Interventions

Drug : Ultrasound-guided intermediate cervical plexus is performed with 0.5&#37

ropivacaine accoding to group assignment. The difference in both group is volume of ropivacaine 0.5&#37

used. After sterile skin preparation and skin infiltration with 2 mL of 2&#37

lidocaine, a needle was advanced in-plane into the intermuscular plane between the sternocleidomastoid and scalene muscles. Then, local anesthetic was injected.
