OBJECTIVE To investigate the effect of maternal hyperoxygenation on fetal oxygenation and fetal heart rate decelerations during labor, using a simulation model. DESIGN Use of a mathematical model that simulates feto-maternal hemodynamics and oxygenation, designed in Matlab R2012a. SETTING Clinical and engineering departments in the Netherlands. METHODS We simulated variable and late fetal...

The electric fetal heart activity was firstly recorded as tiny deflections on maternal limb lead electrocardifogram (ECG) by Cremer [1], direct lead fetal ECG with needle electrode by Caldeyro-Barcia et al. [2] and with scalp lead clip electrode by Hon [3]. Indirect maternal abdominal lead fetal ECG (fECG) was recorded by Maeda and Nakano [4] and others. Intrapartum fetal heart rate (FHR) was m...

The enzyme level profiles of some regulatory enzymes and the isozyme patterns of some marker enzymes in bovine adult specialized, adult ordinary and fetal ordinary heart muscles were examined in order to biochemically characterize specialized heart muscle. The activities of hexokinase, phosphofructokinase and glucose-6-phosphate dehydrogenase in adult specialized heart muscle were significantly...

BACKGROUND The fetal anomaly ultrasound only detects 65 to 81 % of the patients with congenital heart disease, making it the most common structural fetal anomaly of which a significant part is missed during prenatal life. Therefore, we need a reliable non-invasive diagnostic method which improves the predictive value for congenital heart diseases early in pregnancy. Fetal electrocardiography co...

The purpose of the study was to compare the accuracy of a noninvasive fetal heart rate monitor with that of ultrasound, using a fetal scalp electrode as the gold standard, in laboring women of varying body habitus, throughout labor and delivery. Laboring women requiring fetal scalp electrode were monitored simultaneously with the investigational device (noninvasive fetal ECG), ultrasound, and f...

conclusions: normothermia and hemodynamic stability are the most important factors which help to reduce fetal loss during open heart surgery in pregnancy. the fetus has an auto-regulation which comes into play when the mother is experiencing shock. objectives: the aim of this study was to report our experience with urgent cardiopulmonary bypass carried out in early pregnancy and to analyze fact...
