In two cases, fetal bradycardia necessitated delivery by Caesarean section at 30 and 32 weeks' gestation, respectively. In the third case, fetal bradycardia developed during transfusion, at 31 weeks' gestation, but normalized within 3 min. The baby was delivered as planned at 36 weeks of gestation, after another transfusion at 34 weeks. Dislodgement of the needle tip into perivascular tissue, caused by sudden fetal or maternal movements, is the reason for this complication. The haematoma develops as a result of delayed recognition and continuous transfusion into Wharton' s jelly. Cord haematoma may be diagnosed in time by continuous ultrasound imaging, as illustrated in case 3.<\/jats:p><jats:p>To minimize the risk of needle dislodgement during transfusion, sedation of the mother and complete immobilization of the fetus by injecting a short\u2010acting muscle relaxant into the umbilical vessel are recommended.<\/jats:p>","DOI":"10.1002\/pd.1970100109","type":"journal-article","created":{"date-parts":[[2007,3,3]],"date-time":"2007-03-03T23:09:17Z","timestamp":1172963357000},"page":"59-65","source":"Crossref","is-referenced-by-count":17,"title":["Umbilical cord haematoma as a complication of intrauterine intravascular blood transfusion"],"prefix":"10.1002","volume":"10","author":[{"given":"Georg","family":"Keckstein","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sonja","family":"Tschurtz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Volker","family":"Schneider","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wolfgang","family":"M\u00fctter","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rainer","family":"Terinde","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wolf\u2010Dietrich","family":"Jonatha","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,11,21]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.284.6313.373"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9378(87)80333-2"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(86)90282-6"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(88)90052-X"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(88)90804-6"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9378(85)80254-4"},{"key":"e_1_2_1_8_1","first-page":"529","article-title":"Ultrasound\u2010guided fetal blood transfusion for severe rhesus iso\u2010immunisation","volume":"66","author":"de Crespigney C.","year":"1985","journal-title":"Obstet.
