Additives have been used with lignocaine for improving analgesia and reducing tourniquet pain after IVRA. Inconsistent results have been obtained with clonidine added to lignocaine bolus.Hence,effects of injecting clonidine separately towards the end of surgery was assessed for the same study parameters.

METHODS: Eighty patients undergoing below elbow surgeries were randomly allotted to two groups to receive IVRA; group A received 40 ml lignocaine 0.5% at the beginning of procedure with normal saline 15 ml at end; group B received same amount of lignocaine and clonidine 150 μg made upto 15 ml with normal saline at end.Duration and quality of postoperative analgesia and tourniquet pain,haemodynamic parameters and adverse effects if any were noted.Data was analyzed by using EPI INFO V-07 and the results compared using Fisher’s exact test.

RESULTS: Almost all the patients in the group A required analgesic as compared to group B where less than 50% of patients needed analgesic by 15 mins.Duration of analgesia extended only upto a further 5 mins period in the group B. There was a small & statistically insignificant difference in VRS scores at 11-15 min & 16-20 mins between thegroups.All the patients expressed feeling of discomfort after tourniquet release. There was no difference with respect to haemodynamic parameters,O2 saturation or other effects during the study period between the groups.

CONCLUSION:Addition of clonidine to lignocaine 0.5% at end of surgery under IVRA did not significantly improve duration and quality of post operative analgesia or tourniquet pain.
