What are considerations for PD in pregnant patients?

• A. PD can be used with careful monitoring; adjust ultrafiltration strategies and coordinate with obstetric care to balance maternal and fetal needs.
• B. PD is contraindicated in pregnancy.
• C. Only HD should be used in pregnancy.
• D. No special considerations.

Answer: (A)

In pregnancy, peritoneal dialysis is a viable option when carefully planned and monitored to protect both mother and fetus. The continuous, gentle nature of PD helps maintain stable fluid and electrolyte balance and avoids the rapid shifts in hemodynamics that can occur with intermittent dialysis, which is advantageous for placental perfusion and fetal well-being. The key is to tailor the ultrafiltration strategy as the pregnancy progresses—using smaller fill volumes, more frequent exchanges, and possibly shorter or adjusted dwells—to prevent maternal dehydration or fluid overload while ensuring adequate urine production and clearance.

Coordination with obstetric care is essential to monitor fetal growth, maternal blood pressure, and electrolyte status, and to address any PD-related risks such as peritonitis or catheter complications. Dialysate glucose levels may need adjustment, especially if the patient has diabetes, to avoid excessive maternal glucose exposure. Be aware that a growing uterus can affect intra-abdominal pressure and catheter function, so exchanges and dwell times may require modification. Overall, PD is not contraindicated in pregnancy; with careful planning and teamwork, it can safely meet both maternal and fetal needs.
