Objectives The objective was to assess the composite neonatal morbidity (CNM) among diabetic women with sonographic estimated fetal weight (SEFW) at 10 to 90th versus >90th percentile for gestational age (GA). Study Design The inclusion criteria for this retrospective study were singleton pregnancies at 34 to 41 weeks, complicated by diabetes, and that had SEFW within 4 weeks of delivery. Odds ratios (ORs) with 95% confidence intervals (CI) were calculated. Results Among the 140 cohorts that met the inclusion criteria, 72% had SEFW at 10th to 90th percentile for GA, and 28% at >90th percentile. Compared with women with diabetes with last SEFW at 10th to 90th percentile, those with estimate > 90th percentile for GA had a significantly higher rate of CNM (13 vs. 28%; OR, 2.65; 95% CI, 1.07–6.59). Among 109 diabetic women who labored, the rate of shoulder dystocia was significantly higher with SEFW at >90th percentile for GA than those at 10th to 90th percentile (25 vs. 2%; p = 0.002); the corresponding rate of CNM was 29 versus 10% (p = 0.02). Conclusion Among diabetic women with SEFW > 90th percentile for GA, CNM was significantly higher than in women with estimate at 10 to 90th percentile. Despite the increased risk of CNM, these newborns did not have long-term morbid sequela.

Estimated Fetal Weight

Objectives: The identification of at-risk fetus is considered as one of the most difficult challenges for clinicians and researchers although the clinical significance of placental calcifications (PCs) and its relation to adverse pregnancy outcome are controversial. Therefore, the present study aimed to evaluate the relationship between PC and estimated fetal weight (EFW) percentile at 30-34 weeks of pregnancy. Materials and Methods: This prospective cross-sectional study was carried out on all pregnant women except for multiple pregnancy subjects who were admitted to an outpatient perinatal center from October 2016 to September 2018. Several parameters were measured at 30-34 weeks of pregnancy, including EFW, umbilical artery pulsatility index (PI), middle cerebral artery PI, cerebroplacental ratio (CPR), right and left uterine artery PI, along with right and left uterine artery notch. Finally, the calcification of the placenta with any shape and degree was determined as well. Results: In this study, 739 pregnant women were evaluated for PC, including patients with PC (9.87%), small-for-gestational age (SGA, 3.65%), and those with at least one abnormal Doppler index (23.95%). Patients with PC and those with at least one abnormal Doppler index had significantly higher SGA (29.62% and 12.42%, respectively). In addition, there were 55.55% and 30.13% patients with SGA and PC in the group with at least one abnormality in terms of Doppler indices. Conclusions: In general, the findings showed that PC is more common in SGA. Based on the results, at least one abnormality in Doppler indices was more common in PC and SGA, and uterine artery Doppler abnormality was the most prevalent abnormal findings in the arterial Doppler. Thus, PC may be an important marker for adverse pregnancy outcomes.

Singleton Pregnancies

AbstractUltrasonic assessment of fetal weight derived from multiple measurements of the fetus has become accepted in clinical practice as being useful in singleton pregnancies. Several different formulae for estimating fetal weight have been derived from differing measurements of the fetus, such as biparietal diameter, trunk circumference, and femur length. To date, there has been no attempt to evaluate such a technique in multiple pregnancy. This study aims to see whether the formulae derived for singleton pregnancy are applicable to twin pregnancies. Estimated fetal weight will be derived by mathematical modelling from ultrasonic measurements made within a week of delivery and the results compared with the actual birthweight to give an indication of how good such estimated fetal weights are. Factors to be considered in the analysis include whether there are differences between Twin I and Twin II, differences of presentation with twins and differences by gestation at delivery.

