Receiver operating characteristic curve analysis showed that preoperative arterial blood lactate level was a significant predictive biomarker for POD, with an area under the curve of 0.708(95%CI=0.606\u20130.809, P&amp;lt;0.05). Subgroup analysis indicated that high preoperative lactate levels were an independent risk factor for delirium after DBS surgery (OR=10.71,95%CI=1.17\u201397.87, P=0.036) in female Parkinson's disease patients.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Discussion:<\/jats:bold>\n                    Preoperative high level of lactate is an independent factor for delirium after DBS surgery in patients with Parkinson's disease.\n                  <\/jats:p>","DOI":"10.3389\/fragi.2025.1538012","type":"journal-article","created":{"date-parts":[[2025,3,25]],"date-time":"2025-03-25T06:06:07Z","timestamp":1742882767000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Relationship between preoperative high arterial blood lactate level and delirium after deep brain stimulation surgery in Parkinson\u2019s disease"],"prefix":"10.3389","volume":"6","author":[{"given":"Wenbin","family":"Lu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miaomiao","family":"Rao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liangliang","family":"Lu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Panpan","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaorong","family":"Dou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinjun","family":"Bian","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoming","family":"Deng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,3,25]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1175","DOI":"10.3233\/jpd-230276","article-title":"Risk factors for postoperative delirium severity after deep brain stimulation surgery in Parkinson's disease","volume":"14","author":"Astalosch","year":"2024","journal-title":"J.
