Study Notes
Prolonged Pregnancy
-
Prolonged pregnancy is defined as pregnancy extending beyond 40 weeks of gestation
-
10% of pregnancies are prolonged
-
Accurate first trimester dating scan is essential for diagnosis
Definitions
- Post-date pregnancy: Pregnancy lasting beyond 40 weeks
- Post-term pregnancy: Pregnancy lasting beyond 42 weeks
Risks of Post-Term Pregnancy
- Increased risk of stillbirth and neonatal death (two-fold increase after 42 weeks)
- Increased risk of macrosomia (larger than average baby)
- Increased risk of fetal distress during labor
- Increased risk of meconium aspiration syndrome
- Increased risk of needing operative delivery (e.g., C-section)
Management
- Antenatal visits (40 weeks): Membrane sweeping is recommended to potentially reduce need for induction of labor
-
After 40 weeks:
- Revise LMP (last menstrual period) and early dating scan for accurate diagnosis
- Assess fetal movement and listen for fetal heart sounds
- Monitor amniotic fluid volume via ultrasound (indicator of fetal well-being)
-
Confirmed fetal well-being:
- Induction of labor is planned at 41 weeks + 3 days if no other indications for Cesarean section.
- Patient should report to hospital immediately if fetal movement decreases
- VBAC (Vaginal Birth After Cesarean): Patients planned for VBAC who pass their due date may be candidates for a Cesarean section
