SGA and FGR Flashcards
(10 cards)
define SGA
a baby born below the 10th centile of weight, categorised into constitutionally normal fetuses with non-placenta medicated growth restriction or placenta-medicated growth restriction
describe constitutionally normal
normal birth weight less than 10th percentile because of factors such as
maternal height, weight, ethnicity, parity a
and in these infants there is no increased risk of perinatal mortality or morbidity
define FGR
a baby that has not reached its growth potential
define early FGR
growth restriction prior to 32 weeks often associated with placental issues, chromosomal abnormalities or maternal disease
define late FGR
growth restriction after 32 weeks often due to less specific placental factors
define static growth by serial SFHs
a trajectory which is less than the slope of the curve indicated by the 10th centile line over the same gestational age interval
define static growth by serial EFW
trajectory between scan measurements which is slower than the slop of the 3rd centile line on the customised chart over the same gestational age interval
how do we identify risk factors, monitor growth and manage a diagnosis
booking: risk factors, health promotion of nutritional intake
referral for smoking, alcohol and substance misuse
early referral to fetal medicine if concern
personalised grwoth chart
accurate SFH measurement and referral for USS
individualised pathways under consultant-led care for reccurent USS and monitoring causes of FGR
monitor FM
assessment of growth and timely delivery if dopplers/growth/FM decline
discuss IOL vs CS early
SGA/FGR in labour
determine risk (compromised = less reserves = unable to withstand labour
CTG
preparing for potential resuscitation and paed review
short and long term complications of SGA/FGR
potential resuscitation
NNU admission
hypoglycaemia
hypothermia
poor feeding, lack of energy
increased chance of jaundice
long term physical, developmental and psychological disabilities
