Pregnancy Complications Flashcards
BP >140/90 after the 20th week of gestation. No pre-existing HTN, No proteinuria
Gestational HTN
Tx of Gestational HTN
alpha-methyldopa, labetalol, hydralyzine, nifedipine; deliver at 39weeks
HTN >140/90 and proteinuria after 20th week gestation to 6weeks post partum
Preeclampsia
Caused by abnormal placental spiral arteries, results in maternal endothelial dysfunction, vasoconstriction or hyperreflexia
Preeclampsia
Increase the incidence of preeclampsia
preexisiting HTN, diabetes, chronic renal disease, or autoimmune disorders
Complications associated with preeclampsia
placental abruption, coagulopathy, renal failure, uteroplacental insufficiency or eclampsia
Tx of Preeclampsia
alpha-methyldopa, labetalol, hydralyzine, nifedipine; IV magnesium sulfate to prevent seizure
Deliver at 34weeks if severe
Deliver at 37 weeks if mild
Preeclampsia + seizures
Eclampsia
Tx of eclampsia
antihyptertensives; Mg-sulfate and immediate delivery
HELLP syndrome
Hemolysis, Elevated liver enzymes, Low Platelets
Death of healthy infant 1month to 1year without cause
SIDS
Gestation pathway of Choriocarcinoma
Responds well to chemo
Germ cell pathway of Choriocarcinoma
Does not respond well to chemo
Premature separation of placenta from uterine wall before delivery of infant (bleeding can be concealed or apparent depending attachment site)
Placental abruption
Placenta attaches to myometrium without penetrating it
Placenta accreta
Placenta invades into myometrium
Placenta increta
Placenta penetrates through the myometrium and into uterine serosa
Placenta percreta
No separation of placenta after delivery, massive bleeding
Placenta accreta/increta/percreta
Attachment of placenta to lower uterine segments near the os, partially over the os, or completely over the os
Placenta previa
Miscarriage of fetus 20weeks before gestation
Spontaneous abortion
Most common site of ectopic pregnancy
Ampulla of fallopian tube
> 1.5-2L of amniotic fluid
Polyhydraminos
Oligohydraminos
esophageal/duodenal atresia, anencephaly, maternal diabetes, fetal anemia, multiple gestations
Causes of Polyhydraminos
Placental insufficiency, BL renal agenesis or posterior urethral valves in males
Causes of Oligohydraminos (if profound will lead to potter sequence)
secondary amenorrhea due to loss of basalis as a result of D&C
Asherman Syndrome
