Abstract

Regional Anaesthesia is an excellent choice which provides effective intra &post operative analgesia with a single technique which is being possible due to the availability of long acting amide local anaesthetics like Ropivacaine and by the addition of adjuvants like clonidine and Dexmedetomidine. A good adjuvant must improve the speed of onset, the quality and/ or duration of analgesia with desirable sedation.

Method: 50 patients divided in two groups were studied. Group RC received 19ml of 0.75%Ropivacaine with Inj. clonidine 2μg/kg (made to 1 ml) and Group RD received 19 ml of 0.75% Ropivacaine with inj. Dexmedetomidine 1.5 μg/kg (made to 1 ml) epidurally. The two groups were compared for onset and duration of sensory and motor block, sedation score and haemodynamic stability.

Results: Onset of sensory block was early in dexmeditomidine group. Duration of sensory block and duration of analgesia was prolonged significantly in Dexmeditomidine group as compared to clonidine group. Sedation score was also high in Dexmeditomidine group. There were no significant haemodynamic changes in both the group

Conclusion: Dexmeditomidine with Ropivacaine is a better adjuvant as compared to clonidine with Ropivacaine in respect to early onset and prolonged duration of motor and sensory blockade, haemodynamic stability and satisfactory sedation score.

Keywords: Ropivacaine, Dexmeditomidine, Clonidine, sensory block, motor block, sedation score.
