Polyhydramnios - Coggle Diagram
Polyhydramnios
Management:
- Severe polyhydramnios is usually associated with fetal abnormality, if massive (e.g.: AFI >40), amnioreduction (drainage of excess fluid w needle), or NSAIDs.
- If fetal abnormality, refer to fetal medicine centre.
- TTTS best managed in fetal medicine centre w/ laser ablation of placental anastomoses.
- If preterm, assess risk of delivery w/ cervical scan and/or fibronectin assay, and consider steroids.
- If unstable or transverse lie at term, admit to hospital: CS if labour ensues w/ an abnormal lie
- NSAIDs cause fetal oliguria & can constrict the ductus arteriosus: close supervision is therefore indicated.
Complications:
-
- Of the cause (duodenal atresia associated with trisomy 21)
- Malpresentation at delivery because of increased room for fetus.
- Maternal discomfort because of abdominal distension.
-
Investigations:
- Exclude maternal diabetes w/ a GTT (glucose tolerance test)
- Ultrasound examination of fetus.
