Study Notes
Prolonged Pregnancy
Postdate Pregnancy Risks
- Increased risk of stillbirth and fetal death
- Higher risk of meconium aspiration syndrome
- Increased risk of fetal distress and acidosis
- Placental insufficiency and fetal growth restriction
- Increased risk of instrumental delivery and cesarean section
Induction Methods
-
Cervical ripening agents:
- Prostaglandin E2 (PGE2)
- Misoprostol
- Oxytocin
-
Mechanical methods:
- Artificial rupture of membranes (AROM)
- Foley bulb induction
- Double balloon catheter
-
Oxytocin augmentation:
- Used to stimulate contractions
- Dose and frequency vary depending on individual case
Fetal Surveillance
-
Biophysical profile:
- Ultrasound assessment of fetal movement, tone, and breathing
- Non-stress test (NST) and contraction stress test (CST)
-
Fetal heart rate monitoring:
- Non-stress test (NST) and contraction stress test (CST)
-
Modified biophysical profile:
- Combination of NST and ultrasound assessment of fetal movement and tone
Pregnancy Beyond 42 Weeks
-
Pregnancy beyond 42 weeks:
- Associated with increased risk of fetal mortality and morbidity
- Increased risk of meconium aspiration syndrome and fetal distress
-
Pregnancy beyond 44 weeks:
- Higher risk of stillbirth and fetal death
Maternal Risks
-
Increased risk of:
- Prolonged labor and instrumental delivery
- Cesarean section
- Postpartum hemorrhage
- Infection and endometritis
-
Maternal mortality:
- Increased risk with prolonged pregnancy
Indication of Cesarean Section
-
Fetal distress:
- Non-reassuring fetal heart rate patterns
- Fetal scalp pH <7.20
-
Umbilical cord prolapse:
- Cord compression or prolapse
-
Placental abruption:
- Vaginal bleeding and fetal distress
-
Maternal indication:
- Previous uterine surgery or rupture
- Multiple gestation or fetal macrosomia
Prolonged Pregnancy
Risks
- Increased risk of stillbirth and fetal death
- Higher risk of meconium aspiration syndrome
- Increased risk of fetal distress and acidosis
- Placental insufficiency and fetal growth restriction
- Increased risk of instrumental delivery and cesarean section
- Increased risk of maternal mortality
- Prolonged labor and instrumental delivery
- Postpartum hemorrhage
- Infection and endometritis

Fetal Heart Rate Monitoring
- Non-stress test (NST) and contraction stress test (CST)
Modified Biophysical Profile
- Combination of NST and ultrasound assessment of fetal movement and tone
Pregnancy Beyond 42 Weeks
- Associated with increased risk of fetal mortality and morbidity
- Increased risk of meconium aspiration syndrome and fetal distress
- Higher risk of stillbirth and fetal death beyond 44 weeks
Indication of Cesarean Section
- Fetal distress
- Non-reassuring fetal heart rate patterns
- Fetal scalp pH
Induction of Labor
- Mechanical methods of induction include membrane sweep, artificial rupture of membranes (AROM), and Foley catheter insertion to dilate the cervix
- Pharmacological methods of induction include oxytocin to stimulate uterine contractions, prostaglandins to ripen the cervix and induce contractions, and misoprostol to ripen the cervix and induce contractions
- Combination methods involve using mechanical and pharmacological methods together to induce labor
Indications for Cesarean Section (CS)
Fetal Indications
- Fetal distress is an indication for CS, characterized by non-reassuring fetal heart rate or abnormal biophysical profile
- Macrosomia, estimated fetal weight > 4500g, is an indication for CS
- Abnormal fetal lie or presentation is an indication for CS
Maternal Indications
- Previous uterine surgery or CS is an indication for elective repeat CS
- Placenta previa or abruption is an indication for CS
- Multiple pregnancy is an indication for CS
Obstetric Indications
- Prolonged labor or failed induction is an indication for CS
- Cord prolapse is an indication for emergency CS
- Abnormal uterine activity or fetal heart rate is an indication for CS
Other Indications
- Maternal request or medical conditions such as hypertension or diabetes can be indications for CS
