Comparison Between Low-volume Versus Standard-volume Ultrasound-guided Bilateral Intermediate Cervical Plexus Block for Patients Undergoing Thyroidectomy: A Randomized Controlled Trial.
Thyroidectomy is commonly associated with mild-to-moderate postoperative pain that may affect respiratory function and recovery. Bilateral intermediate cervical plexus block provides effective analgesia, but larger local anesthetic volumes may increase phrenic nerve spread and diaphragmatic dysfunction. Low-volume ultrasound-guided block may provide adequate analgesia while better preserving diaphragmatic function and postoperative respiratory performance

• Patients scheduled for elective thyroidectomy under general anesthesia.
• American Society of Anesthesiologists (ASA) physical status I-II.
