BACKGROUND: Complete atrioventricular block in fetuses is known to be mostly associated with autoimmune disease and can be irreversible if no steroids treatment is provided. Conventional methods used in clinical practice for diagnosing fetal arrhythmia are limited since they do not reflect the primary electrophysiological conduction processes that take place in the myocardium. The non-invasive fetal electrocardiogram has the potential to better support fetal arrhythmias diagnosis through the continuous analysis of the beat to beat variation of the fetal heart rate and morphological analysis of the PQRST complex...

REVIEW
Lucy M Safi, Sarah V Tsiaras
Valvular heart disease in women of childbearing age poses an increased risk of adverse maternal and fetal outcomes, and management in pregnancy can be challenging. Ideally, patients with suspected valvular disease should have preconception counseling by a multidisciplinary team including cardiologists with expertise in pregnancy and a maternal-fetal medicine specialist. Preconception planning should include a cardiac assessment of maternal risk, determination of frequency of surveillance, and a cardiovascular management plan during delivery...

The developing fetus has some unique physiological properties that differ from properties in extra-uterine life. The fetus exists in a hypoxemic condition as a result of the presence of the placenta, which serves as a limiting interface between maternal and fetal circulation. In addition, the fetus is prone to be exposed to uterine contractions, which place it under a further hypoxic burden. Thus, the fetal response to hypoxic insults is important. There has been marked progression in the understanding of fetal physiology since the introduction of the 'chronic preparation model'...

Infective endocarditis (IE) during pregnancy is a rare but serious condition. Cardiopulmonary bypass during pregnancy has a high rate of fetal morbidity and mortality. We here report the case of a 22-year-old pregnant woman with confirmed IE. Multiple large cardiac valve vegetations, severe aortic valve regurgitation, and hemodynamic compromise were observed. With full implementation of fetal monitoring and protection strategies, open heart surgery was performed at 31.4 weeks' gestation to aid survival, followed by an elective cesarean delivery at 34...

BACKGROUND: Epidural administration of neostigmine appears to be safe in the obstetric population. Recently, few studies have concluded 10 μg sufentanil to be an effective adjuvant with epidural neostigmine in providing labor analgesia. However, no study has evaluated the analgesic effect of epidural butorphanol with neostigmine for the same. MATERIALS AND METHODS: The parturients were randomly allocated to one of the three study groups - Group A (n = 30) received butorphanol 1 mg and neostigmine 7 μg/kg...

BACKGROUND: Dexmedetomidine combined with local anesthetics can decrease the concentration of epidural ropivacaine. However, the optimal dose of epidural dexmedetomidine combined with ropivacaine for labor analgesia is still uncertain. This study investigated the effect of adding different dose of epidural dexmedetomidine to ropivacaine during epidural labor analgesia. METHODS: One hundred women were randomly assigned to one of the four groups (Groups A, B, C, and D received 0...

BACKGROUND: To evaluate the clinical significance of primary symptoms in women with placental abruption. METHODS: A retrospective study of 273 cases of placental abruption was performed. The subjects were classified into two groups according to primary symptoms: 210 cases of the vaginal bleeding group and 63 cases of the abdominal pain group. The clinical features, maternal and neonatal outcomes were compared between two groups. RESULTS: The incidence of preeclampsia and preterm birth in the vaginal bleeding group was significantly lower than abdominal pain group, while the incidence of premature rupture of membrane (PROM) in the former group was higher than that in the latter group...

BACKGROUND: Many stillbirths of normally formed fetuses in the third trimester could be prevented via delivery if reliable means to anticipate this outcome existed. However, because the etiology of these stillbirths is often unexplained and although the underlying mechanism is presumed to be hypoxia from placental insufficiency, the placentas often appear normal on histopathological examination. Gestational age is a risk factor for antepartum stillbirth, with a rapid rise in stillbirth rates after 40 weeks' gestation...

BACKGROUND: Over 3 million stillbirths occur annually in sub Saharan Africa; most occur intrapartum and are largely preventable. The standard of care for fetal heart rate (FHR) assessment in most sub-Saharan African settings is a Pinard Stethoscope, limiting observation to one person, at one point in time. We aimed to test the functionality and acceptability of a wireless FHR monitor that could allow for expanded monitoring capacity in rural Southwestern Uganda. METHODS: In a mixed method prospective study, we enrolled 1) non-laboring healthy term pregnant women to wear the device for 30 min and 2) non-study clinicians to observe its use...

OBJECTIVE: Electronic fetal monitoring (EFM) correlates poorly with neonatal outcome. We present a new metric: the "Fetal Reserve Index" (FRI), formally incorporating EFM with maternal, obstetrical, fetal risk factors, and excessive uterine activity for assessment of risk for cerebral palsy (CP). METHODS: We performed a retrospective, case-control series of 50 term CP cases with apparent intrapartum neurological injury and 200 controls. All were deemed neurologically normal on admission...

Great expectations are connected with application of indirect fetal electrocardiography (FECG), especially for home telemonitoring of pregnancy. Evaluation of fetal heart rate (FHR) variability, when determined from FECG, uses the same criteria as for FHR signal acquired classically-through ultrasound Doppler method (US). Therefore, the equivalence of those two methods has to be confirmed, both in terms of recognizing classical FHR patterns: baseline, accelerations/decelerations (A/D), long-term variability (LTV), as well as evaluating the FHR variability with beat-to-beat accuracy-short-term variability (STV)...

Fetal heart rate monitoring is the process of checking the condition of the fetus during pregnancy and it would allow doctors and nurses to detect early signs of trouble during labor and delivery. The fetal ECG (FECG) signal is so weak and also is corrupted by other signals and noises, mainly by maternal ECG signal. It is so hard to acquire a noise-free, precise and reliable FECG using the conventional methods. In this study, a combination of empirical mode decomposition (EMD) algorithms, correlation and match filtering is used for extracting FECG from maternal abdominal ECG signals...

A pregnancy complicated with rheumatologic diseases can have various influences on the fetus and/or neonate. Maternal systemic lupus erythematosus (SLE) may cause preterm and/or small for gestational age (SGA) delivery and neonatal lupus (NL). Some neonates with NL have congenital heart block (CHB) with increased morbidity and mortality, even requiring pacemakers. Antiphospholipid syndrome may occur with SLE and affect fetal and/or neonatal outcomes. Pregnancy involving primary Sjögren's syndrome (pSS) tends to result in preterm delivery and low birthweight infants...

OBJECTIVE: To evaluate the performance of fetal scalp stimulation (FSS) compared to fetal blood sampling (FBS) as a second line test of fetal wellbeing in labor. STUDY DESIGN: A prospective cohort study was conducted including 298 fetal blood sampling procedures performed due to abnormal fetal cardiotocography (CTG). Two independent observers interpreted the CTG following stimulation. The FSS test was classified as normal when an elicited acceleration and/or provoked fetal heart rate variability was recorded...
