Objectives: To evaluate the effect of intensive fetal surveillance via Doppler ultrasound and fetal non-stress test on the perinatal outcome of pregnant women undergoing an intensified hemofiltration scheme.
Methods: Five consecutive pregnancies of women undergoing intensified hemodialysis were analyzed due to the following parameters: maternal background, hemodialysis schedule during pregnancy, blood pressure, occurrence of fetal complications, occurrence of obstetric complications, gestational week at delivery, mode of delivery, and newborn outcome and follow-up.
Results: All pregnancies resulted in a live birth, mean gestational age was 32 weeks. Intrauterine growth restriction occurred in 4 fetuses, pathological umbilical artery flow velocity waveforms in 2. The mean birth weight was 1,764 g (range 1,274-2,465 g). Cesarean section was performed in 3 patients because of fetal distress. None of the patients developed severe complications like pre-eclampsia.
Conclusions: Although intensified dialysis enables the maintenance of stable uteroplacental and fetal perfusion, intensive fetal monitoring is mandatory to reduce perinatal morbidity and mortality in pregnant women on maintenance dialysis.
