Background: The potential and duration of analgesia can be increased by adding a suitable alpha 2 adrenergic agonists as adjuvants to ropivacaine during elective lower limb surgical procedures under epidural anaesthesia. Still there is a scope for research on the effects of clonidine and dexmedetomidine as potent adjuvants in epidural local anesthetics. The aim of our study is to compare the effect of clonidine and dexmedetomidine when used as an adjuvant to epidural ropivacaine in lower abdominal and lower limb surgeries.
