Purpose: The purpose of this study is to analyse the safety and success of combined interscalene-cervical plexus block as a sole anesthesia method for Acromioclavicular joint fixation retrospectively. Methodology: We retrospectively analysed and present a case series of acromioclavicular joint fixation surgery that were operated under combined interscalene-cervical plexus blockbetween Jan 2017 and Dec 2018 in our institute. Block success, any complications as inadvertent arterial puncture, hematoma formation, respiratory distress, Horner’s syndrome, pneumothorax, and signs of local anesthetic toxicity from the records were evaluated. Any conversion to general anesthesia, intra-operative anesthetic supplementation and time to receive first dose of analgesics also analysed from the records. Results: After exclusion 32 patients were analysed and found 100% block success rate. None of them required conversion to general anesthesia. In our study, four patients developed hoarseness of voice (12.50%), and three patients complained of breathing difficulty (9.38%). No other major complications. Conclusion: The ultrasound guided combined interscalene and cervical plexus block able to provide a successful, safe and effective sole anesthesia technique for acromioclavicular reconstruction surgeries without major complications. Prospective comparative study would prove that it can be an alternate method over general anesthesia.
