What is the deadly triad of pregnancy?
Hypertension, hemorrhage, infection
How do you diagnose gestational hypertension?
2) first time
3) No proteinuria
4) >2 BP readings, >4 hours apart
What is the only cure?
Delivery of the placenta
Pregnant
Healthy, nulliparous with no obvious risk factors
CBC, CMP (liver enzymes, creatinine), urine protein (24 hour or protein/creatinine ratio)
Incidence of Pre-eclampsia in the US?
5%
When is it commonly diagnosed?
3rd trimester
Who gets aspirin for prevention?
True or false: A headache is a reliable indicator of pre-eclampsia
False
Unreliable and nonspecific
When do you deliver?
1) >37 weeks
2) suspected placental abruption
3) > 34 weeks + (other features)
What is HELLP syndrome?
1) hemolysis
2) Elevated liver enzymes
3) Low platelets
What is the timeline?
to 12 weeks postpartum
How high should liver enzymes be to count towards this diagnosis?
two times normal
Risk factors for Pre-eclampsia?
Nulliparity, multifetal gestations, prior pre-eclampsia, chronic HTN, diabetes, thrombophilia, SLE, BMI>30, Antiphospholipid syndrome, AMA, kidney disease, OSA, assisted reproductive technology
1) 32-37 weeks
2) BP<150/100
3) Normal LFTs, platelets
4) No severe features
What features are no longer used to evaluate severe pre-eclampsia?
Hyperreflexia
transient hypertension of pregnancy
Common symptoms?
pulmonary edema, ARDS, MI, stroke, renal failure, retinal injury, coagulopathy

3) oligohydramnios
4) Persistent BPP 6/10 or less
Increased by 25%
Up to 50%
What 5 new onset features in combination with new onset hypertension would give this diagnosis?
1) Thrombocytopenia (platelets <100,000)
2) Renal insufficiency: Creatinine > 1.1 or doubling
3) Impaired liver function (increased LFTs)
4) Pulmonary edema
5) Cerebral or visual symptoms
