Abstract
SUMMARY: 1. Duration of Analgesia: BSCPB performed by three point technique before general anaesthesia resulted in significant increase in the duration of post operative analgesia and reduction in other post operative analgesic requirements. The addition of adjuvant clonidine 2mcg/kg to ropivacaine 0.5% prolongs the duration of post operative analgesia more than using ropivacaine 0.5% alone. 2. Pain Score: At admission into PACU, the median VAS score is less in BSCPB patients. The pain score was still lesser in patients who received ropivacaine with clonidine. 3. Rescue analgesia: Post operative analgesic requirements were significantly reduced in BSCPB group. 4. Total Fentanyl dosage: There was significant reduction in intra operative fentanyl dosage in BSCPB groups. 5. Haemodynamic status: There was reduction in Systolic blood pressure, Mean arterial pressure and Heart rate during intra and post operative period and it never fell down <20% of baseline value. 6. Side effects: There was significant reduction in Post operative nausea and vomiting in BSCPB groups. CONCLUSION: Bilateral Superficial cervical plexus block performed prior to general anaethesia using ropivacaine 0.5% along with adjuvant clonidine 2mcg/kg had better post operative analgesic efficacy than ropivacaine alone in patients undergoing total thyroidectomy. It also reduces the intra operative opiates requirement, post operative rescue analgesia requirement and has lower VAS score with negligible side effects. From this study, we conclude that bilateral superficial cervical plexus block is an effective and useful method to manage post operative pain in patients undergoing total thyroidectomy.
