“…The literature provides conflicting results on Apgar scores. For example, one study found no significant difference in 1- and 5-minute Apgar scores of newborns from mothers with DM as compared to a control group ( 23 ), whereas another publication showed that placental changes consistent with reduced blood flow were associated with lower 1- and 5-minute Apgar scores ( 24 ).…”

OBJECTIVES:The current study sought to identify macroscopic placental changes associated with clinical conditions in women with or without diabetes and their newborns.METHODS:The study population consisted of 62 pregnant women clinically diagnosed with diabetes and 62 healthy women (control group).RESULTS:Among the subjects with diabetes, 43 women (69.3%) were diagnosed with gestational diabetes mellitus, 15 had diabetes mellitus I (24.2%), and four had diabetes mellitus II (6.5%). The mean age of the women studied was 28.5±5.71 years, and the mean gestational age of the diabetic women was 38.51 weeks. Of the 62 placentas from diabetic pregnancies, 49 (79%) maternal surfaces and 59 (95.2%) fetal surfaces showed abnormalities, including calcium and fibrin deposits, placental infarction, hematoma, and fibrosis. A statistical association was found between newborn gender and fetal and maternal placental changes (p = 0.002). The mean weight of the newborns studied was 3,287±563 g for women with diabetes mellitus, 3,205±544 g for those with gestational diabetes mellitus, 3,563±696 g for those with diabetes mellitus II, and 3,095±451 g for those with diabetes mellitus I.CONCLUSIONS:Infarction, hematoma, calcification, and fibrin were found on the maternal and fetal placental surfaces in women with diabetes. Women with gestational diabetes and post-term infants had more calcium deposits on the maternal placental surface as compared to those with type I and type II diabetes.

“…Após períodos de hiperglicemia materna e fetal, mesmo quando se obtém controle metabólico materno, nem sempre ocorre o retorno do vLA aos níveis normais. A excessiva movimentação respiratória fetal nos fetos de mães diabéticas também dificulta a correta interpretação dos exames 108 . Nos casos de diabetes mellitus pré-gestacional, do tipo 1, pode haver comprometimento do território placentário e a gestação pode cursar com insuficiência placentária, caracterizada por alteração precoce, a doplervelocimetria das artérias umbilicais e a restrição do crescimento fetal 109 .…”

RevisãoResumo O contexto atual da atividade médica exige do obstetra e ginecologista ampla compreensão dos avanços científicos e tecnológicos de sua área. O objetivo primordial da avaliação fetal antenatal é identificar fetos de risco para eventos adversos ou para o óbito e, assim, atuar preventivamente para evitar o insucesso. O perfil biofísico fetal atinge sua máxima eficiência quando aplicado dentro do contexto clínico de cada caso. Em gestações de alto risco, a doplervelocimetria da artéria umbilical mostrou-se útil para melhorar os resultados perinatais. Na restrição de crescimento fetal por insuficiência placentária grave, antes da 34ª semana de gestação, a doplervelocimetria do ducto venoso tem sido importante instrumento na condução dos casos. Nenhum teste isoladamente é considerado o melhor na avaliação da vitalidade fetal anteparto, entretanto, a análise conjunta de todos os métodos irá propiciar melhor compreensão da resposta fetal à hipóxia. AbstractThe present context of medical practice demands from the obstetrician and gynecologist broad understanding of the scientific and technological advances of the area. The main purpose of prenatal evaluation is to identify fetuses at risk for adverse events or death, for preventive action to avoid mishappenings. The determination of fetal biophysical profile reaches its maximum efficiency when applied within the clinical context of each case. In high risk gestations, the Doppler velocimetry of the umbilical artery has shown to be useful to improve perinatal outcome. In the fetal growth deficit, due to severe placentary insufficiency, Doppler velocimetry of the venous duct has been showing to be an important tool in handling of the cases before the 34 th week of gestation. Although no test itself is considered the best to evaluate the fetus's prenatal vitality, the joint analysis of all methods may lead to a better understanding of the fetal response to hypoxia.
