* If persistent >6h apart

Recommended management:

Follow-up in 1 week

+ Consider steroids and Magnesium Sulfate if ≤ 34.6 weeks

** An abnormal DV in the absence of a pulsatile umbilical artery is very unlikely to reflect a risk of acidosis. Therefore, before 34 weeks the decision to delivery should be relied upon the CTG. Rule out cardiac dysfunction or malformation.

Recommendations:

Control every two weeks
Amniotic fluid (maximum vertical pocket) + estimated fetal weight or abdominal circumference + peak systolic velocity middle cerebral artery
