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 ...

Clinical Genetics, 2001
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.

Progesterone metabolism in fetal blood
Steroids, 1968Abstract Fetal blood from sheep and cattle rapidly metabolized 4-14C-progesterone in vitro , to produce as the major product 4-14C-20α-hydroxy-pregn-4-en-3-one. The reaction was reversible, although at normal blood pH values and in the presence of actively metabolizing red blood cells the formation of the C-2O reduction product was favoured ...

Complications of fetal blood sampling
American Journal of Obstetrics and Gynecology, 1970Abstract Fetal blood sampling has been employed in the diagnosis of fetal distress at the Columbia-Presbyterian Medical Center since November, 1965. A total of 1,200 samples have been obtained from 678 infants with 6 neonatal complications. Scalp abscesses developed in 3 infants and 3 sustained substantial hemorrhages from scalp incisions.

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 ...

The Lancet, 1974
Abstract A fetal blood-sample, adequate for the study of haemoglobin synthesis, can be obtained by aspiration of the anterior placenta. In a preliminary trial, the procedure was successful in 58% (eleven) of the nineteen cases and seemed to be safe.

The oxygen status of fetal blood
Acta Anaesthesiologica Scandinavica, 1995Objective: To estimate the acid‐base and oxygen status of fetal blood and compare with maternal placental venous blood.Data sources and calculations: We selected pH and blood gas data from the literature pertaining to umbilical vein and artery blood obtained by cordocentesis and estimated values for the 30th and 40th gestational week.Average values for

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 ...

Cytogenetic Micromethod on Fetal Blood
Gynecologic and Obstetric Investigation, 1973A lymphocyte culture method was developed that allow the use of as little as 0.01 ml of fetal blood. The yield of metaphase plates for the assessment of cytogenetic abnormalities was good. A safe way to aspirate fetal blood early in pregnancy is required, so the present method will be useful.
