Background Expectations and knowledge of pregnant women prior to fetal ultrasound are well documented in developed countries. Women have generally been shown to have appropriate and reasonable expectations and knowledge. The main objective of this study was to examine whether the views of women in our setting are similar to findings from studies in developed countries. Methods This was a descriptive study done on pregnant women attending the ultrasound department and antenatal clinic at Rahima Moosa Mother and Child Hospital. An interview questionnaire was administered before the ultrasound scan. Results Two hundred and fifty women were recruited. The most frequently expressed expectation was to determine sex of baby (n=154). This was followed by wanting to know the baby’s wellbeing and health (n=136). All the women interviewed had expectations. The majority of women did not know that fetal anomalies could be detected at fetal ultrasound (n=235), this was statistically significant (p=0.003) and was correlated to educational level. Almost half the women did not know the purpose of the ultrasound for which they were referred for (n=124). Conclusion Most women had appropriate expectations in keeping with studies from developed countries. Lack of education was directly linked to poor knowledge of fetal ultrasound. This study has identified areas where patient education is needed regarding fetal ultrasounds. / LG2018

Introduction: An assessment of the role of Doppler ultrasound velocity waveform analysis of the fetal umbilical arteries in the diagnosis of fetal distress in labour is made from a review of the literature and clinical study. Study objectives: 1) To determine the value of screening with Doppler ultrasound in high-risk labours in the prediction of the development of indicators of fetal distress. 2) To determine whether Doppler velocimetry indices of the umbilical arteries change with the development of indicators of fetal distress in labour. Design: Repeated Doppler velocimetry in selected high risk labours. Setting: Groote Schuur Hospital, Cape Town, South Africa, a large tertiary referral centre. Subjects: Thirty six women with singleton pregnancies complicated either by gestational proteinuric hypertension or by intrauterine growth retardation or both with a normal cardiotocographic tracing at the onset of labour. Main outcome measures: 1) Acid-base status of the fetus was assessed after deli very by analysis of umbilical artery blood. 2) Apgar score was recorded at 1 and 5 minutes. 3) Neonates were carefully examined for clinical signs of perinatal hypoxia. Results: Twenty seven fetuses were followed through labour. No relation was found between umbilical artery Pourcelot ratio (resistance index) on admission in labour and umbilical artery base deficit. Six fetuses were born with an umbilical artery base deficit of more than 10 mmol 1-1. Zero change in mean Pourcelot ratio was noted in both normal and acidotic fetuses. None of the acidotic fetuses showed a change in Pourcelot ratio of more than 0.03. The study had an 80% power to detect a change in mean Pourcelot ratio of 0.07 in the normal fetuses and 0.16 in the acidotic fetuses at a 95% confidence level. No relation was found between Pourcelot ratio on admission in labour or change in Pourcelot ratio during labour and Apgar score. None of the neonates showed clinical signs of perinatal hypoxia. Conclusions: Doppler velocimetry of the umbilical arteries in labour as measured by the Pourcelot ratio does not contribute to the diagnosis of fetal distress in labour.

O objetivo deste estudo foi avaliar e comparar a eficácia da estimativa ultra-sonográfica e clínica na predição do peso fetal; analisar fatores maternos e fetais que poderiam interferir na estimativa ultra-sonográfica do peso fetal. Foram realizadas 212 avaliações, em até 24 horas do parto. Os fatores maternos avaliados foram peso, IMC e distância entre a pele e o útero; e os fetais constaram de apresentação, posição de dorso, localização e espessura placentárias, peso fetal e ILA. A estimativa ultra-sonográfica do peso fetal apresenta boa acurácia, já a clínica mostrou-se satisfatória na predição do peso no nascimento, embora com desempenho inferior à avaliação ultra-sonográfica. Quanto maior a distância entre a pele e o útero materno e quanto menor o peso fetal maior o erro na estimativa do peso / This study was designed to evaluate the accuracy of ultrasound and clinical fetal weight estimation; evaluate maternal and/or fetal factors that could interfere in ultrasound estimation of fetal weight and, compare the accuracy of ultrasound versus clinical fetal weight estimations. 212 estimation of fetal was performed within 24 hours to delivery. The maternal factors examined were: weight, BMI, skin to uterus distance, and as fetal factors: presentation, position, fetal weight, placental localization and thickness and AFI. Ultrasound presented good accuracy in the estimation of fetal weight. Thick distances between skin to uterus and small fetuses are associated to higher errors in estimating fetal weight. Clinical estimation of fetal weight was satisfactory in the prediction of birth weight, however with lower accuracy than ultrasound

