Whole blood citrate concentration was measured simultaneously in the umbilical vein, fetal femoral artery and maternal artery in seven chronically catheterised pregnant ewes and their fetuses. The mean citrate concentration was 0-321 mmoles/litre in the umbilical vein, 0-297 mmoles/litre in the fetal femoral artery and 0-095 mmoles/litre in the maternal artery. The mean concentration difference for citrate across the fetal placental circulation was 0-024 mmoles/litre but this was not statistically significant (P less than 0-1).
在7只长期插管的妊娠母羊及其胎儿中，同时测量了脐静脉、胎儿股动脉和母体动脉中的全血柠檬酸盐浓度。脐静脉中柠檬酸盐的平均浓度为0 - 321毫摩尔/升，胎儿股动脉中为0 - 297毫摩尔/升，母体动脉中为0 - 095毫摩尔/升。胎儿胎盘循环中柠檬酸盐的平均浓度差为0 - 024毫摩尔/升，但这在统计学上不显著（P小于0 - 1）。
