Does Bilateral Superficial Cervical Plexus Block Decrease Analgesic Requirement After Thyroid Surgery?

Abstract Objective:Uses of simple analgesics were found insufficient to manage pain after thyroid surgery. We hypothesized that using bilateral superficial cervical plexus block (BSCPB) might influence the pattern of immediate postoperative pain and analgesic consumption. Results: A total of 74 willing patients involved. Half of them had received BSCPB with 10 ml of 0.25% bupivacaine just before induction and the remaining half did not. Postoperatively, patients were assessed at immediate, 2nd, 6th, 12th and 24th hours. At all endpoints, NRS-11 scores for pain were significantly lower in the block group. Time to first analgesic requirement was significantly longer 132.31 ± 71.46 vs 71.4 ± 59.99, p = 0.009. Opioid and total analgesic consumption were reduced by BSCPB in the first 24 postoperative hours. There was low but non-significant rate of PONV in the block group. No clinically important adverse event was noted related to BSCPB.

Time to first analgesic requirement was significantly longer 132.3 ± 71.5 min vs 71.4 ± 60.0 min, p = 0.009. Opioid and total analgesic consumption were reduced by BSCPB in the first 24 postoperative hours. There was low but non-significant rate of PONV in the block group.

Background: When general anaesthesia is employed for a surgery, the hemodynamic changes are intense during intubation, intraoperative stress and extubation. Hence, in the present study, by employing Bilateral Superficial Cervical Plexus Block using 0.5% Bupivacaine prior to skin incision, assessment of hemodynamic effects during intraoperative period is done. The aim of the study was to compare the intra operative hemodynamic status and the safety of bilateral superficial cervical plexus block with general anesthesia in thyroid surgerie.Methods: Bilateral superficial cervical plexus block was performed in patients undergoing simple thyroid surgery using normal saline in 29 control group patients and 0.5% Bupivacaine in 29 study group patients. Intraoperative hemodynamic status was monitored in both the groups using parameters such as heart rate, systolic blood pressure, diastolic blood pressure and mean blood pressure.Results: Hemodynamic parameters are not altered during the intraoperative period in the study and control group.Conclusions: Bilateral Superficial Cervical Plexus Block with bupivacaine did not alter the intraoperative hemodynamic parameters.