Most causes of congenital anomaly (CA) remain still not elucidated; however it is known that genetic and environmental factors can increase the risk of developing these pathologies. The risk factors associated to pregnant women have been highlighted by its ability to influence conception results. Objective. Establish the clinical-epidemiological risk factors to CA. Methods. An observational, prospective, longitudinal, case-control study, performed between November 2014 and January 2016, in a fetal medicine service. The case population consisted of 223 pregnant women with fetuses carrying SA, and the control population consisted of 134 pregnant women without congenital structural anomalies. To evaluate the clinical and epidemiological data of pregnant women participating in the study, a questionnaire was applied for both groups before pre-natal visit. Later, after fetuses SA diagnosis, realized during ultrasonography evaluation, the groups were divided in case group and control group. Results. No significant differences were found in relation to age (p: 0.884), ethnicity (p: 0.887) and number of previous pregnancies (p: 0.139) between both evaluated groups. However, there were significant statistical differences between case group and control group regarding abortion history (OR: 2.05), previous children with CA (OR: 3.85), familiar CA history (OR: 6.03), consanguinity (OR: 4.43) and consumption of teratogenic substances during pregnancy (OR: 5.65). The most frequent SA were central nervous system (CNS) anomalies (30.94%), followed by genitourinary system (GUS) anomalies (23.80%) and by multiple congenital anomalies (MCA) (16.60%). The fetal gender most affected by structural anomalies was the male gender (52.12%). The most frequent final evolution of pregnancies with fetuses carrying SA was the birth (68.61%). Conclusion. The risk factors that influenced the congenital anomaly occurrence were: previous abortion, history of children with previous CA, familial history of CA, inbreeding and teratogenic substances use during pregnancy. / Introdução. A maioria das causas de anomalias congênitas (AC) ainda permanece não elucidada, no entanto, sabe-se que fatores genéticos e ambientais podem aumentar o risco de desenvolvimento destas patologias. Os fatores de risco associados às gestantes têm sido destacados por sua capacidade de influenciar nos resultados da concepção. Objetivo. Estabelecer os fatores de risco clínico-epidemiológicos para AC. Métodos. Estudo observacional, prospectivo, longitudinal, do tipo caso-controle, realizado entre novembro de 2014 a janeiro de 2016, em um serviço de medicina fetal. A população caso foi composta por 223 gestantes com fetos portadores de AE, e a população controle por 134 gestantes sem anormalidades congênitas estruturais. Para avaliar os dados clínicos e epidemiológicos das gestantes participantes da pesquisa, foi aplicado um questionário para ambos os grupos antes da consulta pré-natal. Posteriormente, após diagnóstico de AE fetal, realizado durante a avaliação ultrassonográfica, foram divididas em grupo caso e grupo-controle. Resultados. Não foram encontradas diferenças significativas em relação à idade (p: 0,884), etnia (p: 0,887) e número de gestações prévias (p: 0,139) entre os dois grupos avaliados. Entretanto, houve diferenças estatísticas entre o grupo caso e o grupo-controle quanto a antecedentes de abortos (OR: 2,05), filhos anteriores com AC (OR: 3,85), histórico de AC familiar (OR: 6,03), consanguinidade (OR: 4,43) e consumo de substâncias teratogênicas durante a gestação (OR: 5,65). As AE mais frequentes foram as anomalias do sistema nervoso central (SNC) (30,94%), seguida das anomalias do sistema gênitourinário (SGU) (23,80%) e das múltiplas anomalias congênitas (MAC) (16,60%). O sexo fetal mais acometido por anormalidades estruturais foi o sexo masculino (52,12%). A evolução final da gestação de fetos portadores de AE mais frequente foi o nascimento (68,61%). Conclusão. Os fatores de risco que influenciaram a ocorrência de anomalia congênita foram: abortamento prévio, antecedentes de filhos com AC prévia, história familiar pregressa de AC, consanguinidade e uso de substâncias teratogênicas durante a gestação.
