Effect of Adding Dexmeditomidine to Levobupivacaine in Supraclavicular Brachial Plexus Block- A Randomized, Controlled Study
Journal Title: International Journal of Medical Science and Innovative Research (IJMSIR) - Year 2018, Vol 3, Issue 4
Abstract
Background and Aims: Various drugs are used with local anaesthetics for upper limb surgeries and postoperative analgesia. We experimented the effect of addition of dexmedetomidine with levobupivacain in supraclavicular brachial plexus block with respect to onset & duration of sensory and motor blockade and duration of analgesia. Material and Methods A total of 60 patients of ASA grade I and II, aged 18-60 yrs of either sex scheduled for upper limb surgeries under supraclavicular brachial plexus block were divided into 2 equal groups in a randomized pattern. Patients in group L (n = 30), received 30 ml of 0.5% levobupivacaine with 1ml normal saline (control) and in group LD (n = 30), received 30 ml of 0.5% levobupivacaine with 1 ml (100µg) dexmedetomidine. The onset and duration of sensory and motor block & duration of analgesia were analyzed in both groups. Statistical analysis done with SPSS 17 software and p value <0.05 taken as significant. Results The mean time of onset of sensory & motor blockade were 12.43±2.56 min and 17.96±3.05 min in group L and 8.13±2.51 min &12.13 ± 2.89 in group LD respectively. The durations of sensory and motor block were 660.16 ± 44.28 and 535.33 ± 50.66 min respectively in group L, whereas they were 930.66 ± 48.02 and 811.83±52.08 min respectively in group LD. The duration of analgesia was 728.86 ± 45.12 min in group L compared to1159.8 ± 56.84 min in group LD (p < 0.001). There was statistically significant difference present in onset and duration of sensory and motor blockade and duration of analgesia between 2 groups. Conclusion Addition of dexmedetomidine in supraclavicular brachial plexus block with levobupivaicane decrease the onset of sensory and motor block and increase the duration of sensory and motor block with prolonged duration of analgesia .
