Common Issues in Prenatal Care: Antepartum Fetal Surveillance.

Patients at increased risk of stillbirth should be assessed with antepartum fetal surveillance (AFS) tests at regular intervals. In general, AFS should begin at the gestational age at which delivery would be considered. Most surveillance tests are performed weekly, but more frequent testing should be considered for patients with high-risk conditions.

Common Issues in Prenatal Care: Fetal Growth Restriction.

Fetal growth restriction (FGR) is defined as an ultrasound (US)-determined estimated fetal weight or abdominal circumference less than the 10th percentile according to a population level reference curve. FGR affects up to 10% of pregnancies. Fetuses with FGR are at increased risk of intrauterine mortality and, postnatally, neonatal intraventricular hemorrhage, necrotizing enterocolitis, respiratory distress, hypoglycemia, and suboptimal neurologic, behavioral, and cognitive development.

Common Issues in Prenatal Care: Gestational Diabetes.

Two screening approaches are used to detect gestational diabetes, the 1-step and 2-step methods. The 1-step method is diagnostic and consists of a 75-g, 2-hour oral glucose tolerance test (OGTT). The 2-step method consists of a 50-g, 1-hour glucose challenge test, followed by a 100-g, 3-hr OGTT if initial test results are positive.

Common Issues in Prenatal Care: First Trimester Bleeding.

Vaginal bleeding in the first trimester is a common concern during pregnancy. The amount of bleeding and associated symptoms, such as nausea and vomiting, can be of prognostic value. Timely evaluation with vital signs, physical examination, laboratory tests (eg, Rh factor, hemoglobin and possibly progesterone levels), and pelvic ultrasound (US) can distinguish among viable pregnancy, nonviable pregnancy, intrauterine pregnancy (IUP) of uncertain viability, and pregnancy of unknown location.
