Abstract

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.

摘要

为分析子痫前期妇女的直接（电阻和电抗）和间接（细胞内和细胞外总体水）生物电阻抗分析（BIA）参数，对51名健康孕妇和65名子痫前期妇女在妊娠晚期进行了生物电阻抗检测。采用的显著性值为5%。与对照组相比，子痫前期妇女的R（448Ω对542Ω）、Rc（40Ω对53Ω）和ICW（49.45%对51%）值较低。她们的TBW（49%对47%）、TBWcor（41.6%对34%）和ECW（50%对47%）值也较高。生物电阻抗能够区分子痫前期妇女和健康孕妇，表明子痫前期在孕期会改变身体组成部分。这种方法有助于了解子痫前期的发病机制，并可用于子痫前期的预测。
