Abstract

Femoral nerve block with tumescent anesthesia is used to perform the radiofrequency ablation of varicose veins. The surgery can be done as day-case. But if recovery from motor block is delayed, it can make hospital discharge difficult. Prolonged femoral nerve blocks with motor blockade of the quadriceps have been noted after the use of bupivacaine. The motor blockade lasted up to 30-40 hours when 15-30 mL of 0.5% bupivacaine was used. However, it was rarely reported in ropivacaine. We report that femoral nerve block with 15 mL of 0.375% ropivacaine induced prolonged motor blockade up to 30 hours.
