42. Human factors affecting the interpretation of fetal heart rate tracings: an update. Full Text available with Trip Pro

Human factors affecting the interpretation of fetal heart rate tracings: an update. Human factors can have an important impact on cardiotocography (CTG) interpretation and management decisions, and therefore may directly affect obstetrical outcomes.It has been well demonstrated that there is wide observer disagreement over CTG interpretation, particularly in the evaluation of variability, decelerations, and overall tracing classification. The reasons behind this are still incompletely

fetuses with confirmed congenital heart defects. A control group was selected by matching each fetus with a congenital heart defect with two fetuses in the control group with similar crown-rump length (± 5 mm) and date of study (± 2 months). Cardiac axis was measured on the four-chamber view as the angle between the line that traces the long axis of the heart and the line that bisects the thorax in an anteroposterior direction.In the control group, mean cardiac axis was 44.5 ± 7.4°.

45. Effect of Oxygen vs Room Air on Intrauterine Fetal Resuscitation: A Randomized Noninferiority Clinical Trial Full Text available with Trip Pro

Effect of Oxygen vs Room Air on Intrauterine Fetal Resuscitation: A Randomized Noninferiority Clinical Trial Two-thirds of women in labor receive supplemental oxygen to reverse perceived fetal hypoxemia and prevent acidemia. Oxygen is routinely administered for category II fetal heart tracings, a class of fetal tracing used to designate intermediate risk for acidemia. This liberal use of oxygen may not be beneficial, particularly because neonatal hyperoxygenation is harmful.To test (...) the hypothesis that room air is noninferior to oxygen in improving fetal metabolic status among patients with category II fetal heart tracings.This was a randomized, unblinded noninferiority clinical trial conducted between June 2016 and July 2017 in the labor and delivery ward of a single tertiary care center. Women with singleton pregnancies at 37 weeks' gestational age or more who were admitted for delivery were eligible. Of those who met inclusion criteria, the patients who developed category II tracings

Patients were enrolled at labor admission and randomized in blocks based on body mass index to fetal electrocardiography or standard external monitoring. Two reviewers, blinded to study allocation, reviewed each fetal heart rate tracing. The primary outcome was the percentage of interpretable minutes of fetal heart rate tracing. An interpretable minute was defined as >25% fetal heart rate data present and no more than 25 (...) % continuous missing fetal heart rate data or artifact present. Secondary outcomes included the percentage of interpretable minutes of fetal heart rate tracing obtained while on study device only, the number of device adjustments required intrapartum, clinical outcomes, and patient/provider device satisfaction. We determined that 100 patients per arm (200 total) would be needed to detect a 5% difference in interpretability with 95% power.A total of 218 women were randomized, 108 to fetal

with Fontan circulation, and this population is expected to double in the next 20 years. In the absence of a subpulmonary ventricle, Fontan circulation is characterized by chronically elevated systemic venous pressures and decreased cardiac output. The addition of this acquired abnormal circulation to innate abnormalities associated with single-ventricle congenital heart disease exposes these patients to a variety of complications. Circulatory failure, ventricular dysfunction, atrioventricular valve (...) are just being recognized. The hallmark of the Fontan circulation is a sustained, abnormally elevated central venous pressure combined with decreased cardiac output, especially during periods of increased demands, resulting in a cascade of physiological consequences. Clinical hazards faced by patients include progressive fatigue, heart failure, arrhythmias, and end-organ complications such as liver disease, in addition to anxiety and concern about their condition and future.

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

53. Antenatal foetal heart monitoring. (Abstract)

Antenatal foetal heart monitoring. Antenatal foetal heart rate assessment was introduced into clinical medicine before clear evidence of any benefits had been reported. Ad hoc definitions were used to define normal and abnormal recordings resulting in a high false-positive rate for foetal compromise. The understanding of the foetal states resulted in an improved physiologically based assessment of the antenatal tracings and allowed their classification as (i) reactive - 2 accelerations in 10 (...)  min within a recording period of 120 min, (ii) unreactive - no accelerations seen in 120 min of tracing and (iii) decelerative - the presence of repetitive decelerations on an otherwise unreactive trace. This classification reduces the high rate of false-positive traces associated with recording times of less than 40 min. Traces performed on pregnancies before 32 weeks predict clinical outcome, but need to be interpreted in light of the fact the many foetuses will not show a mature reactive

Absence of accelerations during labor is of little value in interpretation of fetal heart rate patterns. The aim of this study was to investigate the correlation between increasing time since fetal heart rate (FHR) accelerations, positive (no acceleration) stimulation tests and fetal acidemia.Observational study of FHR recordings from 1070 laboring women with indication for fetal scalp blood sampling (FBS). FHR traces were scrutinized regarding acceleration at FBS and duration since most recent (...) acceleration and increased lactate concentration. The majority of fetuses are not acidemic even when the FHR trace is pathological and stimulation tests are only helpful when accelerations are provoked.© 2016 Nordic Federation of Societies of Obstetrics and Gynecology.

fetal heart rate tracings from the terminal 30 minutes before delivery. A website was created to view these tracings with the use of the standard Hon-Quilligan method and adjusted the same tracings to the 1 cm/min monitoring speed for the Caldeyro-Barcia method. We invited 2-4 caregivers to participate: maternal-fetal medicine experts, practicing maternal-fetal medicine specialists, maternal-fetal medicine fellows, obstetrics nurses, and certified nurse midwives. After completing an introductory (...) tutorial and quiz, they were asked to interpret the fetal heart rate tracings (the order was scrambled) to manage and predict maternal and neonatal outcomes using both methods. Their results were compared with those of our expert, Edward Quilligan, and were compared among groups.

gestational age at the time of IUFD was 35.5 weeks. Three controls were matched to each case for a total of 24 subjects, and 87 FHR tracings were included for analysis. The median gestational age at the first fetal heart rate tracing was similar between groups (median [1st-3rd quartiles] weeks: IUFD cases: 34.7 (34.4-36.2); controls: 35.3 (34.4-36.1); p=.94). The median complexity of the cases' tracings was significantly less than the controls' (12.44 [8.9-16.77] vs. 17.82 [15.21-22.17]; p<.0001 (...) Complexity analysis of fetal heart rate preceding intrauterine demise Visual non-stress test interpretation lacks the optimal specificity and observer-agreement of an ideal screening tool for intrauterine fetal demise (IUFD) syndrome prevention. Computational methods based on traditional heart rate variability have also been of limited value. Complexity analysis probes properties of the dynamics of physiologic signals that are otherwise not accessible and, therefore, might be useful

The Influence of a Crosshair Visual Aid on Observer Detection of Simulated Fetal Heart Rate Signals Objective To determine whether a visual aid overlaid on fetal heart rate (FHR) tracings increases detection of critical signals relative to images with no visual aid. Study Design In an experimental study, 21 undergraduate students viewed 240 images of simulated FHR tracings twice, once with the visual aids and once without aids. Performance was examined for images containing three different (...) variability condition. Conclusion The results of the study provide evidence that the presence of a visual aid was useful in helping novices identify FHR signals in simulated maternal-fetal heart rate images. Further, the visual aid was most useful for conditions in which the signal is most difficult to detect (when FHR variability is highest).
