【 摘 要 】

Aims and objectives: To study the effect of ultrasound guided superficial cervical plexus and interscalene brachial plexus block for clavicular surgery. Methodology: Thirty American Society of Anesthesiologists (ASA) physical status I and II patients undergoing clavicular surgery, ages 20-60 years were selected. All routine non- invasive monitors were applied and IV line was secured. Ultrasound guided superficial cervical plexus block and interscalene brachial plexus block were given. Injection dexmedetomidine 1 µg/kg infusion over 10 min was started. Block efficacy was evaluated. Any complication or side effects were noted. Sedation was assessed using Ramsay sedation score. Perioperative hemodynamics were charted. Duration of motor block was noted as time of shoulder abduction 3cm from time of block. Duration of analgesia was noted as time for first demand of analgesic from time of block. Results: All the thirty patients allowed clavicular surgeries under combined interscalene brachial plexus and superficial cervical plexus block. No major complications and side effects were noted. Conclusion: USG guided combined superficial cervical plexus and interscalene brachial plexus block are effective for clavicular surgery without any major complication and may be used in place of general anesthesia or blocks by other techniques.
