Bioelectrical impedance analysis in the clinical management of a pregnant woman undergoing dialysis.
We report a case of successful pregnancy in a woman who was initially diagnosed with renal failure in mid-pregnancy. She was started on hemodialysis, and her fluid balance was serially monitored with bioelectrical impedance analysis. Her body weight decreased and bioelectrical impedance values increased, along with resolution of pulmonary edema in the process of the removal of excessive fluid retention with hemodialysis. The bioelectrical impedance values decreased immediately after the usual dose of oral ritodrine was administered, partly because producing sodium and water retention by ritodrine were enhanced in the setting of fluid imbalances. This decrease preceded the onset of pulmonary edema, while no changes were noted in maternal body weight before hemodialysis. These results suggest that the serial measurement of bioelectrical impedance values enables more reliable and earlier detection of abnormal water retention in pregnant women undergoing dialysis than the effect of body weight changes.
