Bioimpedance in pregnant women with preeclampsia.
To analyze the direct (resistance and reactance) and indirect (intra and extracellular total body water) BIA parameters in preeclamptic women, 51 healthy pregnant women and 65 preeclamptic women were submmited to bioelectric impedance on the third trimester of gestation. The significance value adopted was 5%. Preeclamptic women showed lower values for R (448 Ω vs. 542 Ω), Rc (40 Ω vs. 53 Ω) and ICW (49.45% vs. 51%) when compared to control group. They also showed higher values for TBW (49% vs. 47%), TBWcor (41.6% vs. 34%) and ECW (50% vs. 47%). Bioelectric impedance allowed differentiating preeclamptic women from health pregnant women, indicating that preeclampsia changes body compartments during pregnancy. This method can help understand the mechanisms involved in preeclampsia and to be a prediction away of preeclampsia.
