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.

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.

Transfusion, 2007
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 Sampling and Fetal Thrombocytopenia
Fetal Diagnosis and Therapy, 2009The 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 ...

Journal of Nurse-Midwifery, 1993
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.

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.

Cytogenetic Micromethod on Fetal Blood
Gynecologic Investigation, 2010A 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.

Cytogenetic Studies in Fetal Blood
Fetal Diagnosis and Therapy, 1998In order to assess the effectiveness and reliability of cytogenetic diagnosis provided by fetal blood, we report the first 186 cases of fetal blood sampling performed for rapid karyotype between 19–37 weeks of pregnancy in our Prenatal Diagnosis Unit.

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.
