“…The risk of miscarriage decrease by going forward in GA and the most serious period is the first two weeks after detection of slow FHR at 6 th week which can be used as an early predictor of miscarriage and that agreed with Kosus et al [9] who said that while evidence of abnormal embryonic heart rate [EHR] may indicate poor prognosis and higher risk of spontaneous miscarriage, routine assessment of EHR may be used as a prognostic tool for miscarriage.…”

Background: Miscarriage is the most common adverse pregnancy outcome which has detrimental psychological consequences for the woman and her partner and delays successful childbearing. Normal embryonic heart rate is about [100-200] bpm at 5 weeks gestation then it increases progressively over the subsequent 2-3 weeks. Fetal demise often occurs within one week after the slow embryonic heart rate and always occurs by the end of the first trimester. Aim of the work: The aim of the present study was to investigate the relation between first trimester miscarriage and slow embryonic heart rate at sixth week of gestational age and other risk factors of miscarriage. Patients and methods: A prospective observational cohort study was conducted in the department of Obstetrics and Gynecology, Al-Azhar Faculty of medicine [Damietta] during the period from September 2017 to September 2018 on 90 pregnant women who had slow embryonic heart rate [80-100] bpm at sixth week of gestational age. All were submitted to full history taking, clinical and ultrasound examination and followed up till the end of their pregnancy and outcome was documented. Results: Percentage of aborted cases at the 8 th week of gestational age was [38.9%], while, [20%] at the 10 th week and [15.4 %] at 13 th week. Whom fetus had a heart rate less than 90 were at risk 23.8 times for experiencing abortions more than other females. Conclusion: Slow embryonic heart rate is one of the earliest predictors for the first trimester fetal demise and it is one of the newest studies.

“…In spite of being a method with proven accuracy both in vitro and in vivo studies ( 7 , 8 ) , 3DUS is still an expensive technique available only in few reference centers in the world, particularly in developed countries. For small fetal structures with little irregularities, 2DUS could be utilized for being an appropriate and low-cost method, besides being accessible to a higher number of clinicians and investigators ( 9 , 10 ) .…”

ObjectiveTo establish reference intervals for the fetal cisterna magna volume by means of two-dimensional (2D) method using the multiplanar mode of three-dimensional ultrasonography.Materials and MethodsCross-sectional study with 224 healthy pregnant women between the 17th and 29th gestational weeks. The volume was automatically obtained by multiplying the three major axes in axial and sagittal planes by the constant 0.52. Polynomial regression was utilized to establish the correlation between fetal cisterna magna volume and gestational age, with adjustments by coefficient of determination (R2). Reliability and agreement were obtained by intraclass correlation coefficient (ICC) and limits of agreement, respectively.ResultsMean fetal cisterna volume with the 2D method ranged from 0.71 ± 0.19 cm3 to 4.18 ± 0.75 cm3 at the 17th and 29th weeks, respectively. The authors observed a good correlation between fetal cisterna magna volume and gestational age (R2 = 0.67), excellent intraobserver reliability and agreement with ICC = 0.89 and limits of agreement 95% (-52.0; 51.8), respectively, and low interobserver reliability and agreement with ICC = 0.64 and limits of agreement 95% (-110.1; 84.6), respectively.ConclusionReference intervals for fetal cisterna magna volume by means of 2D method using the multiplanar mode of three-dimensional ultrasonography were established and presented excellent intraobserver reliability and agreement.

First trimester volumetric measurements: relation with hormone levels and fetal heart rate

Abstract: Various ranges of relations are observed between FHR, obstetric, and hormonal measurements. The relationship between these parameters might be used for determination of abnormal growth and adverse outcomes in early pregnancy.
