Intrapartum Fetal Hypoxia and Biochemical Markers
Obstetrical & Gynecological Survey, 1998Intrapartum 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

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 ...

The role of Doppler technology in the evaluation of fetal hypoxia
Early Human Development, 1992Failing intrauterine support to the fetus can lead to intrauterine growth retardation (IUGR) and hypoxia and it is associated with a high risk of perinatal morbidity and mortality. The main effects of moderate to severe hypoxia on the fetus are different degrees of blood flow redistribution and reduction of oxygen consumption to maintain oxygen ...

The Effect of Fetal Hypoxia and Acidosis on the Changes in Fetal Electroencephalogram During Labor
American Journal of Perinatology, 1988As artefact-free recordings of the fetal brain bioelectric potentials can only be obtained by specially designed electrodes, an electrode for taking electroencephalogram (EEG) and cardiotocogram (CTG), according to the principle of vacuum electrode developed by Rosen and Scibetta, has been designed. The polygraphic technique was used to examine a total

Dynamics of fetal circulatory responses to hypoxia and asphyxia
European Journal of Obstetrics & Gynecology and Reproductive Biology, 1999This review will focus on the dynamic changes of the fetal circulation, the distribution of organ blood flow during normoxemia, and that during hypoxia and asphyxia caused by various experimental perturbations. Furthermore, the relation between oxygen delivery and tissue metabolism during oxygen lack as well as evidence to support a new concept will be

Effects of maternal hypoxia on fetal cardiovascular hemodynamics
American Journal of Obstetrics and Gynecology, 1970Abstract The effects of hypoxia on fetal cardiovascular hemodynamics were monitored in 24 near-term pregnant ewes and their fetal lambs. In one group of animals, effects of hypoxia on fetal effective cardiac output (ductus + aortic flows) were studied; in another group, the effects of hypoxia on pulmonary hemodynamics were investigated. Mild or early

The effects of intrapartum hypoxia on the fetal QT interval
BJOG: An International Journal of Obstetrics & Gynaecology, 2004Background The morphology of the fetal ECG complex provides information on the fetal condition during labour, such as the ST segment and T‐wave configuration. We hypothesised that the intrapartum fetal QT interval may provide additional information on the condition of the fetus, as it is known that the QT interval reacts to situations of stress and ...

Cerebral Palsy and Fetal Hypoxia
1993Little, in 18621, stressed the association of abnormal parturition, difficult labor, premature labor, and asphyxia with cerebral palsy.

The pattern of breathing of fetal sheep in graded hypoxia
European Journal of Obstetrics & Gynecology and Reproductive Biology, 1989We examined the effects on fetal breathing movements (FBM) and electrocortical activity (ECoG) of maintaining fetal arterial PO2 (PaO2) at 16.9 +/- 1.9 mmHg for 20 min in unanaesthetized, chronically instrumented fetal sheep in utero at 122-132 days gestation. In 82% of trials, a pattern of regular FBM occurred characterised by its large (35 +/- 7 mmHg)

Effect of Hypoxia on Fetal Rabbit Gastrointestinal Motility
Journal of Surgical Research, 2001During fetal hypoxic stress, blood flow is shunted from nonvital to life-preserving organs, including the heart and brain. Reduced oxygen to the small intestine (SI) induces mucosal injury and may contribute to neonatal necrotizing enterocolitis (NEC).
