| pubmed-article:2714506 | pubmed:abstractText | Plasma fibrinopeptide A (FPA), a dynamic measure of intravascular coagulation, was determined in 70 healthy Chinese women during normal pregnancy, labour, delivery and the early puerperium and compared to a group of healthy non-pregnant adult controls. In the normal controls the plasma FPA level (mean +/- SD) was 1.43 +/- 0.46 ng/ml. During pregnancy and labour, the FPA levels were 3.05 +/- 0.98 ng/ml and 11.47 +/- 4.43 ng/ml, respectively, and it reached a peak of 32.95 +/- 11.66 ng/ml at parturition, then falling to 6.15 +/- 2.52 ng/ml in the early puerperium. All these levels were significantly higher (p less than 0.001) compared to controls. Fifteen of the 21 mothers with blood sampling during parturition also had umbilical cord blood taken for determination of FPA level. There was no significant difference between the maternal (34.07 +/- 10.12 ng/ml) and cord (31.06 +/- 12.67 ng/ml) plasma FPA levels. It is concluded that the hypercoagulable state in women during pregnancy and the puerperium is associated with increased intravascular coagulation activity, and that increased intravascular coagulation activity also occurs in the fetus during parturition. This observation may account for the increased risk of thrombotic disorders observed in pregnant and parturient women as well as in the newborn. | lld:pubmed |
