    BackgroundAlternative techniques have been developed to address pain after shoulder arthroplasty and are well documented. We evaluated the effect of adding intraoperative liposomal bupivacaine and intravenous dexamethasone during shoulder arthroplasty.MethodsWe retrospectively reviewed 2 consecutive cohorts undergoing elective shoulder arthroplasty. The 24 patients in cohort 1 and the 31 patients in cohort 2 received perioperative multimodal management with preoperative and postoperative intravenous and oral narcotics, gabapentin, nonsteroidal anti-inflammatory drugs, acetaminophen, and single-injection interscalene block. Cohort 2 also received 8 to 10 mg of intravenous dexamethasone intraoperatively after the skin incision and liposomal bupivacaine injected at surgery. Patients who did and did not use preoperative narcotics were analyzed together and separately. We evaluated hospitalization length of stay, narcotic use, and visual analog scale pain before and after the change in the perioperative protocol.ResultsCohort 1 was hospitalized longer (2 vs. 1 day; P < .001), required more narcotics on postoperative day 1 (21.0 vs. 10.0 mg; P < .001) and days 0 and 1 cumulatively (30.5 vs. 17.5 mg; P = .001), and had more pain on postoperative days 0 (6.5 vs. 3.5; P < .001) and 1 (7.5 vs. 3.5; P < .001) than cohort 2. In patients using preoperative narcotics, cohort 2 had less pain on postoperative day 1 (3.5 vs. 7.0; P = .006), less cumulative narcotic use (20 vs. 58.5 mg; P = .03), and shorter hospitalization (1 vs. 2 days; P = .052) than cohort 1.ConclusionThese changes to the perioperative shoulder arthroplasty protocol decreased hospitalization length of stay, narcotic requirement, and pain.Copyright © 2017 Journal of Shoulder and Elbow Surgery Board of Trustees.
