Study Notes

Antepartum Hemorrhage (APH)

  • APH is vaginal bleeding after 20 weeks of gestation and before delivery.
  • It's a significant cause of maternal and fetal morbidity and mortality, requiring prompt evaluation and management.

Causes of Antepartum Hemorrhage

  • APH can be categorized into placental and non-placental causes.

Placental Causes

  • Placenta Previa:
    • The placenta implants in the lower uterine segment, partially or completely covering the cervical os.
    • Types: Marginal, Partial, Complete
    • Presentation: Painless vaginal bleeding, often bright red, common in later second or third trimester.
  • Placental Abruption (Abruptio Placentae):
    • Premature separation of a normally implanted placenta from the uterine wall.
    • Presentation: Painful vaginal bleeding.

Non-Placental Causes

  • Genital Tract Lesions:
    • Cervical ectropion, polyps, carcinoma, vaginal varices, or trauma.
  • Uterine Rupture:
    • A tear in the uterine wall, often associated with uterine surgery (e.g., C-section or myomectomy).
    • Presents with severe abdominal pain, shock, and fetal distress. Associated with uterine history of surgery.
  • Infections:
    • Cervicitis or vaginitis.
  • Coagulopathy:
    • Maternal bleeding disorders (e.g., thrombocytopenia, disseminated intravascular coagulation).
    • Uterine tenderness, rigidity, or frequent contractions.

Risk Factors for APH

  • Placenta Previa: Previous C-section, advanced maternal age, multiparity, uterine surgeries, smoking, substance use.
  • Placental Abruption: Hypertension (chronic or gestational), trauma, external cephalic version, premature rupture of membranes (PROM), smoking, cocaine use, previous abruption, low-lying placenta, multiple gestation, in vitro fertilization. History of hypertension, trauma, and external cephalic version increase risk.
  • Vasa Previa: Low-lying placenta, multiple gestation, in vitro fertilization.

Clinical Features

  • Placenta Previa: Painless, bright red bleeding, sudden onset, often recurrent, uterus non-tender, relaxed.
  • Placental Abruption: Painful, dark red bleeding, sudden onset, may be associated with trauma or hypertension, rigid, tender uterus with frequent contractions, fetal distress is common
  • Vasa Previa: Painless bleeding associated with rupture of membranes, severe fetal distress, may lead to fetal exsanguination.

Differential Diagnosis

  • Bloody show (labor), cervical or vaginal trauma, cervical ectropion or polyps, genital tract infections.

Diagnosis of Antepartum Hemorrhage

  • History: Onset, amount, character of bleeding, associated symptoms (pain, uterine contractions), risk factors (previous C-section, hypertension).
  • Physical Examination: Assess maternal vital signs, uterine tenderness, rigidity, fetal heart tones.

Investigations

  • Ultrasound: First-line imaging to identify placenta previa or abruption, assesses placental location, fetal viability, and amniotic fluid volume.
  • Laboratory Tests: Complete blood count (CBC) to assess for anemia or thrombocytopenia, coagulation profile to rule out coagulopathy or DIC, blood group and cross-match.
  • Fetal Monitoring: Non-stress test or biophysical profile for fetal well-being.

Management of Antepartum Hemorrhage

  • Initial Management: Stabilize mother (ABCs, IV access, fluid resuscitation), monitor fetus (continuous fetal heart rate monitoring), determine cause (ultrasonography).
  • Specific Management: Different approaches based on cause (mild/severe bleeding, stable/unstable mother/fetus, gestation).
    • Placenta Previa: Mild - observation, bed rest, corticosteroids if <34 weeks; Severe - emergency C-section.
    • Placental Abruption: Mild - observation, supportive care, corticosteroids if <34 weeks; Severe - immediate delivery (C-section).
    • Vasa Previa: Confirmed diagnosis before labor - elective C-section at 34-36 weeks, or emergency C-section for acute bleeding.
  • Uterine Rupture: Emergency laparotomy and C-section, repair of rupture or hysterectomy.

Complications of APH

  • Maternal: Hemorrhagic shock, DIC, increased risk of C-section, hysterectomy, death.
  • Fetal: Preterm delivery, IUGR, hypoxia, stillbirth, neonatal anemia.

Prognosis

  • Early diagnosis and timely intervention significantly improve outcomes.
  • Close monitoring and multidisciplinary care is crucial.

Prevention

  • Early identification and management of high-risk pregnancies, smoking cessation, proper antenatal care, use of corticosteroids for fetal lung maturity.
