High Risk PowerPoints (Week 7) Flashcards
biophysical risk factos
originates with mother or fetus
may affect development and functioning of both
genetic disorders, nutritional and general health status, and medical or obstetric related illness
kick count that needs to seek help
less than 3 / hr
crown rump length
crown to sacram
what is the most valuable diagnostic tool used in OB
US
BPP
physical exam of fetus, US, fluid and body/breathing tone, HR
good BPP scoer
greater than 8
modified BPP
non stress test and amniotic fluid volume
US look at
placenta, fetus, and amniotic fluid
oligo amniotic fluid
1-2cm
not much
poly amniotic fluid
over distended
>8com
amniocentesis
after 15 weeks
evaluate genetics = neural tube defects
moms who are Rh- need
rofolac
chorionic villus sampling
placental biopsy
maternal assay
multiple marker screen
- not diagnosis
first line of fetal testing
kick count
what do we want for nonstress test
no deceleration
look for variability
acceleration: 15/15, 10/10
gestational HTN
onset HTN without other findings after 20 weeks
BP >140/90 resolves after giving birth
can develop chronic HTN
preeclampsia
HTN Proteinuria
develops after 20 weeks
can also develop in PP
preeclampsia
- in absence of proteinuria
thrombocytopenia
impaired liver funciton
new onset renal insuff
pulmonary edema
new onset cerebral or visual disturbances
The little rabbit poked carrots violently
BP for severe preeclampsia
160/110
eclampsia
onset of seizure activity/coma in women with preeclampsia
can develop in PP
chronic HTN
HTN present before preg or before 20 weeks
preeclampsia common risk factor
multifetal gestation, HX of preeclampsia, chronic HTN, preexisting diabetes and/or thrombophilias, paternal factors
cause of preeclampsia
unknown
placental
preeclampsia
- increased endothelial cell perm
water/prtoein leaking out = edema
preeclampsia
- reduced kidney perfusion
decrease UO
preeclampsia
- decreased liver perfusion
epigastric pain = RUQ pain
preeclampsia
- neurological complicatpms
check DTR, HA
HELLP syndrome
hemolysis
elevated liver
low plateleth
how to diagnose protein uric
24hr urine is best
what might help prevent preeclampsia
low dose aspirin
when to go to ER
abdominal pain, significant headache, vaginal spotting, decrease fetal movement
