Abstract
BACKGROUND: Regional anesthesia can be used as part of the anesthetic to optimize anesthesia and analgesia during shoulder arthroplasty, but little is known about the overall effect that regional anesthesia has on perioperative outcomes and resource utilization. We hypothesized that regional anesthesia may decrease complication rates and resource utilization in shoulder arthroplasty patients. METHODS: We examined administrative data from 588 US hospitals from 2010 to 2015. Logistic regression was used to examine the relationship between type of anesthesia and perioperative complications. RESULTS: Among patients who underwent shoulder arthroplasty, 79.1% (53,243) had general anesthesia alone, 17.8% (12,011) had general anesthesia and a nerve block, and 3.1% (2062) had a nerve block alone. Overall, the complication rate was 13.3% and 30-day mortality was 1.2 per 1000 (95% CI 0.9, 1.4). In adjusted analyses, patients who had general anesthesia alone (compared to general anesthesia and nerve block) had a 16% increase in all cause infectious complications (OR 1.16, 95% CI: 1.03, 1.31) and were 2.6 times more likely to develop pulmonary complications (OR 2.6, 95% CI: 1.14, 5.78). General anesthesia alone (relative to either block only or general anesthesia and block) was associated with substantial increases in the likelihood of blood transfusions, intensive care unit transfers, and prolonged length of stay. CONCLUSION: Patients receiving regional anesthesia for shoulder arthroplasty may have a reduction in perioperative complications, the need for intensive care unit transfers, blood transfusions, and prolonged hospital stays.
