We analyzed risk factors for an inaccurate estimation with uni- and multivariate analysis. We compared the obtained Leduc formula with three other published equations. &lt;i&gt;Results:&lt;\/i&gt; Fetal weight and gestational age were risk factors for an inaccurate estimation of the final Hct. Before 32 weeks the estimation of V&lt;i&gt;O&lt;\/i&gt; was 120 ml\/kg instead of 100 ml\/kg. All formulae overestimated the mean expected Hct value. However, expected Hct estimated by Leduc\u2019s formula is the nearest of the observed final Hct. &lt;i&gt;Conclusion:&lt;\/i&gt; Leduc\u2019s equation seems to be accurate, but less so for the youngest fetuses. We propose an adapted formula V&lt;i&gt;O&lt;\/i&gt; according to gestational age and fetal weight estimation.<\/jats:p>","DOI":"10.1159\/000236150","type":"journal-article","created":{"date-parts":[[2009,10,2]],"date-time":"2009-10-02T05:47:33Z","timestamp":1254462453000},"page":"379-384","source":"Crossref","is-referenced-by-count":8,"title":["Fetal Transfusion of Red Blood Cells for Alloimmunization: Validity of a Published Equation"],"prefix":"10.1159","volume":"25","author":[{"given":"Camille","family":"Le Ray","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lynda","family":"Hudon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Line","family":"Leduc","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2009,9,30]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016%2F0029-7844%2896%2900113-5"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1159%2F000020813"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016%2FS0002-9378%2898%2970178-4"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016%2FS0140-6736%2881%2991549-X"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1159%2F000263583"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1159%2F000263335"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1111%2Fj.1471-0528.2002.02025.x"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.ajog.2004.06.063"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016%2FS0301-2115%2800%2900430-9"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1159%2F000021019"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1007%2Fs00404-007-0382-9"}],"container-title":["Fetal Diagnosis and Therapy"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/236150","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/236150","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T18:13:02Z","timestamp":1745431982000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000236150"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009]]},"references-count":11,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2009,9,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000236150","archive":["Portico"],"relation":{},"ISSN":["1015-3837","1421-9964"],"issn-type":[{"value":"1015-3837","type":"print"},{"value":"1421-9964","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009]]}}}
