“…Fig. 6 shows the 10th and 90th centiles across some widely used tables in Portugal (Hadlock's and Lubchenco's) [4], a table from a large United States sample from Alexander et al [16] and an international standard-Intergrowth (only 33-42 weeks) [17]. Of note the wide disparity with Alexander's and Lubchenco data, as well as the proximity with data from Hadlock's and Intergrowth newborn data, and the subtle differences with Yudkin's.…”

“…If we compare the 3rd and 97th centiles at 40 weeks (Fig. 5) for boys, a non-ultrasound dated chart widely used in the country [4] (Yudkin's [12]) ranges 1780 g between these centiles, while the current series ranges 1510 g, which more closely resembles Intergrowth's [17] range of 1580 g (also ultrasound dated). The narrower range is caused by precise dates which limit a large source of random variability [19], but also the geographically, socially and ethnically homogenous Portuguese population, compared with intergrowth's [17] sample.…”

“…Given the large number of such charts published over the years, it is up to the clinician to choose one to which compare its population of fetuses/newborns. Such choice and its implications are not always well understood [4] and even professional societies sometimes do not agree on recommendations based on available evidence [5].…”

The use of first trimester ultrasound limits variability by minimizing some random error sources, such as data introduction and GA errors, while allowing better precision (GA in days). This results in a narrower range in the extreme centiles than other charts. Validation with estimates of fetal weight are sound in second and early third trimester fetuses, because that will be a "real world" usage of this standard. While there are similarities between our series and some international/foreign growth charts, other are unfit to characterize our population. This reinforces the need for validation of standards, and sound methodological practices when doing so.

“…Six relevant articles have been identified including the Delphi consensus on definition of FGR: (((((SGA [Title/Abstract]) OR ("fetal growth" [Title/Abstract]) OR (IUGR [Title/Abstract]) OR ("growth restriction" [Title/Abstract]) OR "fetal hypotrophy" [Title/Abstract]))) AND (practice survey)). A summary of those articles is found in the Appendix to this article [2,8,9,[12][13][14][15].…”

Both countries at the time of study also did not have national guidelines regarding growth assessment, making comparisons easier once data collected.…”

Fetal Growth Diagnosis and Management among Perinatal Medical Professionals: A Survey of Practice and Literature Review

et al. 2021

Introduction: This paper aimed to assess the knowledge of healthcare professionals (obstetric and gynecology residents, specialists, and midwives) in the field of perinatal medicine regarding fetal growth diagnosis and management. Methods: A questionnaire was created consisting of a set of questions regarding demographic data, methods of growth assessment, and management. It was a handout survey. The results were analyzed with the use of descriptive statistics and χ2 analysis using the program Statistica. Results: 190 medical professionals have participated in the questionnaire. 86.3% of respondents agreed that pregnancy dating should be modified based on first-trimester ultrasound. 90.9% agreed that III trimester ultrasound has a ±15% margin of error. When asked which growth charts are best fit for assessing growth in a studied population, 10.7% marked standard, 37.4% reference, 26.2% customized, and 26.2% did not know the difference between the three choices. 60.3% stated that they use a growth chart to assess growth and qualify fetuses for monitoring. 70.2% used the 10th centile as a cutoff, 20.1% 5th centile, and 9.7% 3rd centile. Only 40.9% would diagnose fetal growth restriction based on fetal weight only. 28.7% using the 10th centile cutoff, 16.1% 5th centile, and 54.0% 3rd centile. Only a quarter of the respondents were able to name the growth chart or tool that they use for assessment. The most common responses were Yudkin, Hadlock, and online calculators of Fetal Medicina Barcelona and the Fetal Medicine Foundation. Discussion: A lot of confusion is observed primarily in the aspect of cutoff values for identification, subsequent monitoring, and management of fetal growth restriction. There is a need for extensive training and education in this field and uniform national recommendations.

El objetivo de este estudio fue determinar la edad gestacional mediante la obtención de medidas fetales y observación de la organogénesis, utilizando el método ecográfico en hembras caninas que se encontraban en estado de gestación. El estudio se realizó a partir de 15 perras (Canis lupus familiaris) que presentaban un peso promedio de 10 kg, y que asistieron a consulta ginecológica al centro veterinario Cruz Verde, ubicado en la ciudad de Quito-Ecuador. A cada uno de los pacientes se les realizó la respectiva anamnesis, evaluación física, y para deducir un diagnóstico de la edad gestacional se realizó el estudio ecográfico. El método ecográfico permitió diagnosticar que, de 15 hembras revisadas, 14 mostraron signos de gestación y 1 de ellas, aparentemente vacía, pero que al final resultó ser un falso negativo, porque gestó una cría que se desarrolló de forma normal. La duración de la gestación fue de 64 ± 2 días y la correlación entre en el número de vesículas gestacionales y el número de cachorros nacidos fue de 0,89 (P<0,0001), y los latidos cardiacos fueron encontrados después del día 28 de gestación. Además, se logró recomendar la intervención obstétrica quirúrgica (cesárea) en 4 de las 14 (28,6 %) perras diagnosticadas gestantes, en virtud de que sus estados fisiológicos indicaban riesgos de vida, ya sea para la madre o para los cachorros.

Gestational age and fetal growth assessment among obstetricians

Abstract: The role of ultrasound in gestational age assessment and use of EFW use for FGR classification was disparate among participants. EFW and respective centiles may be over relied upon.
