Multimodal Pain Management Protocol Versus Patient Controlled Narcotic Analgesia for Postoperative Pain Control after Shoulder Arthroplasty

  Background: Our institution’s traditional pain management strategy after shoulder arthroplasty has involved the utilization of postoperative patient-controlled narcotic analgesia. More recently, we have implemented a protocol (TLC) that utilizes a multimodal approach. The purpose of this study was to determine whether this change has improved pain control and decreased narcotic utilization. Methods: Patients undergoing primary total shoulder or reverse arthroplasty were retrospectively studied. All patients underwent interscalene brachial plexus blockade. “Traditional” patients were provided a patient-controlled analgesic pump postoperatively. TLC patients were given preoperative and postoperative multimodal, non-narcotic analgesic medications and breakthrough narcotics. Morphine equivalent units (MEU) consumed and Visual Analog Scale (VAS) scores for pain (0, 8, 16, and 24 hours) were considered. Results: There were 108 patients in each group. Total postoperative narcotic consumption in the first 24 postoperative hours was 38.5 +/- 81.1 MEU in the “Traditional group” compared to 59.3 +/- 59.1 MEU in the TLC group (P
