Patients were divided into a normal-to-mild brain injury group (20/33) and a moderate-to-severe injury group (13/33). Compared with the normal-to-mild injury group, moderate-to-severe brain injury was associated with lower minimum regional cerebral oxygen saturation (rSc o2 ; median 20% vs. 46%; p = 0.016), longer duration with rSc o2 less than 50% (median, 48.0 vs. 3.5 hr; p = 0.029), prolonged periods of rSc o2 decline greater than 20% from baseline (median 80.0 vs. 20.0 hr; p = 0.027), and higher cumulative hypoxia burden (median, 407.0 vs. 6.0%·hr; p = 0.034). The receiver operating characteristic curve analysis identified thresholds associated with moderate-to-severe brain injury as follows: minimum rSc o2 of 21%, duration of rSc o2 less than 50% of 44 hours, duration of rSc o2 decline greater than 20% of 46 hours, and cumulative hypoxia burden of 320%·hours.</p><p><strong>Conclusions: </strong>In this 2018-2024 cohort, cerebral NIRS parameters were associated with moderate-to-severe brain injury identified using MRI and HUS. Lower rSc o2 and greater desaturation exposure were associated with the presence of moderate-to-severe injury by discharge. The potential for early risk stratification of neonates on ECMO requires confirmation in prospective studies.</p>","PeriodicalId":19760,"journal":{"name":"Pediatric Critical Care Medicine","volume":" ","pages":"1096-1105"},"PeriodicalIF":4.9,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148157332","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
