The suprascapular nerve block (SSNB) has emerged as an effective regional analgesic alternative. This retrospective cohort study aimed to compare the analgesic efficacy and safety of continuous intra-operative suprascapular nerve block (CI-SSNB) alone versus CI-SSNB combined with fentanyl-based IV-PCA (CI-SSNB + IV-PCA). Methods: A total of 40 patients undergoing ARCR under general anesthesia with a single-shot interscalene block (ISB) were allocated to either CI-SSNB alone (n = 20) or CI-SSNB + IV-PCA (n = 20). Pain scores were assessed using a 0\u201310 visual analog scale from 0 to 72 h postoperatively at predetermined intervals, along with opioid consumption and adverse events. Results: At post-operative day 0 (POD 0, 10 p.m.), mean pain scores were 5.75 \u00b1 2.59 in the CI-SSNB + IV-PCA group vs. 3.95 \u00b1 3.00 in the CI-SSNB group (p = 0.050). The total number of rescue pethidine doses up to post-operative day 3 was 1.80 \u00b1 2.02 vs. 0.95 \u00b1 1.10, respectively (p = 0.108). However, adverse effects such as nausea and vomiting occurred only in the CI-SSNB + IV-PCA group. Conclusions: CI-SSNB provides comparable analgesia to CI-SSNB + IV-PCA, while avoiding IV-PCA-related side effects, suggesting that IV-PCA may not be necessary when CI-SSNB is employed for post-operative analgesia following ARCR.<\/jats:p>","DOI":"10.3390\/jcm14165809","type":"journal-article","created":{"date-parts":[[2025,8,18]],"date-time":"2025-08-18T15:34:53Z","timestamp":1755531293000},"page":"5809","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Comparative Effectiveness of Continuous Intra-Operative Suprascapular Nerve Block (CI-SSNB) with and Without Intravenous Patient-Controlled Analgesia (IV-PCA) on Acute Post-Arthroscopy Pain: A Retrospective Cohort Study"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1740-2984","authenticated-orcid":false,"given":"Sung-yup","family":"Hong","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery, Kangdong Sacred Heart Hospital, Hallym University, Seoul 05355, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dong-woo","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Kangdong Sacred Heart Hospital, Hallym University, Seoul 05355, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-8298-1873","authenticated-orcid":false,"given":"Ji-hun","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Kangdong Sacred Heart Hospital, Hallym University, Seoul 05355, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoon-suk","family":"Hyun","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Kangdong Sacred Heart Hospital, Hallym University, Seoul 05355, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,8,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2325967120970906","DOI":"10.1177\/2325967120970906","article-title":"Suprascapular Nerve Block Is an Effective Pain Control Method in Patients Undergoing Arthroscopic Rotator Cuff Repair: A Randomized Controlled Trial","volume":"9","author":"Kim","year":"2021","journal-title":"Orthop.
