A small sample of fetal blood suitable for studies of haemoglobin synthesis was obtained from a placental vessel under endoscopic visualisation in 23 of 26 patients in whom the procedure was attempted prior to second-trimester abortion. Fetal blood loss, calculated in 23 cases, was between 0-2 ml.

We sought to review indications, technical aspects, risks, and recommendations for fetal blood sampling (FBS).A systematic review was performed using MEDLINE, PubMed, EMBASE, and Cochrane Library using the terms "fetal blood sampling," "percutaneous umbilical blood sampling," and "cordocentesis." The search was restricted to English-language articles ...

Technique and interpretation of results in the acid-base composition of fetal capillary blood is now accepted as a useful index of the fetal well-being during labor; it correlates significantly with the clinical condition of the infant at birth.

Abstract The range of variation in the oxygen dissociation curves of blood of nonpregnant women and of pregnant women has been determined at the same pH—the latter falls within the range of normal nonpregnant individuals. The curves of fetal blood obtained at the end of gestation are to the left of the adult field.

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.

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.
