“…4,9,11,19,21 Despite the lack of a single reliable method to identify fetal growth deviations, combined clinical and ultrasound methods improve diagnosis. 5,6,15,18 As for the diagnosis of fetal growth restriction, newborn's weight is only a fi nal measurement which does not allow any kind of intervention to manage fetal weight gain. 5,6 On the other hand, fetal weight estimates using ultrasound provides data that enable to diagnose conditions that may be impairing fetal growth.…”

“…9 Some other studies have investigated curves developed from a Brazilian population of pregnant women, however these curves differ methodologically from the present curve, especially in the SFH measurement technique and variation between examiners. 18 Although Neilson 20 claimed there is a lack of evidence indicating any real benefi t of using SFH measurement in prenatal care, many countries have prenatal care protocols recommending its use along with reference curves designed for the population of interest. Despite technological improvements, the real benefi t of obstetric ultrasound, when used in the clinical routine as a screening method for fetal growth restriction in low-risk populations, is not yet supported by strong scientifi c evidence.…”

“…The Brazilian Ministry of Health (BMoH) recommends the use of a standard SFH curve developed by Fescina et al 9 Normal uterine growth is within the 10 th and the 90 th percentiles. b However, studies have reported different SFH patterns for Brazilian populations, 10,18,21 and these differences could be explained not only by specifi c characteristics of ethnic groups but also by other factors such as different measurement techniques, risk level, socioeconomic and nutritional conditions, gestational age estimates and number of examiners.…”

OBJECTIVE:To validate a new symphysis-fundal curve for screening fetal growth deviations and to compare its performance with the standard curve adopted by the Brazilian Ministry of Health. METHODS:Observational study including a total of 753 low-risk pregnant women with gestational age above 27 weeks between March to October 2006 in the city of João Pessoa, Northeastern Brazil. Symphisys-fundal was measured using a standard technique recommended by the Brazilian Ministry of Health. Estimated fetal weight assessed through ultrasound using the Brazilian fetal weight chart for gestational age was the gold standard. A subsample of 122 women with neonatal weight measurements was taken up to seven days after estimated fetal weight measurements and symphisys-fundal classifi cation was compared with Lubchenco growth reference curve as gold standard. Sensitivity, specifi city, positive and negative predictive values were calculated. The McNemar χ 2 test was used for comparing sensitivity of both symphisys-fundal curves studied. RESULTS:The sensitivity of the new curve for detecting small for gestational age fetuses was 51.6% while that of the Brazilian Ministry of Health reference curve was signifi cantly lower (12.5%). In the subsample using neonatal weight as gold standard, the sensitivity of the new reference curve was 85.7% while that of the Brazilian Ministry of Health was 42.9% for detecting small for gestational age. CONCLUSIONS:The diagnostic performance of the new curve for detecting small for gestational age fetuses was signifi cantly higher than that of the Brazilian Ministry of Health reference curve.

“…Contudo, os métodos clínicos e ultrassonográficos, se utilizados em conjunto, aumentam a possibilidade de se efetuar corretamente esse diagnóstico 5 . Como o teste de rastreamento ideal deveria ser de rápida aplicação, baixo custo, seguro e muito sensível para identificar a maioria dos casos 6 , a estimativa de peso fetal por ultrassonografia (USG) tem sido proposta como um bom método diagnós-tico para RCF 7 .…”

