• Normal amniotic fluid volume varies and ↑ with gestational age.
  • The peak volume is 8001000 mL at 3637 weeks gestation.(MCQ)
  • In the late T2 or T3, amniotic fluid volume represents fetal urine output. .(MCQ)
  • Why is AFI is used as a measure of chronic uteroplacental function. .(MCQ)
    • If there is uteroplacental dysfunction and oxygenation to the fetus, the fetus preferentially shunts blood to the brain and heart, leaving the fetal kid- neys underperfused. This results in fetal urine output and, as a result, ↓ amniotic fluid.
  • The AFI is the sum of amniotic fluid measured in four quadrants of the uterus via the US. .(MCQ)
    • AFI > 5 cm: Adequate.
    • AFI < 5 cm: Abnormal (oligohydramnios).
    • AFI ³ 25 cm: Abnormal (polyhydramnios).
  • Oligohydramnios:
    • Most common cause: Ruptured membranes. .(MCQ)
    • Associated with intrauterine growth restriction 60% of the time.
    • Evaluate for genitourinary malformations.
  • Polyhydramnios: .(MCQ)
    • Fetal malformation (anencephaly, esophageal atresia).
    • Genetic disorders.
    • Maternal diabetes.
    • Multiple gestation.
    • Fetal anemia.
    • Viruses.
  • Polyhydramnios is associated with uterine overdistention, resulting in: .(MCQ)
    • Preterm labor
    • PROM
    • Fetal malposition
    • Uterine atony

Polyhydramnios and Oligohydramnios – USMLE Step 2
This is a review of the basic principles of diagnosis and treatment of Polyhydramnios and oligohydramnios for medical students preparing for Step 2 of the USMLE or Comlex or others learning clinical medicine.
What is Polyhydramnios
Polyhydramnois is the overabundance of amniotic fluid surrounding your baby in the uterus. Most of the time, although uncommon, polyhydramnios will resolve itself, but sometimes it can lead to other complications or be an indication of other problems. Your doctor or midwife will be able to detect polyhydramnios, and on a case-by-case situation be able to advise on how to manage it.
