ABSTRACT Introduction This prospective, randomized, double-blind study compared the onset and duration of sensory blockade, motor blockade, and analgesia with lignocaine, bupivacaine, and midazolam combination vs only lignocaine, bupivacaine in brachial plexus block. Materials and methods Patients of either sex, aged 18–60 years, American Society of Anesthesiologists grade I/II, posted for upper limb surgeries to be performed under supraclavicular brachial plexus block with the help of peripheral nerve stimulator were administered either 10 ml 0.5% bupivacaine with 50 μg/kg midazolam (preservative free) + 20 ml 2% lignocaine with adrenaline (1:200,000) in Group lignocaine– bupivacaine–midazolam (LBM) or 10 ml 0.5% bupivacaine + 20 ml 2% lignocaine with adrenaline (1:200,000) in Group lignocaine–bupivacaine (LB). Onset and duration of sensory and motor blockade were monitored. Postoperative analgesia was graded with visual analog scale. Sedation was monitored with Ramsey sedation score. Results A total of 60 patients were randomized to the group LBM (n = 30) and group LB (n = 30). The analgesia was significantly prolonged in the study group, with a mean of 11.72 ± 1.924 hours as compared with a mean of 6.383 ± 1.031 hours in the control group. Sedation scores were higher in the study group, that is, group LBM compared to group LB postoperatively. Conclusion In conclusion, midazolam when added to bupivacaine and adrenalized lignocaine for supraclavicular brachial plexus block hastens the onset of sensory and motor blockade. This combination improves analgesia, as manifested by lower pain scores and prolonged duration of analgesia. How to cite this article Dalvi NP, Salunkhay H, Mohite SN.

Introduction: Dexmedetomidine has been frequently used in regional anaesthesia to improve the quality of blocks. Addition of dexmedetomidine to local anaesthetics has been shown to hasten the onset of both sensory and motor blocks and also prolong the duration of analgesia. The objective of this prospective comparative study was to assess the change in characteristics of infraclavicular brachial plexus block after adding Inj. Dexmedetomidine to 2% Lignocaine with Adrenaline. Methods: Sixty-six patients, scheduled for upper limb surgeries under ultrasound guided infraclavicular brachial plexus block were randomly allocated to two groups. Group LS received Inj. Lignocaine 2% with Adrenaline, 7mg/kg diluted to 30 ml with saline and Group LD received Inj. Dexmedetomidine 0.75 mcg/kg in addition to Inj. Lignocaine 2% with Adrenaline, 7mg/kg again diluted to a total volume of 30 ml. The parameters studied were: onset of sensory and motor blocks and duration of analgesia. Results: Sixty patients completed the study. The demographic variables and motor block were similar between both groups. The mean time to onset of sensory block was significantly faster in Group LD compared to Group LS (9.80±4.85 min vs 12.30±3.97 min, p=0.033). The duration of analgesia was also found to be prolonged in Group LD compared to Group LS (286.73±55.38 min vs 226.53±41.19 min, p < 0.001). Conclusion: Addition of 0.75 mcg/kg of Dexmedetomidine to 2% Lignocaine with Adrenaline hastens the onset of sensory block and prolongs the duration of analgesia in ultrasound guided and peripheral nerve stimulator guided infraclavicular block.
