Causes and Mechanisms of Intrauterine Hypoxia and Its Impact …
Hypoxia slows fetal growth, and growth restriction is now considered a risk factor of premature arterial hypertension and cardiovascular disease, probably secondary to endothelial dysfunction. Further investigations are needed to explore preventative strategies such as the early use of antioxidants and selective vasodilators to limit the ...
Intrauterine hypoxia - Wikipedia
Intrauterine hypoxia (also known as fetal hypoxia) occurs when the fetus is deprived of an adequate supply of oxygen. It may be due to a variety of reasons such as prolapse or occlusion of the umbilical cord, placental infarction, maternal diabetes (prepregnancy or gestational diabetes) [1] and maternal smoking.
Current paradigms and new perspectives on fetal hypoxia: implications ...
The most common forms of fetal hypoxia are most likely hypoxic hypoxia, secondary to exposure to altitude, and asphyxic hypoxia, perhaps most common during labor contractions. These three types of hypoxia can occur either transiently or chronically.
Perinatal Hypoxemia and Oxygen Sensing - PMC - PubMed …
Fetal intermittent hypoxia, also called gestational intermittent hypoxia, decreases FBM hourly incidence but increases FBM amplitude and inspiratory efforts during the hypoxic episodes. Postnatally, fetal intermittent hypoxia reduces the HVR and capacity for gasping and autoresuscitation and an increase in eupneic breathing.
Types of intrapartum hypoxia in the newborn at term with …
2022年8月25日 · Our objective was to classify the type of hypoxia in the case of metabolic acidemia and to describe the order of appearance of fetal heart rate abnormalities in cases of gradually evolving hypoxia. 132 neonates born between 2018 and 2020 with acidemia were included. We excluded preterm birth, fetuses with congenital anomaly and twin pregnancies.
Intrauterine hypoxia: clinical consequences and therapeutic …
2015年4月30日 · We can classify intrauterine hypoxia into two categories: 1) pre-placental hypoxia, where the mother and fetus are both hypoxic (ie, high altitude exposure, cyanotic maternal heart diseases); and 2) uteroplacental hypoxia, where the mother’s oxygenation is normal but the uteroplacental circulation is impaired.
Detection and response to acute systemic hypoxia - BJA ... - BJA …
In this article, we examine how mammals detect hypoxic states and then explore in detail the respiratory, cardiovascular, metabolic and cerebrovascular responses in the adult. We will then consider how the fetus withstands such insults and consider the transition in the response to hypoxia from fetal to postnatal life.
Optimizing the management of acute, prolonged decelerations and fetal …
Therefore, any acute fetal hypoxia, which manifests as a prolonged deceleration on the fetal heart rate tracing, should be considered an intrapartum emergency requiring an immediate intervention to optimize perinatal outcome.
Acute Fetal Hypoxia/Acidosis - SpringerLink
2016年9月1日 · Fetal hypoxia/acidosis may be caused by a number of acute maternal circulatory and respiratory disorders, including severe asthma, haemorrhagic shock, and cardiorespiratory arrest. During labour, however, the most common causes are pulmonary thromboembolism and amniotic fluid embolism.
FIGO consensus guidelines on intrapartum fetal monitoring: …
2015年9月30日 · While avoiding adverse fetal outcome related to hypoxia/acidosis is the main objective of intrapartum fetal monitoring, it is equally important that it does not result in unnecessary obstetric intervention, as some of these procedures, such as instrumental vaginal delivery and cesarean delivery, are associated with increased maternal and fetal ...
