Saltatory Pattern of Fetal Heart Rate during Labor Is a Sign of Fetal Hypoxia
Neonatology, 2019Background: While late decelerations and major bradycardia episodes in intrapartum cardiotocography (CTG) recordings are known to correlate with fetal distress,little is known of the importance of the saltatory pattern.

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

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 ...

Iatrogenic diseases are defined as diseases due to medical interference. They must be as old as medicine itself. Their particular and almost tragic pecularity is given by the fact that measures taken to improve the health of human beings finally exert an opposite effect and are the cause of a new disease.

Doppler velocimetry in the evaluation of fetal hypoxia
Journal of Perinatal Medicine, 2001Knowledge of fetal hemodynamic physiology has developed enormously during the last two decades due to Doppler ultrasound. Some of this knowledge has been utilized for routine surveillance of high-risk pregnancies. The prediction of fetal hypoxia before the development of life lasting sequel is of major importance, especially in the very premature case ...

Intrapartum Cardiotocography and Fetal Pulse Oximetry in Assessing Fetal Hypoxia
Obstetrical & Gynecological Survey, 2002AbstractObjectives: 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:

Cumulative changes in the fetal electrocardiogram and biochemical indices of fetal hypoxia
European Journal of Obstetrics & Gynecology and Reproductive Biology, 1994Previous studies have shown that the relationship between P-R interval of the fetal electrocardiogram (FECG) and the fetal heart rate (FHR) varies according to the acid-base status of the fetus. In the normal fetus there is a negative correlation between these two parameters. However, as acidosis develops, the relationship becomes positive. In order to

Adrenomedullin expression during hypoxia in fetal sheep
Acta Physiologica Scandinavica, 2005AbstractAim: 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 ...

Development and Mechanisms of Fetal Hypoxia in Severe Fetal Growth Restriction
Placenta, 2007Severe fetal growth restriction (FGR) is often associated with hypoxia. We studied FGR hypoxia in an experimental model which is produced by exposing pregnant ewes to a hyperthermic environment. The study utilized simultaneous measurements of several relevant factors, e.g., uterine and umbilical blood flows and O(2) uptakes.

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.
