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 ...

Les auteurs indiquent la technique d'etude de l'irrigation cerebrale du fœtus par examen Doppler ainsi que les differents parametres modifiant l'enregistrement: mouvements respiratoires du fœtus, son etat d'activite, l'activite cardiaque et les stimulations acoustiques.

Ultrasound-guided fetal blood transfusions allow precise assessment and rational treatment of the anemic fetus. Outcome improves for all such fetuses, but particularly in the hydropic, moribund group.

Fetal blood volume restoration following rapid fetal hemorrhage
American Journal of Physiology-Heart and Circulatory Physiology, 1990In a previous study, we found that ovine fetal blood volume returned to normal in 3 h after a slow hemorrhage of 31% over 2 h; volume was slightly elevated at 24-25 h. In the present study, we explored the time required for blood volume restoration in late gestation fetal sheep following a rapid hemorrhage over 10 min.

Fetal blood flow measurements during fetal cardiac arrythmia
Early Human Development, 19843 cases of fetal complete heart block, 1 case of fetal bradycardia and 2 cases of fetal supraventricular tachycardia were studied. Using an ultrasonic technique combining real-time ultrasound with a pulsed Doppler system, blood flow measurements at the lower thoracic level of the fetal descending aorta were taken.

Abstract There occur occasional cases of asphyxia neonatorum in which the obstetrician, for want of other explanation, incriminates the anesthesia given at the time of delivery. The studies of Leake, 1 of Ronzoni, 2 of Raginsky and Bourne, 3 and of others, indicate that in adults the common inhalation anesthetics produce decided changes in the acid-

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.

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.
