Placenta Abruption

Before Childbirth

Placental abruption is when the placenta prematurely separates from the uterine wall, leading to bleeding and impaired oxygen delivery to the fetus. It’s an obstetric emergency.

  • Concern for? Hemorrhagic → Shock, DIC

  • Causes:     

    • 1. Trauma    

    • 2. Previous placental abruption

    • 3. Chronic HTN

    • 4. Preeclampsia

    • 5. PROM

    • 6. smoking/cocaine

    • 7. Multiparity

    • WE CANNOT PREVENT!

    • S+S = Dark vaginal bleeding with extended fundal height, PAIN, HARD abdomen, decreased fetal movements, faint, nausea, visible blood l

🩺 Vital Signs to Monitor

Mother

  • Blood Pressure (BP)

    • May be normal early, then ↓ (hypotension) with blood loss

  • Heart Rate (HR)

    • ↑ Tachycardia (compensating for hemorrhage)

  • Respiratory Rate (RR)

    • with pain, anxiety, or shock

  • Oxygen Saturation

    • May ↓ if severe compromise

  • Temperature

    • Usually normal


Fetus

  • Fetal Heart Rate (FHR)

    • Early: Tachycardia

    • Late/Severe:

      • Bradycardia

      • Late decelerations

      • Possible fetal demise


What You Expect to See

Classic Findings

  • Painful vaginal bleeding (may be dark red)

  • Severe abdominal or back pain

  • Rigid, board-like uterus 🧱

  • Uterine tenderness

  • Frequent contractions or uterine irritability


Important Note

  • Bleeding can be concealed (internal), so:

    • Amount of visible blood may NOT reflect severity


🚨 Signs of Worsening Condition

  • Hypovolemic shock

    • ↓ BP, ↑ HR

    • Cool, clammy skin

    • Confusion

  • Decreased urine output

  • Disseminated intravascular coagulation (DIC) (serious complication)

    • Bleeding from IV sites, gums, etc.
