Flashcards in Obstetric Hemorrhage, Cardio, Pulmo Deck (42):
Happens when there is premature separation of a normally implanted placenta
Immediate event that can cause hemorrhage and subsequent abruptio placenta
This dangerous drug can cause vasoconstriction with resultant placental separation
Virchow's triad in placental abruption
Increased uterine tone
Diagnostic test for abruptio placenta where you put a blood sample in a test tube and positive if a clot forms within 6 minutes or forms and lyses within 30 minutes
Clot observation test
Most common obstetric cause of DIC
This intervention can be diagnostic and therapeutic in abruptio placenta
What is the boundary threshold for a low lying placenta?
Most common pathophysiology of placenta previa
Defective decidual vascularization
Management of placenta accreta
Classical CS, hysterectomy
Septic abortion and chorioamnionitis are associated with what coagulation pathway?
Intrinsic pathway (endothelial damage)
Abruptio, amniotic fluid embolism, retained dead fetus and saline induced abortion is associated with what coagulation pathway?
Syndrome characterized by widespread systemic activation of coagulation
The combination of nifedipine snd what other tocolytic agent can cause dangerous neuromuscular blockade?
Only well accepted risk factor of gestational hypertension
Classic presentation of placenta previa
Painless vaginal bleeding
Management of placenta previa is the placental edge is >2cm from os
Trial of labor
Management of placenta previa is the placental edge is <2cm from os
Vaginal delivery if possible
Classification of placenta accreta if it invades the myometrium
Classification of placenta accreta if it penetrates the myometrium and through the serosa
2 most important risk factors in placenta accreta
Hypertension without proteinuria occurring after 20 weeks AOG and BP returns to normal levels 12 weeks postpartum
BP 140/90 prior to pregnancy or before 20 weeks AOG and persists 12 weeks postpartum
What is the underlying etiology of proteinuria is seen with preeclampsia?
Increased capillary permeability
Renal change that occur in gestational hypertension
Mechanism in preeclampsia is placental implantation with replacement of ________ endothelium with trophoblasts
Prevention of preeclampsia syndrome
High dose calcium
Low dose aspirin
Management of severe preeclampsia if >34 weeks
Management of severe preeclampsia if <23 weeks
Management of severe preeclampsia if 23-32 weeks
Anti HTN if needed
Deliver at 32-34 weeks
Known fetal side effect of hydralazine
Drug of choice for severe hypertension in pregnancy
Drug of choice for gestational/chronic hypertension in pregnancy
Side effect of labetalol
Fetal growth restriction
What is the target magnesium level in eclampsia prophylaxis?
Drug of choice for prevention of convulsions in severe preeclampsia
Preferred mode of delivery for cardiovascular disorders
For patients with congenital heart disease, what is the most common adverse event encountered in pregnancy?
Most common etiology of CAP in pregnancy
Most frequent complication of pneumonia in pregnancy
Initial monotherapy for CAP
