Abstract

Abstract: Pregnant woman undergoing dialysis face challenges such as miscarriage and stillbirth when carrying a baby to term. A complication of prenatal care is the difficulty in properly managing body fluids. We compare fluid volumes between healthy pregnant women and two pregnant women undergoing dialysis using bioelectrical impedance analysis (BIA). Data of 52 healthy pregnant women at various stages of their pregnancy were analyzed for the study. We included these many cases so as to collect sufficient data to compare them with our two cases of women undergoing dialysis who successfully completed their term deliveries. Fluid volumes were measured every week before and after dialysis using BIA. We also measured the levels of human atrial natriuretic peptide after dialysis. During dialysis, the dry weight (DW) of pregnant patients is altered based on the state of the amniotic fluid and fetus. However, evaluating body fluid and DW using radiography is difficult in pregnant women. BIA offers a mostly harmless alternative for such measurements. Using BIA, we were able to easily measure body fluid volume and change the setting of DW for dialysis. Thus, our successful example can serve as a reference for future cases of pregnant women undergoing dialysis. Nevertheless, given that the state of the fetus and amniotic fluid affect the results of dialysis, it is important that we use not only BIA but also a comprehensive evaluation to determine dialysis settings in pregnant women.
