Exam 4 Preeclampsia Flashcards
The onset of HTN without proteinuria after week 20 of pregnancy
Gestational HTN
HTN is defined as a systolic BP greater than what?
140/90
Gestational HTN does not last longer than what?
Week 12 postpartum
When does gestational HTN usually resolve?
1st postpartum week
Pregnancy-specific condition in which HTN and proteinuria develop after 20 weeks of gestation in a woman who previously had neither
Preeclampsia
A vasospastic, systemic disorder that is easily characterized as mild or severe
Preeclampsia
When does preeclampsia resolve?
After the birth the fetus and expulsion of the placenta
Risk factors for preeclampsia
- Primigravida younger than 19 or older than 40
- Severe preeclampsia in previous pregnancy
- Family history of mother or sister with preeclampsia
- Paternal history of fathering a preeclamptic pregnancy in another woman
- African descent
- Multifetal gestation
- Maternal infection/inflammation
What preexisting medical or genetic conditions are risk factors for preeclampsia?
- Chronic HTN
- Renal dz
- Pregestational DM
- Connective tissue dz (lupus, RA)
- Thrombophilia
- Obesity
What is the best preeclampsia prevention method?
Early prenatal care and early detection
Mild preeclampsia BP
Greater than or equal to 140/90
Proteinuria for mild preeclampsia
Greater than or equal to 1+ on a dipstick
Urine output for mild preeclampsia
Greater than 25-30 mL/hr
Fetal effects of mild preeclampsia
Placental perfusion is reduced and intrauterine growth restriction
Severe preeclampsia BP
Greater than or equal to 160/110
Proteinuria for severe preeclampsia
Greater than or equal to 3+ on a dipstick
Urine output for severe preeclampsia
Less than 500 mL in a 24 hr period
HA with mild/sever preeclampsia
Mild: absent/transient
Severe: persistent/severe
Visual problems with severe preeclampsia
Blurred, photophobia
Pulmonary edema with mild/severe preeclampsia
Mild: absent
Severe: may be present
Irritability or changes in affect with mild/severe preeclampsia
Mild: transient
Severe: severe
What might be present with severe preeclampsia but not mild?
Epigastric pain, N/V, thrombocytopenia, impaired liver function
Fetal effects from severe preeclampsia
Decreased perfusion expressing as IUGR, abnormal fetal status on antepartum tests
The onset of seizure activity or coma in a woman with preeclampsia who has no history of preexisting patho
Eclampsia
Usually preceded by premonitory s/s, including persistent HA, blurred vision, severe epigastric or RUQ abdominal pain, and altered mental status
Eclampsia
What follows an eclampsia seizure?
Hypotension, muscular twitching, disorientation, amnesia
What do you monitor with eclamptic pts?
Urine output, lung sounds, DTRs, may have mag sulfate toxicity. You expect BP to be low, but really watch the respirations
A lab diagnosis for a variant of severe preeclampsia that involves hepatic dysfunction
HELLP Syndrome
HELLP Syndrome is characterized by what?
- Hemolysis (H)
- Elevated liver enzymes (EL)
- Low platelets
HELLP Syndrome usually develops when?
Antepartum period, progresses rapidly
Mag sulfate is continued after birth for how long?
12-24 hours
