This study aimed to evaluate the dynamics of CVP under varying conditions, including high mean airway pressure (MAP), persistent pulmonary hypertension of the newborn (PPHN), and treatment with inhaled nitric oxide (iNO) and extracorporeal membrane oxygenation (ECMO).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This retrospective study included 18 neonates diagnosed with HIE, who received brain hypothermia therapy and had umbilical venous catheters (UVC) appropriately placed for CVP monitoring. CVP values were analyzed in relation to high MAP (\u226510\u2005cmH\u2082O), PPHN status, and pre- and post-therapeutic interventions such as iNO and ECMO. Statistical comparisons were performed using Mann\u2013Whitney <jats:italic>U<\/jats:italic> tests for continuous variables, with significance set at <jats:italic>p<\/jats:italic>\u2009&amp;lt;\u20090.05.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Neonates in the high MAP group exhibited significantly higher mean CVP values than those in the normal MAP group (6 vs. 5\u2005mmHg, <jats:italic>p<\/jats:italic>\u2009=\u20090.03). In the PPHN\u2009+\u2009high MAP group, the mean CVP, oxygenation index, and FiO\u2082 levels were markedly elevated compared with the high MAP group without PPHN. iNO administration significantly reduced the mean CVP (7\u2005mmHg pre-iNO vs. 4\u2005mmHg post-iNO, <jats:italic>p<\/jats:italic>\u2009=\u20090.04), whereas VV-ECMO initiation resulted in an increased CVP (mean CVP: 8\u2005mmHg pre-ECMO vs. 13\u2005mmHg post-ECMO, <jats:italic>p<\/jats:italic>\u2009=\u20090.03).<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>CVP monitoring via UVC provides critical information on hemodynamic changes in neonates with HIE, particularly under high MAP and PPHN conditions. While iNO effectively reduced CVP and improved oxygenation, VV-ECMO led to elevated CVP, likely due to the return cannula flow. These findings underscore the need for optimized cannula placement and ventilatory strategies to minimize hemodynamic instability during advanced neonatal therapy.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fped.2025.1611740","type":"journal-article","created":{"date-parts":[[2025,9,11]],"date-time":"2025-09-11T05:25:51Z","timestamp":1757568351000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Central venous pressure dynamics in neonates with hypoxic-ischemic encephalopathy: insights into high mean airway pressure, PPHN, and ECMO management"],"prefix":"10.3389","volume":"13","author":[{"given":"Tomonori","family":"Kurimoto","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tokuhisa","family":"Takuya","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masaya","family":"Kibe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toshio","family":"Harumatsu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroshi","family":"Ohashi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tsuyoshi","family":"Yamamoto","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eiji","family":"Hirakawa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,9,11]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1","DOI":"10.1152\/physrev.1950.30.1.1","article-title":"Functional significance of venous blood pressure","volume":"30","author":"Landis","year":"1950","journal-title":"Physiol Rev"},{"key":"B2","doi-asserted-by":"publisher","first-page":"663","DOI":"10.1016\/S0140-6736(05)17946-X","article-title":"Selective head cooling with mild systemic hypothermia after neonatal encephalopathy: multicentre randomised trial","volume":"365","author":"Gluckman","year":"2005","journal-title":"Lancet"},{"key":"B3","doi-asserted-by":"publisher","first-page":"2085","DOI":"10.1056\/NEJMoa1112066","article-title":"Childhood outcomes after hypothermia for neonatal encephalopathy","volume":"366","author":"Shankaran","year":"2012","journal-title":"N Engl J Med"},{"key":"B4","doi-asserted-by":"publisher","first-page":"e38504","DOI":"10.1371\/journal.pone.0038504","article-title":"Implementation and conduct of therapeutic hypothermia for perinatal asphyxial encephalopathy in the UK\u2014analysis of national data","volume":"7","author":"Azzopardi","year":"2012","journal-title":"PLoS One"},{"key":"B5","doi-asserted-by":"publisher","first-page":"45","DOI":"10.1016\/j.jpeds.2017.12.055","article-title":"Pulmonary hypertension associated with hypoxic-ischemic encephalopathy\u2014antecedent characteristics and comorbidities","volume":"196","author":"Lakshminrusimha","year":"2018","journal-title":"J Pediatr"},{"key":"B6","doi-asserted-by":"publisher","first-page":"e680","DOI":"10.1542\/neo.16-12-e680","article-title":"Persistent pulmonary hypertension of the newborn","volume":"16","author":"Lakshminrusimha","year":"2015","journal-title":"NeoReviews"},{"key":"B7","doi-asserted-by":"publisher","first-page":"873","DOI":"10.1097\/00002480-199339040-00010","article-title":"Extracorporeal membrane oxygenation in term newborns.