Estimated Fetal Weight

Background: In obstetric management fetal weight estimation is an important consideration when planning the mode of delivery in our day to day practice. In Bangladesh low birth weight is a major public health problem & incidence is 38% - 58%. Neonatal mortality and morbidity also yet high. So accurate antenatal estimation of fetal weight is a good way to detect macrosomia or small for date baby. Thus to improve the pregnancy outcome and neonatal outcome decreasing various chance of neonatal mortality and morbidity antenatal fetal weight prediction is an invaluable parameter in some situation where to identify the at risk pregnancy for low birth weight become necessary. Reliable method for prenatal estimation of fetal weight two modalities have got popularity - Clinical estimation and another one is ultrasonic estimation. This study was designed to determine the accuracy of clinical versus ultrasound estimated fetal weight detecting the discrepancy with actual birth weight at third trimester. So that we can verify more reliable and accurate method. Objectives: To find out more accurate and reliable modality of fetal weight estimation in antenatal period during obstetric management planning. To compare clinical versus ultrasound estimated fetal weight & to determine discrepancy of both variable with actual birth weight. Method: This prospective, cross sectional analytical study was carried out in Dhaka Medical College Hospital from January 2006 to December 2006. By purposive sampling 100 pregnant women fulfilling inclusion criteria were included in my study in third trimester (29wks-40wks). In clinical weight estimation procedure SFH (Symphysio Fundal Height) was measured in centimeter. On pervaginal finding whether vertex below or above the ischial spine was determined. By Johnson’s formula fetal weight in grams was estimated. Then by ultrasound scan different biometric measurements were taken and finally by Hadlock’s formula fetal weight was estimated. Eventually actual birth weight was taken after birth by Globe Brand weighing machine. Accuracy of both modalities were compared and which one was more reliable predictor was determined by statistical analysis. Results: After data collection were analyzed by computer based software (SPSS). There was gradual and positive relationship between symphysiofundal height and estimated birth weight. Discrepancy between clinical and actual birth weight at third trimester was statistically significant – Paired Student’s ‘t’ test was done where p value was <0.001. Whereas discrepancy between sonographically estimated fetal weight with actual birth weight was not statistically significant (by paired ‘t’ test where p value was >0.05). That implies discrepancy between ultrasound estimated fetal weight and actual birth weight was significantly less than that of clinically estimated fetal weight. 14% clinically and 46% sonographically estimated fetal weight were observed within £ 5% of actual birth weight. 31% clinical and 42% sonographically estimates observed within 6% to 10% of actual birth weight and 55% clinical and 12% sonographically estimate were >10% of actual birth weight. That is about 88% sonographical versus 45% clinical estimates were within 10% of actual birth weight. Conclusion: There is no doubt about importance of fetal weight in many obstetric situations. Clinical decisions at times depends on fetal weight. Whether to use oxytocin, to use forceps or vacuum for delivery or extend of trial or ended by Caesarian section immediately or no scope of trial to be largely depend on fetal size and weight. So more accurate modality for antenatal fetal weight estimation has paramount importance. In my study sonographically estimated weight have more accuracy than that of clinical estimate in predicting actual birth weight. Sonographically estimated fetal weight is more reliable, accurate and reproducible rather than other modality. J Shaheed Suhrawardy Med Coll, June 2019, Vol.11(1); 32-38

AbstractFetal growth restriction is a strong risk factor for perinatal morbidity and mortality. Reliable standards are indispensable, both to assess fetal growth and to evaluate birthweight and early postnatal growth in infants born preterm. The aim of this study was to create updated Swedish reference ranges for estimated fetal weight (EFW) from gestational week 12–42. This prospective longitudinal multicentre study included 583 women without known conditions causing aberrant fetal growth. Each woman was assigned a randomly selected protocol of five ultrasound scans from gestational week 12 + 3 to 41 + 6. Hadlock’s 3rd formula was used to estimate fetal weight. A two-level hierarchical regression model was employed to calculate the expected median and variance, expressed in standard deviations and percentiles, for EFW. EFW was higher for males than females. The reference ranges were compared with the presently used Swedish, and international reference ranges. Our reference ranges had higher EFW than the presently used Swedish reference ranges from gestational week 33, and higher median, 2.5th and 97.5th percentiles from gestational week 24 compared with INTERGROWTH-21st. The new reference ranges can be used both for assessment of intrauterine fetal weight and growth, and early postnatal growth in children born preterm.

AbstractObjectivesOur aim was to study the association of clinical variables obtainable before delivery for severe neonatal outcomes (SNO) and develop a clinical tool to calculate the prediction probability of SNO in preterm prelabor rupture of membranes (PPROM).MethodsThis was a prospective study from October 2015 to May 2018. We included singleton pregnancies with PPROM and an estimated fetal weight (EFW) two weeks before delivery. We excluded those with fetal anomalies or fetal death. We examined the association between SNO and variables obtainable before delivery such as gestational age (GA) at PPROM, EFW, gender, race, body mass index, chorioamnioitis. SNO was defined as having at least one of the following: respiratory distress syndrome, intraventricular hemorrhage, necrotizing enterocolitis, neonatal sepsis, or neonatal death. The most parsimonious logistic regression models was constructed using the best subset selection model approach, and receiver operator curves were utilized to evaluate the prognostic accuracy of these clinical variables for SNO.ResultsWe included 106 pregnancies, 42 had SNO (39.6%). The EFW (area under the receiver operating characteristic curve [AUC]=0.88) and GA at PPROM (AUC=0.83) were significant predictors of SNO. The addition of any of the other variables did not improve the predictive probability of EFW for the prediction of SNO.ConclusionsThe EFW had the strongest association with SNO in in our study among variables obtainable before delivery. Other variables had no significant effect on the prediction probability of the EFW. Our findings should be validated in larger studies.
