An ultrasound probe was placed at the midline of inguinal crease and moved medially and caudally to visualize the fascial space between the adductor longus (or pectineus) and adductor brevis muscles. We injected 20mL 1% lidocaine containing epinephrine into the interfascial space using a transverse plane approach to make an interfascial injection, not an intramuscular swelling pattern. And just distally, firm pressure was applied for 3min. Afterwards, surgery was performed under spinal anesthesia. The time required for identification and location of the nerve was 20±15 and 30±15s, respectively. Adductor muscle strength, which was measured with a sphygmomanometer, decreased in all patients, from 122±26mmHg before blockade to 63±11mmHg 5min after blockade. No movement or palpable muscle twitching occurred in 23 cases, slight movement of the thigh not interfering with the surgical procedure was observed in 1 case, thus the obturator reflex was successfully inhibited in 96% of cases. Ultrasound-guided single interfascial injection is an easy and successful technique for obturator nerve block.
