Background: Bilateral superficial cervical plexus block (BSC PB) is widely used for managing pain after surgery, but the ideal dosage of anesthetic agents has to be determined to manage the severity of post-thyroid surgical pain. Method: 60 (sixty) patients were selected for BSCPB with a saline group P (n= 20 patients), Ropivacaine 0.487% Group R (n= 20 patients). Ropivacaine 0.487% plus Clonidine 50μg group RC (n= 20 patients). Sufentanil was given during the intraoperative period for a 20% increase in arterial mean pressure or heart rate in patients with a bispectral index between 40 and 60. All patients received 4 gm of acetaminophen during the first 24 hours after surgery. The pain score was checked every 4th hourly, and Nefopam was given to reduce pain with scores >4 on a numeric pain scale. Results: The comparison of the mean values of demographic characteristics, age, height, and duration of surgery (minutes) remains insignificant (p>0.001) thus indicating all groups have similar parameters. The SBP at the end of resection, extubation was statistically significant in group RC (p<0.001). The operative requirement of sufentanil and pain score in PACU were statistically significant in Group RC compared to other groups (p<0.001). Conclusion: In the comparative analysis, it is concluded that group RC (Ropivacaine +Clonidine) was effective in the management of pain reduction and safer to maintain hemodynamic status.
