Study Notes
NST Findings and Interventions
- Reactive NST indicates a healthy fetal response with appropriate heart rate accelerations.
- Late decelerations require interventions such as vaginal examination, administering oxygen, and positioning the mother on her side, with calling the healthcare provider as a last resort.
Prenatal Labs and Procedures
- Initial prenatal visit should include a full blood count (CBC), rubella immunity check, and RPR/VDLR screening for syphilis.
- Amniocentesis is performed to collect amniotic fluid, which is essential for detecting genetic abnormalities.
Fetal Heart Rate Decelerations
- Fetal heart rate decelerations are classified into three types: late, early, and variable.
- Each type may indicate different underlying fetal conditions or issues during labor.
GTPAL System
- GTPAL stands for Gravida (total pregnancies), Term (term deliveries), Preterm (preterm deliveries), Abortions (spontaneous or elective), and Living children.
- For one patient with twins, GTPAL is recorded as 4-0-1-2-2.
Testing Timeline and Profiles
- Chorionic Villus Sampling (CVS) can be performed earlier in pregnancy compared to amniocentesis, specifically at 16 weeks gestation.
- A Biophysical Profile evaluates fetal health through measurements of fetal breathing, movement, and amniotic fluid volume, but does not determine the gender of the fetus or neck traversability.
CST Results
- A negative contraction stress test (CST) indicates no evidence of uteroplacental insufficiency, suggesting adequate oxygen supply to the fetus.
