Study Notes
Definition and Risks of Post-Term Pregnancy
- Post-term pregnancy is defined as a pregnancy that extends beyond 42 weeks of gestation.
- Post-term pregnancy is considered a problem due to the increased risks of fetal and maternal complications.
Assessing Gestational Age
- If the date of the last menstrual period (LMP) is certain, the maturity of the pregnancy can be diagnosed accurately.
- Measurements up to the 14th week that provide a reliable indication of gestational age include:
- Crown-rump length (CRL)
- Biparietal diameter (BPD)
Assessing Fetal Maturity with Uncertain Menstrual History
- A reliable test to assess fetal maturity when the menstrual history is uncertain is a ultrasound scan.
Predicting Fetal Outcome
- Tests that can predict fetal outcome in post-term pregnancies include:
- Biophysical profile (BPP)
- Non-stress test (NST)
Complications of Post-Term Pregnancy
- A potential disadvantage of delayed onset of labor after term is an increased risk of:
- Fetal hypoxia
- Meconium aspiration syndrome
- Factors contributing to the increased risk of hypoxia in postmature cases include:
- Placental insufficiency
- Umbilical cord compression
- Hazards associated with postmature newborns include:
- Hypoglycemia
- Hypothermia
- Polycythemia
Counseling and Induction of Labor
- When counseling parents regarding waiting for labor to start naturally after 42 weeks, the woman should be made aware of:
- The risks of post-term pregnancy
- The importance of fetal monitoring
- Before making a decision to induce labor, the following should be checked:
- Cervical ripeness
- Fetal well-being
- Labor can be induced using:
- Oxytocin
- Artificial rupture of membranes (AROM)
Monitoring Labor and Fetal Condition
- Continuous electronic fetal monitoring (EFM) is required to monitor the progress of labor and the condition of the fetus.
Cesarean Section
- A cesarean section may be necessary during the first stage of labor if:
- Fetal distress is detected
- Labor is obstructed
- A labor induced post-term is more likely to require a cesarean section.
