상세 설명
Postoperative pain following vagus nerve stimulation (VNS) implantation surgery originates from both cervical and infraclavicular surgical incisions. Although opioid analgesics are commonly used for postoperative pain control, minimizing opioid exposure is particularly desirable in patients with drug-resistant epilepsy because opioid-related adverse effects may delay recovery and potentially influence neurological assessment.
The intermediate cervical plexus block (ICB) is an ultrasound-guided regional anesthesia technique that provides sensory blockade of the superficial branches of the cervical plexus while allowing accurate deposition of local anesthetic between the investing and prevertebral layers of the deep cervical fascia. Previous studies have demonstrated the effectiveness of cervical plexus blocks in various cervical surgical procedures; however, evidence regarding their use during VNS implantation surgery remains limited.
This prospective, randomized, double-blind, placebo-controlled study compares ultrasound-guided ICB using 10 mL of 0.25% bupivacaine with a placebo injection of 10 mL normal saline administered after induction of general anesthesia. The primary objective is to determine whether ICB reduces postoperative opioid requirements during the first 24 hours after surgery. Secondary objectives include evaluation of intraoperative remifentanil consumption, postoperative pain scores, time to first rescue analgesic, length of hospital stay, and postoperative seizure incidence. The findings are expected to provide evidence regarding the effectiveness and safety of ultrasound-guided intermediate cervical plexus block as part of multimodal analgesia for patients undergoing VNS implantation surgery.