OBJETIVO: avaliar a correlação entre o peso fetal estimado (PFE) por ultrassonografia e o peso neonatal (PN), bem como a capacidade do PFE predizer as alterações do PN entre gestantes de João Pessoa (PB). MÉTODOS: estudo de validação diagnóstica incluindo 122 gestantes que tiveram o PFE calculado por ultrassonografia até sete dias antes do parto e o PN determinado imediatamente após o nascimento, com balança específica para recém-nascidos. A correlação entre o PFE e o PN foi avaliada pelo coeficiente de correlação de Pearson entre as duas medidas e pela média das diferenças entre elas. O PFE e o PN foram classificados em: pequeno para idade gestacional (PIG), adequado para a idade gestacional (AIG) e grande para a idade gestacional (GIG), de acordo com os percentis 10 e 90 das respectivas curvas de referência. O diagnóstico de desvios do PFE foi validado utilizando a curva de valores de referência de peso neonatal de Alexander como padrão-ouro, estimando-se a sensibilidade, especificidade, valores preditivos positivo e negativo. RESULTADOS: houve uma elevada correlação linear entre o PFE e o PN (R=0,96) e a diferença entre eles variou entre -474 g e +480 g, com média de +3 g. A maioria das máximas variações percentuais da estimativa de peso esteve entre 10 e 15%. O PFE teve sensibilidade de 85,7% e especificidade de 100% para detecção de PIG, e de 100 e 77,2%, respectivamente, para GIG. CONCLUSÕES: o PFE é capaz de predizer adequadamente o PN, e a curva de PFE de referência testada teve bom desempenho no rastreamento dos desvios do crescimento fetal, quando utilizada nessa população.Abstract PURPOSE: to evaluate the correlation between the estimated fetal weight (EFW) by ultrasonography and the neonatal weight (NW), as well as the EFW's capacity to predict changes in NW among pregnant women in João Pessoa, Paraíba, Brazil. METHODS: a diagnostic validation study, including 122 pregnant women who have had the EFW calculated by ultrasonography up to seven days before delivery and the NW established immediately after birth, with a specific newborn's scale. The correlation between EFW and NW measurements was assessed by Pearson's correlation coefficient and by the mean difference between them. EFW and NW were classified as: low for the gestational age (LGA), adequate for the gestational age (AGA) and high for the gestational age (HGA), according to the percentiles 10 and 90 of the respective reference curves. The diagnosis of EFW deviation has been validated using the values of the Alexander's NW reference curve as gold-standard, by estimating the sensitivity, specificity, and positive and negative predictive values. RESULTS: there has been a high linear correlation between the EFW and NW (R=0.96), and the difference between them has varied from -474 g to +480 g, with an average of +3 g. Most of the highest percent weight estimate variations were between 10 and 15%. EFW has had 85.7% of sensitivity and 100% of specificity for the detection of LGA, and 100 and 77.2%, respectively, for the detection of HGA. CONCLUSIONS...

“…O gráfico recomendado pelo MS do Brasil foi elaborado a partir de dados do Centro Latino-Americano de Perinatologia (CLAP). Entretanto, há autores (9) que têm demonstrado discrepância entre os valores de curvas de AU apresentadas na literatura quando aplicadas a populações diferentes das que forneceram os parâmetros para sua construção (10)(11)(12)(13)(14)(15)(16)(17) . As diferenças observadas foram explicadas não apenas pelo caráter regional das diferentes curvas, mas também por fatores como a técnica de medição da AU.…”

ReSUmOEstudo longitudinal e prospectivo que procurou quantificar a variabilidade intra e interobservadores da medida da altura uterina (AU) e verificar a contribuição de um curso capacitatório para enfermeiros e graduandos de Enfermagem no viés de aferição da medida. Foram selecionados dois participantes, que realizaram duas medidas em vinte gestantes antes e após o curso. Calculou-se a variabilidade intra e interobservadores, o coeficiente de correlação intraclasse, o erro técnico de medida absoluto e relativo e a fiabilidade da medida. O teste t pareado mostrou redução estatisticamente significante (p=0,0396) no viés de aferição. Conclui-se que a capacitação de enfermeiros e graduandos de Enfermagem na técnica de medição da AU reduz significativamente a variabilidade intraobservador e interobservadores. descritores: Assistência Pré-Natal; Precisão; Ensino; Enfermagem; Graduação. aBStRaCt A prospective, longitudinal study sought to quantify the intra and inter-observer variability of the uterine height (UH) measurement and verify the contribution of a training course for nurses and nursing students in measurement bias. We selected two participants who performed two measurements in 20 pregnant women before and after the course. We calculated the intra and inter-observer variability, the coefficient of intraclass correlation, the absolute and relative technical error of measurement and the measure reliability. The paired t test showed a statistically significant reduce (p = 0.0396) in the measurement bias. We conclude that the training of nurses and nursing students in the technical measurement of UH significantly reduces intra and inter-observer variability.
