Fetal metabolic responses to hypoxia
Reproduction, Fertility and Development, 1995It has been known for may years that hypoxaemia in the fetus induces a number of biophysical, cardiovascular, endocrine and metabolic responses by the fetus, some of which are not sustained if the period of hypoxaemia is extended. For instance, fetal breathing and body movements and the circulating concentrations of many of the stress-related hormones ...

Hypoxia Disturbs Fetal Hemodynamics and Growth
Endothelium, 2007Low-birth-weight babies have an increased risk of cardiovascular disease (CVD) in later life. The authors hypothesize that fetal hypoxia alters the structure and function of the developing cardiovascular system resulting in CVD. They investigated the effects of chronic hypoxia on cardiac performance, hemodynamic control, and growth during the second ...

Fetal blood volume responses to acute fetal hypoxia
American Journal of Obstetrics and Gynecology, 1986The purpose of this study was to explore the effects of acute hypoxia on the volume of blood circulating in the fetus. The oxygen content of air inspired by chronically catheterized, near-term pregnant sheep was reduced and supplemented with carbon dioxide in an attempt to maintain fetal carbon dioxide tension constant.

Moderate Hypoxia Exposure and Fetal Development
Archives of Environmental Health: An International Journal, 1975Exposure of rabbits to 15.5% oxygen during pregnancy resulted in a 17% decrease of birth weight and a neonatal mortality of 19% as opposed to 1% in the control groups, just corresponding to the effects obtained previously by moderate exposure of pregnant rabbits to carbon monoxide. Since additive effects of hypoxia exposure and carbon monoxide exposure

Intrapartum Cardiotocography and Fetal Pulse Oximetry in Assessing Fetal Hypoxia
Obstetrical & Gynecological Survey, 2002AbstractObjectives: A retrospective analysis of shortâterm variability (STV), a cardiotocography (CTG) parameter, in relation to fetal blood saturation values (FSpO2) obtained by fetal pulse oximetry. Methods: The study included 26 healthy pregnant women monitored continuously during delivery with both cardiotocography and fetal pulse oximetry. Results:

Is fetal insulin secretion affected by fetal hypoxia?
Early Human Development, 1990Fifty-five pregnant Rhesus isoimmunized women were subjected to fetal blood sampling or fetal blood transfusion on 135 occasions. Glucose and C-peptide concentrations were measured in fetal blood, in addition to the routine investigations for complete blood count, blood gases and lactate concentration, in order to investigate whether fetal insulin ...

Relationship Between Fetal Hypoxia and Endothelin-1 in Fetal Circulation
Journal of Cardiovascular Pharmacology, 1991The role of endothelin-1 (ET-1), a potent vasoconstrictor peptide secreted by endothelial cells, in fetal circulation was investigated in relation to fetal hypoxia. Umbilical venous blood was obtained from 23 subjects who delivered between 36 and 41 weeks of gestation.

Fetal arterial Doppler-IUGR and hypoxia
European Journal of Obstetrics & Gynecology and Reproductive Biology, 1997Vascular resistances of various fetal areas are assessed by Doppler ultrasound. The PI, RI and S/D indices are measured on the cerebral, renal, aortic and umbilical Doppler spectrum. Ratios of these indices based on the comparison of the cerebral (Rc) and the umbilical (Rp) resistances, or carotid (Rcc) and umbilical resistances, or cerebral (Rc) and ...

[Meconiophages and fetal hypoxia].
Akusherstvo i ginekologiia, 2010Meconium may normally be passed by term fetuses during labour. Common after 40 weeks and not a sign of fetal distress Before 40 weeks can implicate fetal distress If occurring in preterm fetuses or if present prior to labour, it may be considered a possible indication of fetal distress.

Severe fetal supraventricular bradyarrhythmia without fetal hypoxia.
Obstetrics and gynecology, 1987Cardiac anatomy and rhythm were evaluated in a fetus at 39 weeks' gestation in a pregnant woman referred because of severe fetal bradycardia with a persistent fetal heart rate of 50-60 beats per minute. M-mode echocardiograms revealed supraventricular bradyarrhythmia. Umbilical cord blood analysis did not, however, reveal fetal hypoxia.
