[1] Hypertension in Pregnancy and Gestational Diabetes Mellitus Flashcards
Leading cause of maternal and fetal morbidity
HPN in Pregnancy
Most benign in spectrum of hypertensive disorders in pregnancy
Gestational Hypertension
Define: Gestational HPN
BP> 140/90 mmHg after 20 weeks in previously normotensive women
Is there proteinuria in Gestational HPN?
No
Criteria for Pre-eclampsia
with regards to Proteinuria
HPN + Proteinuria >= 300mg/24 hours
OR
Protein:Creatinine Ratio >= 0.3
OR
Dipstick 1 + Persistent
Criteria for Pre-eclampsia
alternate criteria without Proteinuria
HPN +
Thrombocytopenia: Platelets < 100,00/uL
Renal Insufficiency: Creatinine > 1.1mg/dL or double baseline
Liver Involvement: Serum Transaminase 2x normal
Cerebral Symptoms: Headache, visual disturbances, convulsions
Pulmonary Edema
Criteria for Proteinuria in Pre-Eclampsia
- Urinary protein spillage of 300mg or more in 24 hours
- Urinary protein concentration of 100mg/dL
- More in 2 random specimens taken 6 hours apart
[Exam Tip Card]
This is a marker for diagnosis of severe pre-eclampsia in HPN pregnant women
Growth restricted fetus
[Exam Tip Card]
Cases will be given and we are supposed to define the different terminologies in HPN
Go memorize them!
Define: Eclampsia
Presence of convulsions in a woman with pre-eclampsia, in which the convulsions cannot be attributed to any other cause
[Non-severe vs. Severe Pre-eclampsia]
Diastolic BP
N: 110 mmHg
[Non-severe vs. Severe Pre-eclampsia]
Diastolic BP
N: 160 mmHG
Indicators present in severe pre-eclampsia but absent in non-severe cases
- Headache
- Visual Disturbances
- Upper Abdominal Pain
- Oliguria
- Eclampsia
- Thrombocytopenia
- Fetal Growth Restriction
- Pulmonary Edema
A fetus is a prerequisite for pre-eclampsia
It is not, pregnancy does not require a fetus, it could be a hydatidiform mole
Describe the Endothelial dysfunction in the Pathogenesis of Pre-eclampsia
Normal Pregnancy: Prostaglandin to Thromboxane ratio is high, but in HPN the Thromboxane levels are increased while Prostaglandins are decreased
