Comparison of bilateral ultrasound-guided intermediate cervical plexus block vs local wound infiltration for postoperative analgesia in patients undergoing total thyroidectomy

Abstract

The thyroid gland surgery is a common and painful procedure demanding analgesia. Bilateral intermediate cervical plexus block (BICPB) could be beneficial for analgesia in thyroid surgery. In this study we will evaluate the analgesic efficacy and possible side effects of ultrasound guided intermediate cervical plexus block vs local wound infiltration in patients undergoing elective thyroidectomy under general anaesthesia. The aim of this study is to evaluate the analgesic efficacy and possible side effects of ultrasound guided intermediate cervical plexus block vs local wound infiltration in patients undergoing elective thyroidectomy under general anaesthesia as a primary outcome. The secondary outcome is the assessment of the safety of ICPB and the total dose of meperidine used postoperatively (rescue analgesia) for 24 h. This Prospective, randomized study was conducted in Ain Shams University Hospitals from October 2020 to February 2021. After obtaining approval from the Research Ethical Committee of Faculty of medicine, Ain Shams University, written informed consent had been taken from 40 participants of either sex with scheduled for elective thyroidectomy after full explanation of the procedure, possible side effects and complications.
