The patients were divided into low-noise group (\u226452\u2009dB[A]), medium-noise group (53\u201358\u2009dB[A]), and high-noise group (\u226559\u2009dB[A]) according to the noise exposure tripartite. The PACU immediate numeric rating scale (NRS) score was used as the primary outcome measure, and a multiple linear regression model was used to analyze the relationship between noise exposure and pain score, adjusting for potential confounders.\n                    <jats:bold>Results:<\/jats:bold>\n                    No significant differences were observed in baseline demographic characteristics and perioperative indicators between the three groups (all\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    &gt; 0.05). There was a statistically significant difference in the postoperative acute pain NRS scores among patient subgroups with different levels of environmental noise exposure in the PACU (\n                    <jats:italic toggle=\"yes\">P\u2009<\/jats:italic>\n                    =\u20090.002). After adjusting for confounding factors, multiple linear regression analysis showed that PACU environmental noise exposure was significantly positively correlated with postoperative acute pain scores, with an average increase of 0.07-points (95% CI: 0.03\u20130.11,\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    &lt; 0.001) for every 1 dB(A) increase in noise level. The association remained stable after correcting for confounders, showing a clear dose\u2013response relationship.\n                    <jats:bold>Conclusion:<\/jats:bold>\n                    The level of PACU environmental noise exposure is significantly correlated with acute postoperative pain severity in patients undergoing hip arthroplasty under general anesthesia. This study provides clinical evidence for the health effects of the hospital acoustic environment; it can help improve patients\u2019 perioperative experience and quality of rehabilitation.\n                  <\/jats:p>","DOI":"10.4103\/nah.nah_57_26","type":"journal-article","created":{"date-parts":[[2026,9,2]],"date-time":"2026-09-02T10:02:56Z","timestamp":1788343376000},"page":"923-929","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Association Analysis of Background Noise Exposure in the Postanesthesia Care Unit and Postoperative Acute Pain in Patients Undergoing Hip Arthroplasty Under General Anesthesia"],"prefix":"10.4103","volume":"28","author":[{"given":"You","family":"Lv","sequence":"first","affiliation":[{"name":"Department of Anesthesiology, Xuzhou No. 1 People\u2019s Hospital, Xuzhou 221116, Jiangsu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Su","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Xuzhou No. 1 People\u2019s Hospital, Xuzhou 221116, Jiangsu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"XiaoQing","family":"Shao","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Xuzhou No. 1 People\u2019s Hospital, Xuzhou 221116, Jiangsu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"NingNing","family":"Ji","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Xuzhou No. 1 People\u2019s Hospital, Xuzhou 221116, Jiangsu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"XingDui","family":"Ma","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Xuzhou No. 1 People\u2019s Hospital, Xuzhou 221116, Jiangsu, China"},{"name":"Department of Anesthesiology, The Affiliated Xuzhou Municipal Hospital of Xuzhou Medical University, Xuzhou 221116, Jiangsu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2026,8,31]]},"reference":[{"key":"R1-20260908","first-page":"651","article-title":"The Joint Surgery Branch of the Chinese Orthopaedic Association, 920th Hospital of Joint Logistics Support Force of Chinese People\u2032s Liberation Army.
