In this study, we aimed to investigate the impact of supplementing ropivacaine with dexmedetomidine in ultrasound-guided continuous pericapsular nerve group block (PENGB) among elderly patients undergoing THA. We conducted a retrospective analysis involving 112 elderly patients who underwent THA. These patients were divided into two groups: the Control group, receiving ropivacaine alone, and the DEX group, receiving ropivacaine combined with dexmedetomidine. We evaluated various parameters including hemodynamic data, postoperative pain levels assessed using the Visual Analog Scale, cognitive status measured with the Montreal Cognitive Assessment, and serum markers (S100\u03b2 and GFAP). Our findings revealed that the DEX group exhibited improved stability in blood pressure and oxygen saturation following surgery. Moreover, patients in the DEX group reported significantly lower levels of pain at 6 and 12 hours postsurgery, with a prolonged duration of pain relief. Furthermore, dexmedetomidine administration was associated with preserved cognitive function during the early postoperative period. Analysis of serum markers suggested potential cognitive protection conferred by the addition of dexmedetomidine. Overall, our study underscores the multifaceted benefits of incorporating dexmedetomidine into ropivacaine-based PENGB for elderly THA patients.<\/jats:p>","DOI":"10.1089\/rej.2024.0014","type":"journal-article","created":{"date-parts":[[2024,4,27]],"date-time":"2024-04-27T08:18:08Z","timestamp":1714205888000},"page":"115-121","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Effects of Dexmedetomidine Added to Ropivacaine in Ultrasound-Guided Continuous Pericapsular Nerve Group Block Among Elderly Patients Undergoing Total Hip Arthroplasty"],"prefix":"10.1177","volume":"27","author":[{"given":"Xia","family":"Li","sequence":"first","affiliation":[{"name":"Department of Anesthesiology, The Second People\u2019s Hospital of Hefei, Hefei Hospital Affiliated to Anhui Medical University, Hefei, China."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liang","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, The Second People\u2019s Hospital of Hefei, Hefei Hospital Affiliated to Anhui Medical University, Hefei, China."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yunyun","family":"Sun","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, The Second People\u2019s Hospital of Hefei, Hefei Hospital Affiliated to Anhui Medical University, Hefei, China."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuanhai","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, The First Affiliated Hospital of Anhui Medical University, Hefei, China."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2024,8,14]]},"reference":[{"key":"e_1_3_6_2_2","doi-asserted-by":"publisher","DOI":"10.1503\/cjs.007214"},{"key":"e_1_3_6_3_2","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.99B6.38053"},{"key":"e_1_3_6_4_2","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.RVW.16.00002"},{"key":"e_1_3_6_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ienj.2021.101012"},{"key":"e_1_3_6_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.otsr.2021.103135"},{"issue":"1","key":"e_1_3_6_7_2","article-title":"Ultrasound-guided pericapsular nerve group block for hip surgery: A randomized controlled trial study comparing ropivacaine and ropivacaine with dexamethasone","volume":"15","author":"Balasubramaniam A","year":"2023","unstructured":"Balasubramaniam A, , Kumar Naggaih S, , Tarigonda S, , Madhusudhana R.
