While brachial plexus block (BPB) offers analgesic benefits, its additive effect alongside general anesthesia remains underexplored. Materials and Methods: We conducted a retrospective cohort study of adults undergoing open reduction and internal fixation for radius fractures under general anesthesia between July 2020 and September 2025. Patients receiving preoperative ultrasound-guided BPB were matched 1:1 to those without BPB using propensity score matching. Pain scores, hemodynamic changes, and anesthesia-to-incision time were compared using paired t-tests or Wilcoxon signed-rank tests. Perioperative opioid consumption and breakthrough morphine use were analyzed using conditional logistic regression, Kaplan\u2013Meier survival analysis, and stratified Cox regression. Results: Among 707 eligible patients, 205 who received BPB were matched to 205 controls. In the matched cohort (n = 410), BPB was associated with lower intraoperative fentanyl use [16.1% vs. 43.4%; odds ratio (OR) = 0.23; 95% confidence interval (CI): 0.13\u20130.40; p &lt; 0.001], reduced rescue analgesic use in the postanesthesia care unit (10.2% vs. 53.2%; OR = 0.06; 95% CI: 0.03\u20130.16; p &lt; 0.001), and decreased total opioid use (mean morphine milligram equivalents: 2.3 \u00b1 3.4 vs. 6.7 \u00b1 5.6; p &lt; 0.001). Pain scores were lower (visual analogue scale: 2.9 \u00b1 1.4 vs. 3.9 \u00b1 1.9; p &lt; 0.001). Breakthrough morphine use was delayed and less frequent in the BPB group (19.0% vs. 28.3%; hazard ratio = 0.47; 95% CI: 0.29\u20130.78; p = 0.003). BPB attenuated hemodynamic responses (mean arterial pressure area under curve: 707.2 \u00b1 512.5 vs. 979.3 \u00b1 636.5; p &lt; 0.001). Conclusions: Preoperative BPB improves perioperative analgesia, lowers opioid use, and stabilizes hemodynamics in radius fracture surgery.<\/jats:p>","DOI":"10.3390\/medicina62030493","type":"journal-article","created":{"date-parts":[[2026,3,5]],"date-time":"2026-03-05T11:52:11Z","timestamp":1772711531000},"page":"493","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Analgesic and Hemodynamic Effects of Preoperative Ultrasound-Guided Brachial Plexus Block in Radius Fracture Surgery: A Propensity-Matched Cohort Study"],"prefix":"10.3390","volume":"62","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-5705-6920","authenticated-orcid":false,"given":"Wen-Chen","family":"Chao","sequence":"first","affiliation":[{"name":"Department of Anesthesiology, Taipei Tzu Chi Hospital, Buddhist Tzu Chi Medical Foundation, New Taipei City 231, Taiwan"},{"name":"School of Medicine, Tzu Chi University, Hualien 970, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8251-9946","authenticated-orcid":false,"given":"Han-Yu","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Taipei Tzu Chi Hospital, Buddhist Tzu Chi Medical Foundation, New Taipei City 231, Taiwan"},{"name":"School of Medicine, Tzu Chi University, Hualien 970, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5563-2262","authenticated-orcid":false,"given":"Po-Chuan","family":"Yu","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Taipei Tzu Chi Hospital, Buddhist Tzu Chi Medical Foundation, New Taipei City 231, Taiwan"},{"name":"School of Medicine, Tzu Chi University, Hualien 970, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5183-0352","authenticated-orcid":false,"given":"Ping-Cheng","family":"Shih","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Taipei Tzu Chi Hospital, Buddhist Tzu Chi Medical Foundation, New Taipei City 231, Taiwan"},{"name":"School of Medicine, Tzu Chi University, Hualien 970, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8773-1847","authenticated-orcid":false,"given":"Meng-Yu","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Medicine, Tzu Chi University, Hualien 970, Taiwan"},{"name":"Department of Emergency Medicine, Taipei Tzu Chi Hospital, Buddhist Tzu Chi Medical Foundation, New Taipei City 231, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6958-4425","authenticated-orcid":false,"given":"Chun-Yu","family":"Chang","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Taipei Tzu Chi Hospital, Buddhist Tzu Chi Medical Foundation, New Taipei City 231, Taiwan"},{"name":"School of Medicine, Tzu Chi University, Hualien 970, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Rundgren, J., Bojan, A., Mellstrand Navarro, C., and Enocson, A.
