双胎有胎内输血者占单卵双胎的17.29％,其中血红蛋白相差最多11g,10对中第一孩低于第二孩的有9例;双头位4对血红蛋白平均差5.62g,头臀位6对血红蛋白平均差7.41g,头臀位分娩血红蛋白差高于双头位,双胎輸血可因一胎盘的动脉连接到另一胎盘的静脉或分娩过程中第一胎受产道挤压所致,本文10对多数为后一因素造成.为防止双胎输血:①第一孩断脐前位置不能高于胎内孩;②第一孩娩出后不宜过早断脐。输血者血红蛋白低于13g需输血,受血者要防止高胆红质血症。
Twins have intra-fetal transfusions accounted for 17.29% of monozygotic twins, of which hemoglobin difference of up to 11g, 10 pairs of the first child is lower than the second child in 9 cases; double-headed 4 pairs of hemoglobin average difference of 5.62g, the buttocks Bit 6 of hemoglobin average difference 7.41g, head breech hemoglobin delivery is higher than the double-headed bit, twins blood transfusion can be due to a placental artery connected to another placental vein or the first child during delivery due to birth canal extrusion , This article is mostly caused by the latter factor 10. In order to prevent twin blood transfusions: ① the first child off the umbilicus before the position can not be higher than the child; ② after the first child should not be too early to break the umbilical cord. Transfusion hemoglobin less than 13g need blood transfusion, blood recipients to prevent hypercalanophilia.
