    • proteinuria BEFORE 20 weeks gestation
  21. What can occur as a complication of severe eclampsia?
    • HELLP syndrome:
    • Hemolysis
    • Eevated Liver enzymes
    • Low Platelets
  22. Symptoms of HELLP syndrome.
    • flu-like, 
    • nausea,
    • vomiting,
    • epigastric pain
  23. What are the 3 questions you should ask in a pregnant woman, especially with s/s of preeclampsia?
    1) Do you have a headache?

    2) Are you having any visual disturbances?

    3) Are you having any right upper quadrant or epigastric pain?
  24. S/S of preeclampsia.
    • Persistant hypertension
    • CNS symptoms:
    •     Headache
    •     Visual disturbances
    •     Hyperreflexia and clonus
    •     Seizure (1/400 of mild preeclamptics; 2%
    •     of severe)
    •     Stroke (rare)
    • Liver involvement manifested by:
    •     RUQ or epigastric pain
    •     Nausea and vomiting
    •     “I just don’t feel good”
    •     Dyspnea (related to pulmonary edema)
  25. Antihypertensive therapy is usually initiated
    when SBP is ≥______mmHg and/or DBP is ≥_______
    Target goal: SBP _______; DBP
    • 160
    • 105 to 110
    • 140-150
    • 90-100
  26. Delivery is recommended
    for any patient with preeclampsia at least __ weeks gestation
  27. If pt with preeclampsia is <37 weeks, what is the expected management?
    • Restricted activity  (although there is no evidence that supports that complete bedrest
    • improves outcome)
    • Daily fetal movement counts
    • Nonstress test and/or biophysical profile
    • Ultrasound to evaluate growth and AFI
    • Umbilical artery flow study (if growth is a concern)
    • Repeat laboratory evaluation once or twice weekly
    • Platelet count, serum creatinine, serum AST
    • Antenatal corticosteroids to promote fetal lung maturity in women less than 34 weeks gestation
  28. Care during a seizure.
    • Call for help
    • Ensure airway and breathing
    • Remain with patient
    • Prevent injury
    • Record time, length, type of seizure activity
  29. After seizure care.
    • IV access
    • Administer MgSO4
    • Assess maternal and fetal status
    • Suction if needed
    • Supplemental O2
    • Patient will be stabilized then deliver
  30. Hypertensive Disorders of Pregnancy: Fetal Risks.
    • Prematurity
    • Intrauterine
    • Growth Retardation
    • Low birth weight
    • Fetal intolerance to labor due to decreased placental perfusion
    • Stillbirth
  31. Why do pregnant women need to do the glucose test at 24-28 weeks?
    • In the second half of pregnancy, the
    • placental hormone hPL (human placental lactogen) causes maternal peripheral resistance to insulin
    • This ensures that there is glucose for the developing fetus
    • Mother metabolizes fat for energy and produces ketones as a result
  32. Gestational diabetes is diagnosed if two or more of the following values are met or exceeded:
    • Fasting =  95mg/dl
    • 1 hour = 180 mg/dl
    • 2 hour = 155 mg/dl
    • 3 hour = 140 mg/dl
  33. Goal for glucose monitioring.
    • Fastings < or = 95
    • 2 hour postprandials < or = 120
  34. Medication for diabetes management.
    • Glyburide (oral agent)
    • Insulin (injectable)
    • -Need for insulin will increase as pregnancy advances
  35. Effects of pregnancy on woman with heart disease.
    • Blood pressure drops during 2nd trimester in response to decreased systemic vascular resistance
    • 30% to 50% increase in intravascular                volume and cardiac output
    • Increase of heart rate by 15-20 bpm
    • Increased risk of thromboembolism
    • Dramatic volume shifts occur after delivery
    • Cardiac output may increase an additional 50% during labor
