 Scientific or Scholarly Rationale Peripheral nerve blocks have been well studied in the literature with generally good results for controlling post operative pain following orthopaedic surgery 1-4. Regional anesthesia has many benefits. It provides excellent intraoperative anesthesia and muscle relaxation as well as analgesia that continues into the post-operative period. Airway manipulations are avoided, post-operative nausea and vomiting are diminished, post-anesthesia care unit stay are shortened, and fewer nursing interventions in the post-anesthesia care unit are required5-6.
