Femoral Nerve Block

This procedure can use local anesthetics, combined with corticosteroids or saline/hyaluronic acid for hydrodissection if necessary. The femoral nerve and surrounding structures are usually located under ultrasound guidance, and a fine needle is slowly injected percutaneously to form a separation zone around the nerve, reducing adhesion and irritation. Sensory and motor responses and vital signs are monitored during the procedure. Short-term observation after the operation focuses on changes in numbness, muscle strength, and pain, with the goal of relieving pain and improving function. The above is general health information, not medical advice; the specific plan is subject to specialist evaluation and hospital protocols.
