Clinical decision-making should prioritize position selection based on specific cardiovascular risk factors, with the lateral decubitus position recommended for patients with pre-existing cardiovascular disease, uncontrolled hypertension, or age over 70 years.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fsurg.2026.1687643","type":"journal-article","created":{"date-parts":[[2026,8,11]],"date-time":"2026-08-11T12:35:26Z","timestamp":1786451726000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Effect of beach chair position on hemodynamics and cardiovascular events in patients undergoing shoulder arthroscopy for rotator cuff injury combined with shoulder adhesion"],"prefix":"10.3389","volume":"13","author":[{"given":"Yuxin","family":"Zhang","sequence":"first","affiliation":[{"name":"Anaesthesiology, Jiashan First People's Hospital Maternal and Child Health Hospital","place":["Zhejiang, Jiashan, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ling","family":"Zhao","sequence":"additional","affiliation":[{"name":"Anaesthesiology, Jiashan First People's Hospital Maternal and Child Health Hospital","place":["Zhejiang, Jiashan, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jidong","family":"Lv","sequence":"additional","affiliation":[{"name":"Anaesthesiology, Jiashan First People's Hospital Maternal and Child Health Hospital","place":["Zhejiang, Jiashan, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jie","family":"Lei","sequence":"additional","affiliation":[{"name":"Anaesthesiology, Jiashan County Maternal and Child Health Hospital","place":["Zhejiang, Jiashan, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,8,11]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"4475087","DOI":"10.1155\/2022\/4475087","article-title":"Effect of arthroscopic acromioplasty combined with rotator cuff repair in the treatment of aged patients with full-thickness rotator cuff tear and rotator cuff injury","volume":"2022","author":"He","year":"2022","journal-title":"Emerg Med Int"},{"key":"B2","doi-asserted-by":"publisher","first-page":"e585","DOI":"10.1016\/j.jse.2024.02.032","article-title":"Effects of arthroscopic rotator cuff repair on isokinetic muscle function 6 months following surgery: influence of tear type, tear size, and tendon retraction","volume":"33","author":"Drewitz","year":"2024","journal-title":"J Shoulder Elbow Surg"},{"key":"B3","doi-asserted-by":"publisher","first-page":"e74988","DOI":"10.7759\/cureus.74988","article-title":"A narrative review of rotator cuff tear management: surgery versus conservative treatment","volume":"16","author":"Altamimi","year":"2024","journal-title":"Cureus"},{"key":"B4","doi-asserted-by":"publisher","first-page":"196","DOI":"10.23750\/abm.v91i4-S.9591","article-title":"Two rotator cuff tear repair techniques for sovraspinatus tendon tear: transosseous sharc-ft vs single row repair","volume":"91","author":"Pellegrini","year":"2020","journal-title":"Acta Biomed"},{"key":"B5","doi-asserted-by":"publisher","first-page":"375","DOI":"10.1136\/jisakos-2020-000553","article-title":"Acute massive rotator cuff rupture with posterior shoulder dislocation: arthroscopic novel repair of a rare injury.
