Background

  • Occurs in ~1 in 30,000 pregnancies[1]
  • Key differences from non-pregnant cardiac arrest:
    • Need to remove uterus from IVC
    • Non-cardiac cause of arrest is more likely
    • Perimortem C-section should be performed rapidly, and may save both fetus and mother

Clinical Features

  • Cardiopulmonary arrest in gravid female.

Differential Diagnosis

  • DDx - BEAT CHOPS
    • Bleeding / DIC
    • Embolism - coronary, pulmonary, amniotic fluid
    • Anesthetic complications
    • Tone (uTerine aTony)
    • Cardiac disease - MI, aortic dissection, cardiomyopathy
    • HTN, preeclampsia, eclampsia
    • Other - all typical H's and T's
    • Placental abruption, placental previa
    • Sepsis

Diagnosis

  • Clinical

Management

  • Standard ACLS management
    • Early defibrillation - use standard energy levels (safe for fetus in maternal arrest)
      • Anterior/Posterior pad placement is preferred
      • May use AP pads to pace as well
    • Give typical adult ACLS drugs/dosages
    • Aiway management / Ventilate with 100% FiO2
    • Monitor EtCO2
    • Ensure post-cardiac arrest care

Maternal Modifications

  • Manual left uterine displacement
    • Displaces uterus to pt's left, relieving aortocaval compression
    • May be of concern even if < 20 wks
    • Put hands on left side of gravid abdomen, and pull upwards towards ceiling and leftwards
    • Downward force will worse IVC compression
  • IVs above diaphragm - avoids IVC which may be compressed
  • Administer fluids and blood products
  • Anticipate difficult airway with high risk of aspiration
  • If pt receiving IV magnesium prearrest, stop mag and give arrest dose calcium
  • Continue CPR, positioning, de-fib, drugs, and fluids during and after C-section
  • Therapeutic hypothermia contraindicated if pt still intrapartum, but may be safe for postpartum cardiac arrest[2]

Disposition

  • Admit (if ROSC obtained)
