61. Cardiotocography alone vs. cardiotocography with ST segment analysis for intrapartum fetal monitoring in women with late-term pregnancy. A randomized controlled trial. (Abstract)

heart rate alterations during labor, i.e. groups of women who share late-term pregnancy as a risk factor.This randomized clinical trial recruited women whose pregnancy had lasted more than 290 days. The participants were randomly assigned to continuous fetal cardiotocographic monitoring alone (CTG group) or with fetal ECG ST-segment analysis (ECG-F group). In the CTG group fetal heart rate was interpreted according to guidelines from the National Institute of Child Health and Human Development (...) , whereas in the ECG-F group the tracings were interpreted according the original International Federation of Gynecology and Obstetrics (FIGO) guidelines. The primary outcome measure was neonatal outcome, evaluated as arterial blood pH in neonates after abdominal or vaginal operative delivery indicated because of nonreassuring fetal status.A total of 237 women were randomized, of whom 200 were included in the final analysis (100 in each group). The rate of cesarean delivery was the same in both groups

62. Fetal echocardiographic assessment of the cardiovascular impact of prolonged support in the EXTrauterine Environment for Neonatal Development (EXTEND) system. Full Text available with Trip Pro

studied fetal sheep supported for a minimum of 3 weeks on EXTEND. Hemodynamic parameters of heart rate, mean arterial pressure, Doppler echocardiography derived cardiac output, pulsatility indices of middle cerebral artery, umbilical artery, and ductus venosus, and cardiac function as gauged by speckle tracking derived global longitudinal strain and strain rate of right and left ventricles, were all measured weekly and compared.Of 10 fetal sheep, 7 survived for 3 weeks and were studied. Median (...) gestational age at cannulation was 107 days (range 95-109). Parameters of heart rate, blood pressure, the quantities and relative ratios of right and left cardiac output all remained stable within the anticipated physiological range throughout. Vascular tracings and pulsatility indices appeared similar to normal as seen in the natural in-utero state, with middle cerebral pulsatility indices higher than umbilical arterial. Umbilical arterial tracings maintained abundant diastolic flow despite absence

63. Evolution of the Fetal Atrioventricular Interval from 6 to 40 Weeks of Gestation. (Abstract)

the first trimester to 40 weeks gestational age, and to explore functional and electrophysiological events that potentially impact its evolution. We prospectively examined healthy pregnancies by fetal echocardiography from 6 to 40 weeks' gestational age. The atrioventricular interval, heart rate, isovolumic contraction time, and A-wave duration were measured from simultaneous ventricular inflow-outflow Doppler tracings. Regression analysis was used to examine relations with gestational age, and linear (...) Evolution of the Fetal Atrioventricular Interval from 6 to 40 Weeks of Gestation. Doppler-based methods of estimating the atrioventricular interval are commonly used as a surrogate for the electrical PR in fetuses at risk of conduction abnormalities; however, to date, normal values for the fetal atrioventricular interval and an understanding of the evolution of its components in the late first trimester are lacking. We sought to investigate changes in the fetal atrioventricular interval from

66. Feasibility of Non-invasive Fetal Electrocardiographic Interval Measurement in the Outpatient Clinical Setting. (Abstract)

Feasibility of Non-invasive Fetal Electrocardiographic Interval Measurement in the Outpatient Clinical Setting. Non-invasive fetal electrocardiography (ECG) is a promising method for evaluating fetal cardiac electrical activity. Despite advances in fetal ECG technology, its ability to provide reliable, interpretable results in a typical outpatient fetal cardiology setting remains unclear. We sought to determine the feasibility of measuring standard ECG intervals in an outpatient fetal (...) 25-31 and 32-37 weeks. Of the six fetuses with abnormal rhythms on fetal echocardiogram, fetal ECG tracing was interpretable in five and matched the rhythm noted on fetal echocardiogram. Abdominal fetal ECG acquisition is feasible for arrhythmia detection and ECG interval calculation in a routine clinical setting.

76. Comparison of Intrathecal Versus Epidural Fentanyl on Fetal Bradycardia in Labor Combined Spinal Epidural Analgesia

any differences in risk exist between fentanyl and bupivacaine when used as a part of the CSE procedure. Some authors have reported cases of parturients who developed uterine hyperactivity and fetal bradycardia after subarachnoid administration of fentanyl during labor. (D'Angelo & Eisenach, 1997) (Friedlander JD, 1997). It has been suggested that uterine hypertonus, leading to non-reassuring fetal heart rate tracings, might be an etiologic factor in these situations. (Landau, 2002). We propose (...) preservative-free 0.25% bupivacaine and epidural fentanyl 100 mcg. After the procedure, we will monitor the fetal heart rate and tocometry tracings for 20 min. Thereafter, an epidural infusion with a solution containing 0.125% bupivacaine and 2mcg/mL of fentanyl will be started. We will record demographic variables (age, and BMI), obstetric variables (parity, gestational age, cervical dilation, oxytocin infusion) and anesthetic variables (level of insertion of epidural catheter).

Distention of the Immature Left Ventricle Triggers Development of Endocardial Fibroelastosis: An Animal Model of Endocardial Fibroelastosis Introducing Morphopathological Features of Evolving Fetal Hypoplastic Left Heart Syndrome Endocardial fibroelastosis (EFE), characterized by a diffuse endocardial thickening through collagen and elastin fibers, develops in the human fetal heart restricting growth of the left ventricle (LV). Recent advances in fetal imaging indicate that EFE development (...) is directly associated with a distended, poorly contractile LV in evolving hypoplastic left heart syndrome (HLHS). In this study, we developed an animal model of EFE by introducing this human fetal LV morphopathology to an immature rat heart.A neonatal donor heart, in which aortic regurgitation (AR) was created, was heterotopically transplanted into a recipient adult rat. AR successfully induced the LV morphology of evolving HLHS in the transplanted donor hearts, which resulted in the development
