OB Week 3: Assessment of High Risk Pregnancy
1. biophysical risk factors: blood incompatibility
nutritional status
alcohol/drug use
meds
gestational diabetes
preeclampsia
2. psychosocial risk factors: smoking
caffeine (IUGR)
alcohol/drugs
3. sociodemographic factors: low income
lack of prenatal care
age
marital status
4. environmental risk factors: chemicals
stress
1/4
, 5. amniotic fluid index: 10+ normal
<5 oligohydrominos (renal defects)
too much: polyhydrominos
6. biophysical profile testing: 0-2 asphyxia
3-7 abnormal, retest
8-10 normal
7. potter syndrome: oligohydraminos + renal agenesis
8. PG surfactant test: checks maturity of lungs
9. chronic villus sample testing: too much fluid in nape
10. kick count: fewer than 3 per hour call provider
should be 10+ an hour in third tri
11. two goals of biophysical assessment: identify fetus at risk for injury due to interrupted oxygen
identify appropriately oxygenated fetuses to avoid treatment
12. reasons for biophysical profile: diabetes
