In cases of FGR requiring delivery due to maternal comorbid conditions, when is delivery recommended?

Delivery in cases of fetal growth restriction (FGR) due to maternal comorbid conditions is recommended primarily between 34 to 38 weeks of gestation to optimize neonatal outcomes while balancing the risks associated with preterm birth.

After 34 weeks, the lungs and other vital organs of the fetus are sufficiently developed, allowing for a better chance of a successful transition to life outside the womb. Additionally, in the presence of maternal comorbidities such as hypertension, diabetes, or any conditions that can compromise placental function, earlier delivery can mitigate risks to both the mother and the fetus.

Timing delivery closer to 38 weeks can further enhance respiratory maturity and reduce the chances of neonatal complications. However, this range is particularly tailored to the status of both maternal and fetal health at the time of assessment.

Delivering at earlier times, such as at 30-32 weeks, can pose risks associated with significant prematurity, including respiratory distress syndrome and other complications. Aiming for delivery before 34 weeks may not provide sufficient time for fetal development, while waiting until 39 weeks may pose additional maternal risks and may not be justified if the fetal condition is unstable. Therefore, aiming for delivery within this 34 to 38-week window strikes
