ABSTRACT
In this study we evaluated the analgesic efficacy of bilateral superficial cervical plexus block after thyroid surgery. Sixty patients were assigned to two groups. General anesthesia was induced with 2mg/kg propofol, 0.1mg/kg vecuronium and 1.5µg fentanyl IV for both group. After endotracheal intubation, bilateral superficial cervical plexus block with 0.25% bupivacaine 15ml in each side was performed in Group I. In Group II (control) no regional block was administered. Intravenous on demand analgesic was used to evaluate postoperative analgesic requirement. Neither visual analog scale scores nor intravenous analgesics doses were different between the groups. The first analgesic requirement time in Group I was significantly longer than for the control group. The incidence of nausea and vomiting was significantly lower in Group I than Group II. We concluded that bilateral superficial cervical plexus block with 0.25% bupivacaine did not decrease analgesic requirement after thyroid surgery.
