Blood group genotyping using DNA extracted from fetal tissue is useful to identify fetuses at risk for hemolytic disease of the fetus and newborn (HDFN) due to maternal red cell alloantibodies. Four considerations are important for fetal blood group genotyping.

Fetal blood velocity waveforms
American Journal of Obstetrics and Gynecology, 1978In this paper a method is described for obtaining and characterizing fetal blood velocity waveforms. The signals were recorded with a range-gated Doppler instrument and characterized after spectral analysis. Preliminary observations indicate differences in the waveforms obtained during normal pregnancies compared with some complicated pregnancies.

Fetal scalp blood sampling (FSBS), in conjunction with fetal heart rate monitoring, is a method of fetal surveillance that may avoid cesarean delivery of the healthy fetus or indicate the need for immediate delivery of a compromised fetus. Some researchers have recently begun to question the efficacy of FSBS.

American Journal of Obstetrics and Gynecology, 1960
The normal relationship between fetal and maternal plasma of total osmotic pressures and concentrations of sodium and potassium were determined in women with uncomplicated pregnancies at full term. The total osmotic pressure of fetal plasma was found to be 3.6 mOsm/kg of water higher than the maternal, probably not representing a physiologically ...

Current Opinion in Obstetrics and Gynecology, 1995
Fetal cells have been successfully detected in maternal blood in all three trimesters of gestation in a substantial proportion of normal pregnancies. Various enrichment techniques have been developed for fetal trophoblast cells, leucocytes and nucleated red blood cells. Nucleated red blood cells are considered to be best suited for noninvasive prenatal

Fetal blood sampling under ultrasound guidance has permitted the opening of the fetal vascular compartment for diagnosis and therapy. Under very strict conditions, this procedure allows the clinician to use fetal blood analysis as a complementary routine examination.

Fetal Blood Sampling and Fetal Thrombocytopenia
Fetal Diagnosis and Therapy, 1995The purpose of this investigation is to determine whether fetal thrombocytopenia is a risk factor for puncture site bleeding. Three groups of fetuses either with or at known risk for thrombocytopenia were identified from a prospectively maintained data base of 1,100 procedures: alloimmune thrombocytopenia (ATP, 29 cordocenteses); unexpected ...

Les auteurs indiquent la technique d'etude de l'irrigation cerebrale du fœtus par examen Doppler ainsi que les differents parametres modifiant l'enregistrement: mouvements respiratoires du fœtus, son etat d'activite, l'activite cardiaque et les stimulations acoustiques.

Ultrasound-guided fetal blood transfusions allow precise assessment and rational treatment of the anemic fetus. Outcome improves for all such fetuses, but particularly in the hydropic, moribund group.

Fetal blood volume restoration following rapid fetal hemorrhage
American Journal of Physiology-Heart and Circulatory Physiology, 1990In a previous study, we found that ovine fetal blood volume returned to normal in 3 h after a slow hemorrhage of 31% over 2 h; volume was slightly elevated at 24-25 h. In the present study, we explored the time required for blood volume restoration in late gestation fetal sheep following a rapid hemorrhage over 10 min.
