81. Automated analysis of fetal cardiac function using color tissue Doppler imaging. (PubMed)

Automated analysis of fetal cardiac function using color tissue Doppler imaging. To evaluate the feasibility of automated analysis of fetal myocardial velocity recordings obtained by color tissue Doppler imaging (cTDI).This was a prospective cross-sectional observational study of 107 singleton pregnancies ≥ 41 weeks of gestation. Myocardial velocity recordings were obtained by cTDI in a long-axis four-chamber view of the fetal heart. Regions of interest were placed in the septum and the right (...) (RV) and left (LV) ventricular walls at the level of the atrioventricular plane. Peak myocardial velocities and mechanical cardiac time intervals were measured both manually and by an automated algorithm and agreement between the two methods was evaluated.In total, 321 myocardial velocity traces were analyzed using each method. It was possible to analyze all velocity traces obtained from the LV, RV and septal walls with the automated algorithm, and myocardial velocities and cardiac mechanical time

82. Electronic Fetal Monitoring With and Without Pattern Interpretation

rate tracing is recorded on paper or electronically and produces a pattern to allow physicians to visually identify fetuses that are at risk for hypoxia and/or acidemia. This practice allows for prompt intervention via intrauterine resuscitation and expedited delivery if deemed necessary. National and international guidelines published by the International Federation of Gynecology and Obstetrics and American College of Obstetrics and Gynecology describe how fetal heart rate patterns obtained (...) , then their patient information will be collected. Their labor will be managed as in Phase 1 except that EFM will be interpreted and managed as per ACOG/FIGO guidelines using paper on which fetal heart tracings will be recorded. All other aspects of their care will proceed as per standard at Ayder Referral Hospital. Patients who require EFM will be asked to provide basic health and demographic information, along with collection of information on labor and delivery course, post-partum outcome, and neonatal

86. Accuracy of intrapartum fetal blood gas analysis by scalp sampling: A retrospective cohort study. (Full text)

Accuracy of intrapartum fetal blood gas analysis by scalp sampling: A retrospective cohort study. Fetal blood gas analysis (FBGA) using scalp blood is commonly used to identify serious fetal distress. However, there is a lack of data regarding its accuracy and reliability. The aim of this study was to determine the positive predictive value (PPV) and negative predictive value (NPV) of FBGA for predicting postpartum acidosis in case of nonreassuring fetal heart rate tracings (NRFHRT (...) to determine the influence of cardiotocography variations and the time delay between FBGA and delivery on the accuracy of FBGA. We analyzed 343 deliveries with NRFHRT. In 32 (9%) of these cases, fetal acidosis was confirmed by a postpartum umbilical cord blood pH value ≤ 7.15. In 308/343 (90%) cases, FBGA identified NRFHRT as false positive (as confirmed by nonacidotic postpartum pH values) and thus avoided unnecessary interventions such as operative delivery. The overall test accuracy of FBGA was 91

was indeterminate according to an indefinite fetal heart rate tracing with regular decelerations. After emergent cesarean delivery, a ruptured vasa previa, traversing the fetal membrane, unsupported by either the umbilical cord or placental tissue, was clearly identified. Treatment decision-making is challenging in such patient with indefinite fetal heart rate pattern because limited data exist to guide management. Well-designed studies are needed to clarify the uncertainty about the effect of indefinite fetal (...) Indefinite Fetal Heart Rate Pattern in a Patient with Vasa Previa: A Situation Where Guideline Is Inapplicable Most fetal heart rate patterns can be interpreted accurately so that management decisions can be made correctly. How-ever, few fetal heart rate patterns are so ambiguous that the obstetricians cannot interpret them precisely. A 27-year-old woman at 38 weeks' gestation in her first pregnancy was admitted with heavy vaginal bleeding and decrease in fetal movements. Fetal status

88. Phase-rectified signal averaging for intrapartum electronic fetal heart rate monitoring is related to acidaemia at birth. (Full text)

