Evaluation of ultrasound guided supraclavicular block with traditional methods and perfusion index on upper extremity surgeries

Introduction: Ultrasound (USG) guided supraclavicular block in upper extremity surgery is a popular approach. In recent years, many studies have been published on the perfusion index (PI) in the evaluation of block success. The main objective of this study is to evaluate the success and efficiency of the supraclavicular block with traditional methods (Pin-prick test, Modified Bromage Scale) and perfusion index.
