021915 second,third trimester Flashcards
congenital syphilis can cause
spontaneous abortion (first trimester) stillbirth non-immune hydrops preterm birth hepatomegaly ascites anemia, thrombocytopenia
cervical insufficiency
painless cervical shortening or dilation leading to pregnancy loss
no pain, asymptomatic
risk factors for fetal anomalies
chromosomal
genetic abnormalities
exposure to teratogens (hyperglycemia in diabetic, meds, physical stresses, environmental)
3rd trimester complications
preterm premature rupture of membranes preterm labor hemorrhage secondary to placental abnormalities intrauterine fetal demise intrauterine growth restriction macrosomia
preterm premature rupture of membranes
chorioamniotic membrane rupture before onset of labor in pregnancies at less than 37 wks of gestation
ferns on microscopy are diagnostic for
preterm premature rupture of membranes
ferns on microscopy are diagnostic for
preterm premature rupture of membranes
diagnosis of preterm labor
regular contractions resulting in cervical dilation
hemorrhage secondary to placental abnormalities
placenta previa
placenta accreta
placenta abruption
velamentous cord insertion
hemorrhage secondary to placental abnormalities
placenta previa
placenta accreta
placenta abruption
velamentous cord insertion
placenta previa
placenta located over or near internal cervical os
risk factors for placenta previa
smoking, advanced maternal age, multiple gestation, uterine anomalies, scarring from previous pregnancies
placenta accreta
implantation extends into basal zone of endometrium, causing increased difficulty of removing entire placenta during delivery
risk for hemorrhage and hysterectomy after delivery
placenta percreta
implantation extends into uterine serosa or adjacent organs
placenta percreta
implantation extends into uterine serosa or adjacent organs
