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

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.

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.

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.

Annual Review of Medicine, 1989
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.

Transferrin Microheterogeneity in Fetal Blood
Neonatology, 2004<i>Objectives:</i> To investigate the distribution of microheterogeneous subfractions of transferrin in fetal blood and the influence of highly sialylated transferrins on fetal growth. <i>Study Method:</i> Serum transferrin concentrations were determined by a standard turbidimetric assay.

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.

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 ...

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
