Small for gestational age ( SGA) are babies who are smaller in size than normal for gestational age.
Fundal height, less than it should be for that stage of pregnancy, per McDonald's rule
U/S, to confirm AC or EFW<10% percentile for gestational age
Patient information What is SGA?
It's where bub's weight is below the 10th percentile for gestational age.
OK. But if bub is in mom's tummy, how do you weigh them?
We can measure fundal height, by feeling mom's tummy for the size of the womb. Or an ultrasound.
Constitutionall small, as a genetic trait
IUGR (intrauterine growth restriction)
Patient information What causes bub to be below the 10th percentile of weight?
So they can just be small because mom and dad is small, and they're going to be small. Or there can be some problem that's causing it.
U/S (serial growth scans), to monitor growth
Patient information How do you check for bub below 10th percentile for weight?
Repetitive ultrasounds, where we track growth, and can plot it on a chart to monitor it.
Addition of cornstarch-based products (e.g. Duocal powder) to the feedings
Endocrinologist, if Pt's do not catch up to growth by 2yo. GH (
growth hormone) therapy is sometimes required Gastroenterologist, to address reflux/
GERD, delayed gastric emptying/DGE Dietician, to address calorie deficit and FTT
Speech pathologist or OT, to address feeding issues, or sensory issues
Behaviorist, for feeding issues, usually for kids >2yo
Allergist, to Dx/rule out any food allergies, although this isn't necessarily more common in SGA
ENT, to Dx enlarged adenoids or tonsils, although this isn't necessarily more common in SGA
90% of babies born SGA catch up by 2yo
FTT (failure ot thrive)
Hypoglycemia → common in asymmetrical SGA because their larger brains burn calories at a faster rate than their usually limited fat stores hold
Low birth weight (<2.5kg, regardless of gestational age at time of birth)
IUGR (fundal height less than it should be for that stage of pregnancy)
LGA (antonym, large for gestational age)
