Objective:To evaluate the effectiveness and side effects, complications of interscalene brachial plexus block with a nerve stimulator for clavicular fracture surgery. Materials and Methods:In a prospective descriptive study, fifty patients received interscalene brachial plexus block for fixation of clavicle fracture. The dose was 7 mg/kg of 1% lidocaine mixed with 1 : 200000 adrenaline. Results:The success rate was 94%, including 4% of patients needed sedation and small amount of narcotic, failure rate was 6%. The minimal stimulating current of the nerve location was 0.46 ±0.08 mA, the onset time of sensory block was 8.86 ±2.65min. There were 3 complications with one Horner’s syndrome and two hoarsenesses. Conclusion:We found that in patients undergoing fixation of clavicle fracture the interscalene block with a nerve stimulator was an effective anesthetic with a low rate of side effects and complications. Key words:Interscalene block, nerve stimulator, clavicular fracture surgery.

Background: Brachial plexus block via interscalene approach is an excellent option for upper limb surgeries, but due to sparing of ulnar nerve (lower trunk, C8-T1) and its’ complications, it is not so popular. To overcome this problem, interscalene block via lower approach has been tried which has more advantage in view of ulnar nerve blockage and also less complications. In addition, ultrasound provides reliability, ease, rapidity and also patient comfort during block procedure. This prospective study was performed to evaluate the anaesthetic effect of lower approach interscalene block with the help of ultrasound and peripheral nerve stimulator.Methods: Ultrasound guided interscalene brachial plexus block via lower approach was given in randomly selected 30 patients, undergoing upper limb orthopaedic surgeries. After localisation of brachial plexus with ultrasound, the nerve roots were confirmed with the help of peripheral nerve stimulator, before injecting drug. At 5 and 15 min after block, all patients were assessed for the effect. Postoperatively they were assessed for any complication and also for their satisfaction level by Likert’s scale.Results: In territories of ulnar, radial and musculocutaneous nerve there was 100% effect while in median nerve territory 92.8% motor block was there. There was no need of analgesics during intra operative period in any patient and there were no major complications with this approach.Conclusions: Ultrasound guided interscalene block via lower approach is an excellent alternative for upper limb surgeries over classical approach in view of ulnar nerve blockage without any major complication.

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.
