Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The patient is placed in a supine position with the head turned away from the side to be blocked, and then the sternocleidomastoid muscle (SCM) is identified by slight head elevation. SCPB is performed with a 26-gauge needle that is inserted at the midpoint of the posterior border of the SCM muscle and the needle is advanced just past the SCM muscle.

nerve block
After general anaesthesia,the patient is placed in a supine position with the head turn away from the side to be blocked, and then the sternocleidomastoid muscle (SCM) is identified by slight head elevation. SCPB(superficial cervical plexus block) is performed with a 26-gauge needle that is inserted at the midpoint of the posterior border of the SCM muscle and the needle is advanced just past the SCM muscle. The mixture is prepared with 20ml of 0.5% ropivacaine in Group 1
