Because of refusal of invasive monitoring, thoracic electrical bioimpedance (TEB) was performed to evaluate cardiac function and volume status. TEB pointed out decreased cardiac output (CO: 4.23 liters\/min), cardiac index (CI: 2.63) and stroke volume (SV: 57.5 ml\/beat). Serial monitoring of hemody-namic variables was then performed. After the data were obtained, fluid management was performed, and the patient recovered from abnormal homeostasis in 3 days. The hemodynamic variables returned to the normal range (CO: 6.85 liters\/min, CI: 4.25, SV: 100.5 ml\/beat) within the first 24 h. There were no complications such as life-threatening multiple organ failure. We discuss the usefulness of TEB for the fluid management of severe OHSS, as well as its implications.<\/jats:p>","DOI":"10.1159\/000292061","type":"journal-article","created":{"date-parts":[[2010,3,1]],"date-time":"2010-03-01T04:20:08Z","timestamp":1267417208000},"page":"140-142","source":"Crossref","is-referenced-by-count":0,"title":["Cardiac Output Measurement by Thoracic Electrical Bioimpedance in a Patient with Ovarian Hyperstimulation Syndrome"],"prefix":"10.1159","author":[{"given":"Kanji","family":"Ryuko","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kentaro","family":"Takahashi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masako","family":"Okada","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naomi","family":"Tamaru","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manabu","family":"Kitao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2010,2,26]]},"container-title":["Gynecologic and Obstetric Investigation"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000292061","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T06:08:26Z","timestamp":1777615706000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000292061"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,2,26]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000292061","archive":["Portico"],"relation":{},"ISSN":["0378-7346","1423-002X"],"issn-type":[{"value":"0378-7346","type":"print"},{"value":"1423-002X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,2,26]]}}}
