Popis: | The objective of this study was to evaluate the effect of preeclampsia and its severity on maternal mean middle cerebral artery blood flow velocity (mean MCA-CBFV) using transcranial doppler sonography (TCD), as well as the effect of magnesium on mean MCA-CBFV in preeclampsia.This study used a prospective, comparative design. TCD was used to examine maternal mean MCA-CBFV in both healthy subjects (controls) and preeclamptic subjects (cases). The two groups were similar in age, gestational age, and parity. Healthy subjects were categorized into three groups: Group I, 6–14 weeks, n = 10; Group 11, 24–40 weeks, n = 27; Group HI, postpartum n = 15, 12–36 h. Serial TCD examinations of the middle cerebral artery were completed in 21 preeclamptic subjects at four different points in time: Time I is an initial measurement before delivery; Time 2 is also before delivery but after magnesium had been administered; Time 3 is postpartum while on magnesium (12–24 h), Time 4 is postpartum off magnesium, (24–48 h).Preecl... |
