Abstract

Context: Various adjuvants have been used with Ropivacaine in supraclavicular blocks to enhance sensory and motor block along with prolongation of postoperative analgesia.

Aim: To compare the effect of dexmedetomidine and clonidine as adjuvant to 0.5% ropivacaine in supraclavicular brachial plexus block with respect to onset and duration of sensory and motor block and duration of analgesia.

Methods and Material: After ethical committee’s approval, a prospective randomised study of 60 patients aged1860 years were randomly divided into two groups (Group C and Group D) of 30 each. Group C received 50mcg clonidine with ropivacaine (29ml), Group D received 50mcg dexmedetomidine with ropivacaine (29ml), via supraclavicular approach. Onset and duration of sensory and motor block and duration of analgesia in both groups were evaluated. Intraoperative hemodynamics and adverse effects were observed.

Statistical Analysis: Numericalvariables were presented as mean & standarddeviation while categoricalvariables were presented as frequency and percent. For analysis, unpaired student ttest and chisquare test were used.

Results: Early onset and prolonged duration of sensory and motor block and prolonged duration of analgesia was seen in group D, as compared to group C.

Conclusion: Dexmedetomidine produces rapid onset and prolonged duration of sensory and motor block and also prolonged duration of analgesia with good hemodynamic stability with no side effects as compared to clonidine.
