High volume on line hemodiafiltration in dialysis pregnant patients: predilutional or postdilutional?

Although the frequency of pregnancy in women on chronic dialysis is extremely low, it is associated with severe maternal and perinatal morbidity and mortality. This situation represents a challenge for the therapeutic team, which requires multidisciplinary management, as well as measures to adequate dialysis treatment. Such efforts include increasing the time and frequency of dialysis session, maintaining low uremia levels and ensuring hemodynamic stability by avoiding intra-treatment arterial hypotension and hydro electrolytic fluctuations.
