Stillbirth: Causes, Diagnosis, Management, and Complications
1. Definition:
Stillbirth refers to the death of a fetus in the womb after 20 weeks of pregnancy. It’s a common occurrence, affecting approximately 10-20% of pregnancies. The causes of stillbirth are diverse, ranging from maternal factors, fetal factors, or a combination of both.
2. Diagnosis:
2.1. Symptoms:
- Vaginal bleeding: Blood is usually dark brown, may be scant or heavy, and can be continuous or intermittent.
- Abdominal pain: Pain can be mild or severe, depending on the extent of bleeding and placental detachment.
- Breast tenderness subsiding
- Psychological changes: Feelings of sadness, anxiety, restlessness, etc.
2.2. Tests:
- Ultrasound: Ultrasound is the most reliable diagnostic tool for stillbirth. The doctor will assess if the fetus has a heartbeat and if the fetal size corresponds to the gestational age.
- Note:
- Accurate gestational age determination is crucial for reliable ultrasound results, especially in early pregnancies.
- The presence of a fetal heartbeat is a crucial indicator of stillbirth. However, it needs to be assessed in conjunction with other signs like fetal size, position, and amniotic fluid volume for accurate diagnosis.
- Blood tests:
- Beta-hCG: Decreases after 24-48 hours in cases of stillbirth.
- Progesterone: Levels are low in stillbirth.
- Amniocentesis: May be used to determine the cause of stillbirth.
2.3. Diagnostic Challenges:
- Small stillbirth: Difficulties in early detection and prenatal examination.
- Misdiagnosis with other conditions: Vaginal bleeding during pregnancy can have various causes, requiring differentiation from stillbirth, ectopic pregnancy, miscarriage, placenta previa, etc.
3. Complications:
3.1. Psychological Complications:
- Emotional Impact: Stillbirth can severely impact the emotional well-being of pregnant women, especially those who have been trying to conceive for a long time.
- Negative emotions: Sadness, anxiety, guilt, self-blame, depression, etc.
- Relationship impact: Stillbirth can affect relationships with partners, family, and social circles.
3.2. Health Complications:
- Infection: Stillbirth can lead to uterine infection, potentially endangering the mother’s health.
- Vaginal bleeding: The longer the stillbirth persists, the higher the risk of vaginal bleeding.
- Coagulation disorders: Prolonged stillbirth can cause coagulation disorders, increasing the risk of maternal mortality.
4. Management:
- Principle: Preference for vaginal delivery of the stillborn fetus, except in cases requiring surgical intervention to save the mother.
- Management methods:
- Medication:
- Misoprostol: Used to stimulate uterine contractions and expel the stillborn fetus.
- Note: Misoprostol dosage varies depending on fetal size.
- Small fetus: 1-2 tablets of 200 mcg.
- Large fetus: 1/4-1/8 tablet of 200 mcg.
- Close monitoring of uterine contractions and vaginal bleeding is necessary.
- Surgery:
- Dilation and curettage (D&C): Indicated for small stillbirths.
- Cesarean section: Indicated in cases of:
- Abnormal fetal presentation
- Placenta previa
- Conjoined twins
- Large fetus
- Follow-up: After management, close monitoring of vaginal bleeding, uterine contractions, and overall maternal health is essential.
5. Causes:
- Maternal factors:
- Medical conditions: Diabetes, high blood pressure, thyroid disorders, autoimmune diseases, etc.
- Lifestyle: Smoking, alcohol consumption, drug use, stress, malnutrition, etc.
- Age: Stillbirth is more prevalent in older mothers.
- Fetal factors:
- Congenital malformations: Severe congenital defects can cause stillbirth.
- Chromosomal abnormalities: Chromosomal abnormalities are the most common cause of stillbirth.
- Genetic disorders: Genetic disorders can affect fetal development.
- Other factors:
- Infections: Infections during pregnancy can cause stillbirth.
- Trauma: Abdominal trauma can cause stillbirth.
- Placental abruption: Premature placental detachment can cause stillbirth.
- Placenta previa: Placenta previa can cause vaginal bleeding and stillbirth.
- Ectopic pregnancy: A condition where a fertilized egg implants outside the uterus, often causing vaginal bleeding and severe abdominal pain.
6. Differentiating from other conditions:
- Stillbirth: Dark brown, foul-smelling blood.
- Ectopic pregnancy (GEU): Blood originates from the fallopian tube – vagina, continuous, and intermittent.
- Miscarriage: Heavy bleeding, often accompanied by severe abdominal pain.
7. Signs of Miscarriage:
- Ultrasound: Images showing placental detachment, with greater detachment indicating a poorer prognosis.
- Low placental detachment: Rapid bleeding.
- High placental detachment: Continuous bleeding.
- Amniotic fluid:
- Brown amniotic fluid: Indicates fetal demise within the womb, causing contamination of the amniotic fluid.
- Foul-smelling amniotic fluid: Indicates fetal demise within the womb, causing contamination of the amniotic fluid.
- Pear-shaped amniotic fluid: Caused by decreased amniotic sac elasticity.
8. Bleeding in the Third Trimester:
- Placenta previa: Heavy bleeding, painless.
- Stillbirth: Dark brown, foul-smelling blood.
- Placental abruption: Non-clotting blood, often accompanied by severe abdominal pain.
9. Note:
- Regular prenatal checkups are crucial for early detection of stillbirth and other pregnancy complications.
- Seek medical attention for any unusual symptoms during pregnancy.
- Do not self-medicate or attempt to manage stillbirth without a doctor’s supervision.
10. Prevention:
- Manage medical conditions effectively.
- Maintain a healthy lifestyle: Consume a balanced diet, engage in regular exercise, minimize stress.
- Avoid smoking, alcohol, and drug use.
- Attend prenatal appointments regularly and follow doctor’s instructions.
- Get vaccinated against sexually transmitted infections.
- Undergo reproductive health assessments before pregnancy.
11. Conclusion:
Stillbirth is a serious issue affecting the mother’s physical and mental well-being. Seeking medical help for prompt diagnosis and treatment is crucial. Prevention is key, and following a doctor’s advice can safeguard both the mother and the fetus’s health.
