Multifetal gestation Flashcards
Monoamniotic twins are significant because they?
share a placenta, mortality is increased
What would change with the induction of monoamniotic twins?
they are induced early
What is the most significant cause of mortality with multifetal gestation>?
Preterm delivery
What is hydramnios?
too much amniotic fluid?
The uterine size is larger than expected for gestational age. What test and suspect would you have?
twins, ultrasound
What is the best way to determine the number of fetuses?
Ultrasound
You observe a lambda sign what is the significance of this?
twins non monoamniotic
What is a normal BMI for a normal wt woman with twins?
37 lbs
When do fetal kick counts begin?
30-32 weeks
What is a nonstress test?
fetal doppler monitor, that monitors fetal hr in response to fetal movement
What is an acceleration for Nonstress test?
15 beats/min above baseline for 15 secs
What is reactive NST?
2 or more acceleration over 20 mins
What is a nonreactive NST?
The baby could be asleep so no measure, warrants further assessment
no change in hr from baseline over 40 mins
Expected or desired fetal hr?
110-115 beats/min
What is a good indication of normal autonomic in a NST ?function
Reactivity
How long would an NST take before labeling as non-reactive?
40 mins
In a biophysical profile BPP what is included?
Fetal breathing movements fetal movements fetal tone amniotic fluid volume NST
When does a symmetric Fetal Growth Classification occur FGC?
early in gestation
Asymmetric FGR occurs when ? and what are common causes?
Later in gestation, smoking uteroplacental insufficiency
Tx goal of FGR is to maximize fetal growth maturity
True
What is macrosomia?
big baby 10lbs or >4500g
What are some risks to macrosomia fetus upon delivery
Brachial plexus injury
asphyxia
minor congenital abnormalities
respiratory problems
What is the biggest risk for macrosomia?
diabetes (gestation or preexisting)
What is the two step glucose test?
50g of oral glucose (fasting not required) measured 1 hr later
100g
