Comparative study of clonidine and dexmedetomidine used as adjuvant to epidural ropivacaine in orthopaedic lower limb surgery (original) (raw)

Background: A lot of researches have been done to find an ideal adjuvant to ropivacaine in regional anaesthesia that inhibits intra and post operative pain and prolong the duration of anaesthesia without any side effects. was conducted to evaluate th dexmedetomidine when used as an adjuvant to ropivacaine in epidural anaesthesia in lower limb orthopaedic surgery. Materials and Methods: A prospective randomized stu anaesthesiologists' status I and II, posted for lower limb orthopaedic surgery. All patients were randomly allocated into two groups of 30 each; group I was ropivacaine group (RD). Group I (RC) patients received 16 ml of 0.75% ropivacaine and clonidine 2mcg/kg. Group II (RD) patients received 16 ml of 0.75% ropivacaine and dexmedetomidine 1.5mcg/kg. The onset, extent, duration of sens blocks, and side effects were recorded. earlier onset and longer duration of sensory and motor block. Sedation scores were statistically significant with RD group in comparison to RC group. RD group showed visible superiority over RC group in various post characteristics like the weaning of sensory and motor block, prolonged post Dexmedetomidine was a better alternative orthopaedic lower limb surgeries.
