The purpose of this study was to assess trends in the use of perioperative single and continuous peripheral nerve blocks (PNBs) and their associations with emergency department (ED) visits after arthroscopic rotator cuff repair (RCR) surgery. The authors used a large database from a private insurer to identify patients who received perioperative PNBs for arthroscopic RCR surgeries from 2007 to 2015. They analyzed patient demographics as well as trends in perioperative PNB use.