Phase-rectified signal averaging for intrapartum electronic fetal heart rate monitoring is related to acidaemia at birth. Recent studies suggest that phase-rectified signal averaging (PRSA), measured in antepartum fetal heart rate (FHR) traces, may sensitively indicate fetal status; however, its value has not been assessed during labour. We determined whether PRSA relates to acidaemia in labour, and compare its performance to short-term variation (STV), a related computerised FHR

89. Evaluation of fetal wellbeing by antepartum fetal heart monitoring. (Full text)

Evaluation of fetal wellbeing by antepartum fetal heart monitoring. The value of antenatal fetal heart rate monitoring was assessed in 301 patients. Tracings from each patient were classified as "reactive" or "non-reactive." Perinatal mortality, fetal distress in labour, caesarean section for fetal distress, and the incidence of low Apgar scores were all significantly increased in the non-reactive group.

92. Fetal Awareness: Review of Research and Recommendations for Practice

for signalling noxious events to the central nervous system. Noxious stimuli are those that damage the tissues of the body or threaten to do so, such as surgical incision or physical trauma of the skin. In this context, we define pain as ‘the unpleasant sensory or emotional response to such tissue damage’ and trace the development of those responses through fetal development. We follow the path of the sig- nals produced by tissue damage at sensory detectors in the skin and other organs, through to sensory (...)

Intrapartum fetal scalp lactate sampling for fetal assessment in the presence of a non-reassuring fetal heart rate trace. Fetal blood sampling for lactate estimation may be considered following identification of an abnormal or non-reassuring fetal heart rate pattern. The smaller volume of blood required for this test, compared with the more traditional pH estimation, may improve sampling rates. The appropriate use of this practice mandates systematic review of its safety and clinical (...) effectiveness prior to widespread introduction.To evaluate the effectiveness and risks of fetal scalp lactate sampling in the assessment of fetal well-being during labour, compared with no testing or alternative testing.We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (November 2009).All published and unpublished randomised and quasi-randomised trials that compared fetal scalp lactate testing with no testing or alternative testing to evaluate fetal status in the presence of a non

95. Effect of magnesium sulfate on fetal heart rate patterns in the second stage of labor. (Full text)

Effect of magnesium sulfate on fetal heart rate patterns in the second stage of labor. To estimate the effect of maternal exposure to magnesium sulfate on fetal heart rate characteristics during active labor.Within a 4-year retrospective cohort study of consecutive term deliveries reaching the second stage of labor, we compared women exposed to magnesium for severe preeclampsia to all women not exposed. Primary outcome was the electronic fetal monitoring tracing in the 30 minutes preceding (...) delivery. Secondary outcomes were fetal acidemia and nursery disposition. Attributable risk estimates and multivariable logistic regression were used to estimate the association between magnesium exposure and fetal heart rate characteristics. Unadjusted risk estimates for the association between fetal heart rate characteristics and neonatal outcomes were generated stratified by group.Of 5,387 women, 248 (4.6%) were exposed to magnesium. Magnesium exposure was associated with lower fetal heart rate

97. Genetic Fate Mapping Defines the Vascular Potential of Endocardial Cells in the Adult Heart. (Full text)

Genetic Fate Mapping Defines the Vascular Potential of Endocardial Cells in the Adult Heart. Endocardium is the major source of coronary endothelial cells (ECs) in the fetal and neonatal hearts. It remains unclear whether endocardium in the adult stage is also the main origin of neovascularization after cardiac injury.To define the vascular potential of adult endocardium in homeostasis and after cardiac injuries by fate-mapping studies.We generate an inducible adult endocardial Cre line (Npr3 (...) [natriuretic peptide receptor C]-CreER) and show that Npr3-CreER efficiently and specifically labels endocardial cells but not coronary blood vessels in the adult heart. The adult endocardial cells do not contribute to any vascular ECs during cardiac homeostasis. To examine the formation of blood vessels from endocardium after injury, we generate 4 cardiac injury models with Npr3-CreER mice: myocardial infarction, myocardial ischemia-reperfusion, cryoinjury, and transverse aortic constriction.
