OB Clinical Flashcards
Vasospasm Endothelial cell activation Inc pressor response Prostaglandin and NO Endothelin Angiogenic and antiangiogenic proteins
Preeclampsia
Eclampsia =
Pre-Eclampsia + Convulsion/Coma
Difference bet preeclampsia and HTN
Proteinuria
Signs of impending Eclampsia
Headache
BOV
Epigastric pain
Pulmonary edema
HELLP
Hemolysis Elevated Liver enzyme Low Platelet Count
Vasospasm causes
Compromised uteroplacental perfusion
Most common cause of CP
Perinatal asphyxia
Fetal hypoxia
Drugs used for seizure in Eclampsia
Magnesium sulfate
Anti hypertensive of choice for HTN in pregnancy
Hydralazine
Ca ch blocker
Stable pre eclampsia medication
Methyldopa
Methyldopa side effect
Positive coombs test
Hemolytic anemia
Methyldopa
Procainamide
Hydralazine
Isoniazid
Positive
Drug induced lupus
anti-histone
anti hypertensive CI in pregnancy bec of fetal renal agenesis
ACEI
Magnesium toxicity
BP Decrease
UO decrease
Respiratory decrease
Patellar reflex absence
Worst prognosis in mag sul toxicity
Dec respiratory rate
Normal magnesium levels
4-7 meq/L
Mg >10 meq/L
Patellar reflex absent
Mg 12 meq/L
Respi paralysis and depression
Mag sul toxicity antidote
Cal gluconate
Cal chloride
Goal in eclampsia
Early termination of pregnancy
Proliferative trophoblast abnormality
Both syncytio and cytotrophoblast
GTD
Degeneration and partly hyperplastic changes in chorionic villi
Benign neoplasia of chorion with malig potential
H Mole
Hydropic degeneration
Villous edema
Absent villous blood vessel
Proliferation of trophoblastic epithelium
Absence of embryonic elements (fetus, amnion)
H Mole
1-2 mo amenorrhea
Nausea and vomiting
Uterine bleeding
Uterine growth
GTD
UTZ finding H Mole
Snowstorm pattern
multiple echoes
Most common mets by GTN
Lung
On x ray GTN mets may present as
cannon ball appearance
Marker for GTN
HCG
HCG exerts
thyrotropin like effect leading to elevated thyroxine levels and dec TSH
A large mole may be assoc with
Early onset pre eclampsia
Elevation of BHCG beyond 48 h after evacuation and the succeeding weeks, there may be
persistent trophoblastic disease
More tendency to be malig
High index of suspicion
Complete H mole
H Mole Tx
Suction curettage
Hysterectomy
Prophylactic single agent chemo: large uterus poor follow up
Chemotherapeutic drug used
Methotrexate
