Which strategy is commonly used to balance fluid management in PD during pregnancy?

• A. Careful adjustment of ultrafiltration goals and close obstetric coordination.
• B. Maintain a fixed ultrafiltration target regardless of pregnancy stage.
• C. Stop PD during pregnancy.
• D. Only increase dialysate glucose to drive ultrafiltration.

Answer: (A)

Balancing fluid management in pregnancy while on peritoneal dialysis hinges on tailoring how much ultrafiltration you aim for and coordinating closely with the obstetric team. During pregnancy, a woman’s fluid status and hemodynamics change as the uterus grows, plasma volume expands, and placental perfusion becomes a key concern. PD provides continuous fluid removal, but the amount of ultrafiltration needed can vary over the course of the pregnancy. By actively adjusting ultrafiltration goals—through changes in dwell times, exchange volumes, and potentially the dialysate’s osmotic gradient—you can maintain euvolemia, avoid edema or hypotension, and support both maternal and fetal well-being. Why this approach is best: it directly addresses the dynamic physiology of pregnancy. It emphasizes flexibility and patient-specific adjustments rather than a fixed target, and it relies on multidisciplinary input to monitor maternal condition (weight, blood pressure, edema, labs) and fetal status, enabling timely changes as the pregnancy progresses. Why the other strategies are less suitable: keeping a fixed ultrafiltration target ignores the evolving needs of the mother and fetus, risking volume overload or dehydration. Stopping PD during pregnancy is not routinely warranted and would abandon a method that can be adjusted to maintain safety. Simply increasing dialysate glucose to drive ultrafiltration raises the glucose load, potentially causing maternal hyperglycemia and fetal exposure concerns, without addressing the overall balance of fluid and solute clearance. In short, the best approach is to continuously adjust ultrafiltration goals in PD and work closely with obstetrics to adapt to the changing demands of pregnancy.
