Doppler das artérias umbilicais e cerebral média fetal após sulfato de magnésio na pré-eclâmpsia

Abstract: RESUMO OBJETIVO.Comparar a relação da artéria umbilical e artéria cerebral média fetal através dos índices dopplervelocimétricos (índice de resistência, índice de pulsatilidade e relação S/D) antes e após a utilização do sulfato de magnésio nas gestantes com pré-eclâmpsia grave (pura ou superposta). MÉTODOS. Foi desenvolvido um estudo do tipo coorte prospectivo, no qual cada sujeito serviu como seu próprio controle. Foram selecionadas 40 gestantes com pré-eclâmpsia grave, submetidas ao exame dopplervelocimétri… Show more

“…23 The association between episiotomy and perineal protection in operative births (forceps and extracting vacuum) is the object of other studies. 17,18 However, in the sample studied, no births with the use of forceps were observed, due to their low incidence in the service. Sample size may imply a limitation for assessing some variables; this fact may be considered a limitation of the study.…”

“…Particularly in patients with pregnancy hypertension syndrome, who presented a higher risk for after-birth complications, with hemorrhages, hematomas and infections. 17 The absence of previous vaginal birth also showed to be a risk factor for episiotomy performance, suggesting that perineum, due to its elasticity, may be more prone to vaginal birth after the second birth. In this study a high association was found between the absence of previous vaginal birth and episiotomy performance, remaining significant even after multivariate analysis.…”

“…O diagnóstico de centralização fetal é relativamente frequente 9,10,20 nessas gestações e encontra-se associado com resultados perinatais adversos 9,[15][16][17][18] . No nosso estudo, encontrou-se uma frequência de centralização fetal de 24,0%.…”

“…Outros estudos com diferentes metodologias encontraram uma frequência que variou de 21,9 a 28,4% 16,22 . Todavia, a literatura já descreveu uma elevada frequência de 42,5%, em um subgrupo específico de mulheres com pré-eclâmpsia grave 20 . Atualmente, os autores consideram que a alteração de fluxo da artéria umbilical acima do percentil 95% isolada é suficiente para o diagnóstico de centralização fetal, por se encontrar associada com efeitos adversos perinatais 15,17,22 .…”
