Keppler - 3 Flashcards
2 ways to assess fetal growth
fundal height
US (biometry)
fetal biometry includes (2)
head circumference
biparietal diameter
2 types of fetal growth abnormalities
macrosomia
intrauterine growth retardation (IUGR)
macrosomia includes (2)
LGA
S>D
macrosomia can be caused by (5)
GDM
constitutional (both parents are large)
excessive maternal wt gain
genetic syndromes
inaccurate dating
intrauterine growth retardation (IUGR) includes (2)
SGA
fetal growth restriction (FGR)
dx for macrosomia
fundal height
fetal US
which is more accurate: fundal height or US
US
4 tx for macrosomia
tx cause (ex GDM)
induction of labor
cesarean
genetic syndromes
risk of cesarean delivery
shoulder dystocia
causes of intrauterine fetal growth restriction (5)
placental insufficiency
infxn
genetic syndromes (aneuploidy)
inaccurate dating
constitutional
dx for fetal growth restriction
fundal height
fetal US
when is fetal growth restriction concerning
<10th %ile
what do umbilical cord dopplers tell us
if placenta is functioning properly
so that baby’s heart doesn’t have to work too hard
source of amniotic fluid
baby’s kidneys
too much amniotic fluid
polyhydraminos
too little amniotic fluid
oligohydraminos
why do we care about oligohydraminos
placental insufficiency → risk for fetal demise
major cause of polyhydraminos
GDM
how does the baby get rid of amniotic fluid
baby swallows it
why do we care about pollyhydraminos
preterm labor/rupture
cord prolapse
fetal malpresentation
fetal growth delay or excess is suggested by __
and is confirmed by __
abnormal fundal height
US → biometry
__ is critical to evaluating fetal growth abnormalities
accurate pregnancy dating
__
and __ are among mc causes of excessive fetal growth and excessive fluid
DM
GDM
important prevention of excessive fetal growth/fluid
aggressive glycemic control
__ is a common cause of fetal growth delay and oligohydraminos
placental insufficiency
management of oligohydraminos
close f.u
attention to delivery timing
