Complications of fetal blood sampling

Article Abstract:

Different complications can develop during fetal blood sampling. Fetal blood sampling involves removal of a sample of blood from the umbilical cord with ultrasonographic guidance. Development of this procedure has enabled prenatal diagnosis and treatment of different diseases. A study reviewed articles published in the medical literature that examined the incidence of complications associated with fetal blood sampling. A variety of factors can increase the risk of complications. These include gestational age, technique, experience of the individual performing the procedure and reasons for carrying out the procedure. Complications that can occur include bleeding, localized accumulation of blood, a transient decrease in fetal heart rate, preterm labor and abruptio placentae, or premature detachment of the placenta. Fetal blood sampling causes many more complications than amniocentesis.

Cervical length in uncomplicated pregnancy: a study of sociodemographic predictors of cervical changes across gestation

Article Abstract:

The cervix appears to shorten significantly as pregnancy progresses in black women, women under stress and women working as skilled manual laborers. This could predispose them to premature birth and could explain why some psychosocial and socioeconomic factors increase the risk of premature birth.

Regulation of plasminogen activator inhibitor 1 expression by interaction of epidermal growth factor with progestin during decidualization of human endometrial stromal cells

Article Abstract:

Epidermal growth factor appears to stimulate the production of plasminogen activator inhibitor in human endometrium in the presence of estrogen. This allows the embryo to attach to the endometrium and establish a connection with the mother's blood vessels without causing excessive bleeding.
