Chapter 54 Flashcards
Patient who has the potential for or is at an increased risk for an adverse maternal or fetal pregnancy outcome
High-risk
1st trimester testing looks for
the pattern of biochemical markers associated with plasma protein A [PAPP-A] and free beta-hCG
2nd trimester screening is performed with
maternal serum quad screen lab values and a targeted ultrasound
Quad screen consists of
AFP, hCG, UE3 (unconjugated estriol), and inhibin-A
Targeted ultrasound is
a detailed evaluation of all fetal anatomy
Maternal and fetal high risk factors
multiple gestation, drugs, advanced maternal age, abn. maternal labs, vag. bleeding, diabetes, HTN, preeclampsia, maternal systemic disease
Advanced maternal age refers to
A patient who will be 35 or older at the tie of delivery
Incidence of Downs syndrome ___ with age
increase
Risk of Downs @ 35
1 in 185
Risk of Downs @ 45
1 in 32
A condition in which excessive fluid accumulates within the fetal body cavities
Hydrops fetalis
Fluid surrounding the abdominal and pelvic organs
Ascites
Anasarca
Skin edema is massive encasing the majority of the body
Hydrops fetalis may results in
Ascites, anasarca, pericardial effusion, pleural effusion, placental edema, polyhydramnios
When the maternal clinical symptoms mimic the clinical features of the fetus such as edema, rapid weight gain, HTN, and mild proteinuria
Mirror syndrome/ ballantyne syndrome/ pseudotoxemia
