Intrapartum Cardiotocography and Fetal Pulse Oximetry in Assessing Fetal Hypoxia

Obstetrical & Gynecological Survey, 2002
AbstractObjectives: A retrospective analysis of short‐term 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, 1990
Fifty-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, 1991
The 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, 1997
Vascular 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, 2010
Meconium 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, 1987
Cardiac 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.

Adrenomedullin expression during hypoxia in fetal sheep

Acta Physiologica Scandinavica, 2005
AbstractAim:  We asked how adrenomedullin (AM), a vasodilator peptide, was distributed in fetal sheep organs and whether expression of AM would be upregulated in response to moderate acute fetal hypoxia in vivo.Methods:  In four sheep at day 126–130 of gestation, nitrogen was added to the inspired air by tracheal infusion to reduce fetal arterial ...

Placental Immaturity, Endocardial Fibroelastosis and Fetal Hypoxia

Fetal Diagnosis and Therapy, 2009
We describe a term newborn who, after a normal gestational course, presented at birth with absent cardiac activity and no spontaneous breathing. Death occurred within 30 h. Autopsy revealed placental villous immaturity, multiple acute hypoxic lesions, but also chronic hypoxic lesions like endocardial fibroelastosis.

Intrapartum Fetal Hypoxia and Biochemical Markers

Obstetrical & Gynecological Survey, 1998
Intrapartum fetal hypoxia is a rare event, although fetal intrapartum surveillance is discussed as a subject of major importance. This is mainly because of consequences of fetal hypoxia that may lead to cerebral palsy. A fetus suffering from hypoxia initially compensates by producing energy through anaerobic metabolism. At some stage, the fetus becomes

Maternal smoking causes fetal hypoxia: Experimental evidence

American Journal of Obstetrics and Gynecology, 1982
Cigarette smoking during pregnancy has been related to poor perinatal outcome. To investigate the changes in maternal and fetal arterial blood gases associated with smoking, five chronically catheterized pregnant rhesus monkeys were exposed to standard cigarette smoking (N = 5) and nicotine-free herbal cigarette smoke (N = 3).
