Although calcium is administered to treat citrate transfused during this procedure, the appropriate dose of calcium relative to transfusion volume is unknown.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n \n This retrospective study included neonates (babies under 28 days of age) and infants (babies from 28 days old to less than 1 year old) who underwent MUF during cardiac surgery at our institution in 2\u00a0years. Blood ionized calcium concentration ([Ca\n 2+<\/jats:sup>\n ]) at the end of cardiopulmonary bypass (CPB) (T\n 0<\/jats:sub>\n ), end of administration of FP, PC and CaCl\n 2<\/jats:sub>\n during MUF (T\n 1<\/jats:sub>\n ), and chest closure (T\n 2<\/jats:sub>\n ) were analyzed. Volumes of FP and PC and dose of CaCl\n 2<\/jats:sub>\n administered between T\n 0<\/jats:sub>\n and T\n 1<\/jats:sub>\n and between T\n 1<\/jats:sub>\n and T\n 2<\/jats:sub>\n were examined.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Eight neonates and 45 infants were included. Regression equations for the total transfusion volume (mL) of FP & PC (y) relative to supplemented dose CaCl\n 2<\/jats:sub>\n (mg) (x) were as follows: y = 1.00*x (\n r<\/jats:italic>\n 2<\/jats:sup>\n = 1.00,\n p<\/jats:italic>\n < .001) during MUF, and y = 1.05*x (\n r<\/jats:italic>\n 2<\/jats:sup>\n = 0.76,\n p<\/jats:italic>\n < .001) after MUF. Blood ionized calcium concentrations ([Ca\n 2+<\/jats:sup>\n ]) were within the normal range at both T\n 1<\/jats:sub>\n (end of transfusion during MUF) and T\n 2<\/jats:sub>\n (chest closure).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n \n Administering 20\u00a0mg CaCl\n 2<\/jats:sub>\n per 20\u00a0mL of FP & PC maintains adequate [Ca\n 2+<\/jats:sup>\n ] levels at T\n 1<\/jats:sub>\n and T\n 2<\/jats:sub>\n during cardiac surgery in neonates and infants.\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1177\/02676591251363377","type":"journal-article","created":{"date-parts":[[2025,7,28]],"date-time":"2025-07-28T06:47:52Z","timestamp":1753685272000},"page":"343-350","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Blood ionized calcium concentration following administration of fresh frozen plasma, platelet concentrates and calcium chloride solution during modified ultrafiltration in cardiac surgery for neonates and infants"],"prefix":"10.1177","volume":"41","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-8169-3253","authenticated-orcid":false,"given":"Kouki","family":"Fukuda","sequence":"first","affiliation":[{"name":"Gifu Prefectural General Medical Center"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-8097-0914","authenticated-orcid":false,"given":"Tatsuhiko","family":"Masue","sequence":"additional","affiliation":[{"name":"Gifu Prefectural General Medical Center"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,7,27]]},"reference":[{"key":"e_1_3_7_2_2","doi-asserted-by":"publisher","DOI":"10.1053\/j.jvca.2019.03.036"},{"key":"e_1_3_7_3_2","doi-asserted-by":"publisher","DOI":"10.1177\/02676591211043697"},{"key":"e_1_3_7_4_2","doi-asserted-by":"publisher","DOI":"10.1093\/bja\/aer003"},{"key":"e_1_3_7_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/B978-0-323-42974-0.00012-4"},{"key":"e_1_3_7_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jclinane.2011.10.008"},{"key":"e_1_3_7_7_2","doi-asserted-by":"publisher","DOI":"10.1053\/j.jvca.2022.02.005"},{"key":"e_1_3_7_8_2","first-page":"1546","volume-title":"Miller\u2019s anesthesia","author":"Dudley M","year":"2019","unstructured":"Dudley M, Miller R, Turnbull J.
