RESUMO
OBJECTIVE: To evaluate maximal respiratory pressures, pulmonary volumes and capacities and exercise functional capacity in pregnant women with preeclampsia. METHOD: Primigravid women with preeclampsia and healthy primigravid women were evaluated by means of manovacuometry, spirometry and the 6-minute walk test. RESULTS: The group with preeclampsia showed higher minute ventilation and lower forced vital capacity and exercise tolerance. The presence of preeclampsia and forced vital capacity were predictors in the six-minute walk test. CONCLUSION: Preeclampsia showed significant alterations in the respiratory system and was associated with lower exercise tolerance; however, it did not affect respiratory muscle functions.

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.
