UNASSIGNED: This is a retrospective trial of adult patients without major comorbidities undergoing elective, upper arm orthopedic procedures with regional nerve block for post-operative analgesia. Patients underwent nerve block with either 0.5% ropivacaine or 0.2% ropivacaine with 5mg dexamethasone and 25mg dexmedetomidine ("dex-dex"). Patients were assessed in 1-week intervals for two weeks for duration of block analgesia, pain scores, and opioid use.
UNASSIGNED: 31 patients were included, 12 controls and 19 in the dex-dex group. These patients underwent one of arthroscopic rotator cuff repair, reverse total shoulder repair or repair of humerus fractures. Dex-dex blocks provided significantly longer analgesia (median block time 3.5 versus 1.5 days, p<0.0001), significantly better analgesia (mean NRS 2.32 versus 8.58 on post-operative day 1, p<0.0001), and significantly reduced opioid requirements (108.16mg vs 275.63mg in MME, p<0.0001). One patient experienced transient hypotension and prolonged paresthesia in the dex-dex group.
UNASSIGNED: Preoperative single-shot interscalene nerve blocks with preservative-free dexamethasone and dexmedetomidine added as adjuvants to ropivicaine provide approximately two additional days of benefit versus ropivicaine alone. Additionally, postoperative opioid consumption is reduced.
