NURS 3334 Lecture Notes - Lecture 15: Neural Tube Defect, Fetal Viability, Gestational Sac
Document Summary
Major expected outcome can minimize adverse perinatal outcomes. Quad marker screening (serum) week gestation abnormality syndrome defects so and/or weeks (testing 15-18 weeks ideal for accuracy) age, maternal age, weight, race, whether insulin-dependent diabetic. Detection of adverse fetal condition or potential fetal compromise. Be prepared for an infant with a particular congenital condition. Screening for neural tube defects (ntd) high a positive test. Detects 80-85% of open ntd and open abdominal wall defects. Compared with (cid:498)normal(cid:499) values for each (cid:498)normal(cid:499) levels adjusted for: gestational. Low levels afp = risk for down"s. High levels afp = risk for neural tube. Higher than expected hcg and inhibin a = risk for down"s syndrome. Lower than expected for estriol = risk for down"s syndrome. Directional sound beams create images reflective of object density. Acog now recommends 1st trimester screening for everyone. Abdominal: (supine with pillow under one hip) (cid:498)basic(cid:499) level ) ultrasound screening: Assessment of fetal age estimation/ fetal growth:
