%X Recent literature has established the role of stellate ganglion block (SGB) for management of acute postoperative pain. The effects of dexmedetomidine as an adjuvant to lignocaine in a preoperative SGB for postoperative pain relief have not been evaluated so far. The following randomised, double-blinded, control trail included 54 patients scheduled for upper limb orthopaedic surgery under general anaesthesia. Preoperative ultrasound-guided (USG) SGB was performed in all patients. Group I (n£¿=£¿18) received 3.5£¿mL of a solution (3£¿mL 2% lignocaine£¿+£¿0.5£¿¦Ìg/kg dexmedetomidine for SGB) and 15£¿mL of intravenous (IV) normal saline (NS). Group II (n£¿=£¿18) received 3.5£¿mL of a solution (3£¿mL 2% lignocaine£¿+£¿0.5£¿mL NS for SGB) and 15£¿mL of IV NS. Group III (n£¿=£¿18) received 3.5£¿mL of a solution (3£¿mL 2% lignocaine£¿+£¿0.5£¿mL of NS for SGB) and 0.5£¿¦Ìg/kg dexmedetomidine in 15£¿mL of IV NS. Postoperatively tramadol consumption and Visual Analogue Scale (VAS) score were recorded up to 48£¿hours. The cumulative tramadol consumption at the end of 48£¿hours (p£¿=£¿0.01) was significantly reduced in the group I as compared to group II. In group I, postoperative VAS at rest was significantly reduced up to 12£¿hours postoperatively as compared to group II (p£¿=£¿0.05). The cumulative tramadol consumption was not reduced significantly in group III compared to group II (p£¿=£¿0.51). Dexmedetomidine as an adjuvant to SGB along with lignocaine produced a significant tramadol sparing effect and superior analgesia as compared to IV dexmedetomidine and control group.
