Complications of pregnancy Flashcards
“any time” complication
Rh isoimmunization
1st trimester complications (LMP date to 12 weeks)
Hyperemesis, bleeding, pregnancy loss
Molar Pregnancy (Gestational Trophoblastic Neoplasia)
2nd trimester complications (12-24 weeks)
Abnormal prenatal diagnostics, second trimester loss, bleeding
Placenta Previa (not usually a problem in the 2nd TM, but often diagnosed here)
Cervical Insufficiency
3rd trimester complications (24 weeks to term)
Many! But especially: Preterm labor, Preeclampsia, Chorioamnionitis, post dates pregnancy, complications of DM
Karyotype of a “complete mole”
46, XX, or XY
What is placenta previa and when to expect it
placental implantation over the cervix
suspect with painless vaginal bleeding occurs
vaginal delivery contraindicated
increased risk w prior c sections
placenta that has grown into the muscular part of the uterus
placenta accreta
Weakness of the cervix that results in cervical dilation/ effacement in the second trimester in the absence of contractions
cervical insufficiency / incompetent cervix
diagnosis / prognosis of cervical insufficiency
diagnosed w second trimester painless dilation
usually results in pregnancy loss
definition of preterm labor
contractions with cervical changes at 24-36 weeks gestation
Fetal fibronectin
good NEGATIVE predictive value of preterm labor
Tx for preterm labor
- bedrest
- oral Nifedipine
- iv magnesium sulfate
- progesterone supplementation for next pregnancy if hx of preterm
Triad of preeclampsia
Edema
Proteinuria
Hypertension
BP in mild vs severe preeclampsia
Mild = SBP 140-160
severe = SBP > 160
Proteinuria in mild vs severe preeclampsia
mild = 3-5g in 24 hr urine
severe = >5 g in 24 hr urine
HELLP
Hypertension Plus
Platelets <100,000 and/or
AST or ALT elevated and/or
pulmonary edema
Tx preeclampsia
Magnesium sulfate IV
