Polyhydramnios is associated with which scenarios, and what is a typical management approach?

• A. Fetal anomalies and maternal diabetes; monitor with ultrasound and manage underlying cause; may require amniotic fluid reduction if indicated
• B. Hypertension and preeclampsia; bed rest
• C. Placenta previa; immediate cesarean
• D. Fetal anemia; intrauterine transfusion

Answer: (A)

Polyhydramnios means there is too much amniotic fluid, and it most often points to situations where the fetus swallows less fluid or produces more urine. The two common scenarios are fetal anomalies that impair swallowing (such as certain GI or neural defects) and maternal diabetes, where maternal hyperglycemia leads to fetal hyperglycemia, increased fetal urine production, and excess fluid. Management is focused on evaluating and monitoring. Ultrasound helps quantify the fluid and also assesses fetal anatomy to identify swallow or other issues. If maternal diabetes is present, intensifying glucose control is important because better control can reduce fetal polyuria and fluid buildup. If the fluid is markedly excessive or causing risk (for example, preterm labor or cord compression), amniotic fluid reduction with amniocentesis may be considered to relieve pressure. Other scenarios listed don’t fit polyhydramnios as typical associations. Hypertension and preeclampsia are more commonly linked with reduced amniotic fluid. Placenta previa requires planning for delivery by cesarean rather than management of amniotic fluid. Fetal anemia is usually addressed when it leads to hydrops and may involve intrauterine transfusion, not the standard approach to polyhydramnios itself.
