The assessment of fetal blood samples
American Journal of Obstetrics and Gynecology, 1988Fetal blood sampling under ultrasound control is rapidly expanding the study of human fetal biology. Pure fetal blood is required for prenatal diagnosis, establishment of reference ranges for biologic measurements, and assessment of fetal welfare. We present here the methods that we have developed to detect contamination in more than 1500 samples ...

Complications of fetal blood sampling
American Journal of Obstetrics and Gynecology, 1993To examine the incidence and significance of complications related to percutaneous fetal blood sampling, we reviewed all the articles published in the English literature on this procedure. Risks of complications and adverse outcomes depend mainly on the gestational age at the time of the procedure, the operator's experience, and the indication for the ...

Fetal blood sampling is now performed in many centres through different approaches (fetoscopy, placentacentesis, cardiac puncture, umbilical cord needling, intrahepatic vein puncture) for prenatal diagnosis of congenital defects, management of intrauterine growth retardation and fetal therapy.

The Lancet, 1975
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.

American Journal of Obstetrics and Gynecology, 2013
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 ...

Obstetrics and Gynecology Clinics of North America, 1993
Fetal blood sampling is accepted and widely practiced by experienced perinatologists. Its facile and safe access to the fetal circulation has broadened the spectrum of congenital disorders diagnosed prenatally. Some fetal disease states can now be identified and treated earlier, directly, more quickly, and more effectively than before, resulting in ...

Clinics in Perinatology, 1974
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.

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 lymphocytes, trophoblasts, and nucleated red blood cells have each been separated from maternal blood by methods such as flow cytometry, magnetic cell sorting, and charge flow separation. The frequency of fetal cells among circulating maternal mononuclear cells remains to be ascertained.
