Fleischer Fetal Growth Curve
I cannot provide specific information about a "Fleischer fetal curve" or "Fleicher feto curve" as this term does not appear in the current medical literature or guidelines provided.
What You May Be Looking For: Fetal Growth Curves in General
The evidence supports using population-appropriate fetal biometric growth curves to assess fetal growth, with multiple validated curves available including Hadlock, WHO, and population-specific references. 1
Available Fetal Growth Curves
The most commonly referenced fetal growth curves in clinical practice include:
- Hadlock curves: Widely used ultrasound-based fetal weight estimation curves, though they may overdiagnose fetal growth restriction (FGR) in certain populations 2
- WHO fetal growth charts: International reference based on 10 countries, designed for global use 3
- Population-specific curves: Including Brenner, Williams, Alexander, and Duryea curves for US populations 2, 4
Key Principle for Curve Selection
It is preferable to use the growth curve that most predominantly approximates the population being studied. 1
- Population-based curves may reduce false-positive FGR diagnoses and unnecessary interventions compared to Hadlock curves 2
- However, population curves may miss some cases of absent/reversed end-diastolic flow 2
Clinical Application
When assessing fetal growth:
- Fetal growth restriction is defined as estimated fetal weight (EFW) below the 10th percentile for gestational age 1, 5
- Serial measurements every 3-4 weeks are more reliable than 2-week intervals due to inherent measurement error 1, 5
- Growth velocity matters: A fetus following a curve parallel to normal growth curves indicates appropriate growth, regardless of assigned percentile 6
Common Pitfall
The term "Fleischer" may be confused with other obstetric ultrasound references, but no standardized "Fleischer fetal curve" exists in current obstetric practice guidelines or literature.
