antenatal growth charts Flashcards
what is the role of antenatal growth charts
detect fetuses who are large/small for their dates
failure to detect abnormal growth can lead to…
increased mortality and morbidity
causes for small baby (estimated fetal weight <10th centile)
uteroplacental insufficiency
chromosomal abnormalities
foetal abnormalities
foetal infections
causes for large baby (estimated fetal weight >90th centile)
maternal DM - gestational diabetes, insulin-dependent diabetes
customised growth chart
customised to mother’s weight, parity, ethnicitiy
- better fetal outcomes and lower stillbirth rate
symphysis-fundal height against gestation and estimated fetal weight
any change in the curve (up/down) warrants obstetric review
