An interventional study of Group 1 will receive 10ml of 0.25% bupivacaine and Group 2 will receive 10ml of 0.25% ropivacaine on each side. in Postoperative Pain, sponsored by Sargodha Medical College. Enrolling by invitation at 1 site in Pakistan. Open to participants aged 20 Years to 40 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-08-21.

There is significant difference between bupivacaine and ropivacaine in terms of postoperative pain assessment in patients undergoing total thyroidectomy with bilateral superficial cervical plexus block.
Exclusion Criteria:
Procedure: Group 1 will receive 10ml of 0.25% bupivacaine
Procedure: Group 2 will receive 10ml of 0.25% ropivacaine on each side.
After placing the patients in a supine position with the neck slightly extended and rotated away from the side to be blocked,the procedure will be performed under sterile aseptic conditions.The sternocleidomastoid muscle will be identified,and a high-frequency (1O MHz) linear probe will be positioned transversely over the muscle,between the mastoid and clavicle. The cutaneous nerves of the cervical plexus,visible as round hypoechoic structures in the fascial plane beneath the muscle,will be targeted using a 22-gauge short block needle (5 cm) inserted in-plane with the transducer. Negative aspiration will be performed during injection to avoid inadvertent intravascular delivery. An emergency crash cart will remain available throughout the procedure.
