Cutaneous Anesthesia of the Lateral Femoral Cutaneous Nerve

"All 20 study participants will receive both treatment Low dose Ropivacaine and High dose Ropivacaine in form of a nerve block injection around the lateral femoral cutaneous nerve. Treatment Low dose Ropivacaine and High dose Ropivacaine will be randomized to be given in either right or left lower extremity. If the participant is randomized to receive treatment Low dose Ropivacaine in the right lower extremity, treatment High dose Ropivacaine will be given in the left lower extremity, and vice versa. Each participant will thus constitute as their own control."
