standard for anesthesia and postoperative analgesia in limb and girdle surgeries due to the feeling of security, the simplicity of locoregional anesthesia, the absence of certain adverse effects when general anesthesia and especially in the quality of postoperative analgesia. However, locoregional anesthesia has a certain risk.We present two case reports of peripheral neuropathy after locoregional anesthesia involving the lumbar plexus and median nerve.We discuss through literature review, pathophysiology mechanisms, risk factors, management and prognosis of nerve injury during locoregional anesthesia.
