【 摘 要 】

Background & Objective: Regional anesthesia (RA) blocks are most commonly performed in large academic hospitals and has been shown to reduce postoperative pain. The lack of RA blocks in rural hospitals leaves a large subset of the population without availability of this service. In North Carolina, there is an increased need for these services in small community hospitals. This study examined RA nerve block success rates for total knee, hip, and shoulder arthroplasty procedures. We hypothesized that through proper mentorship, general anesthesiologists could provide safe and efficacious RA blocks at a small, community hospital.Methodology: An Institutional Review Board (IRB) approved retrospective study was performed at Lexington Medical Center (LMC), in Lexington, North Carolina part of Wake Forest Baptist Health. We analyzed 307 patients who underwent total joint arthroplasty (195 knee, 69 hip and 43 shoulder replacements) at LMC. Demographics, type of blocks, block success, and intraoperative analgesics used were also recorded. VAS was used to assess postoperative pain.Results: We found an overall success rate of 96.3% for all joints; 95.2%-femoral or 98.9%-adductor canal, 90.4%-lumbar plexus, 100%-interscalene block for knee, hip and shoulder arthroplasties respectively. 283/307 (92.2%) patients reported a verbal pain score between 0-2 in the PACU. There was a significantly higher mean fentanyl dose/h in patients that did not receive a lumbar plexus block for hip procedures.Conclusion: The results of our study support that general anesthesiologists can provide rural communities with quality, specialized regional anesthesia care safely, and at an equivalent level to that of anesthesiologists specialized in RA blocks at large academic institutions.
