Patient handout

Post-cardiac-arrest care — peripartum maternal arrest

PRODUCTION

1. Your condition

This handout is for post-cardiac-arrest care — peripartum maternal arrest. Your care team identified this based on: rosc after maternal cardiac arrest in pregnant patient (typically ≥20 wks ga) or within 48-72h post-partum (aha 2024 maternal arrest).

Other reasons your team may use this plan: sudden cv collapse during labor / cesarean / immediate post-partum — afe differential top of list (hui 2022 consensus); comatose pregnant patient post-rosc — ttm candidate; pregnancy not a contraindication (ttm2; aha 2024).

2. Your medications

Take these medications exactly as prescribed. Do not stop or change a dose without talking to your provider.

norepinephrine0.05-0.5 µg/kg/min titrate MAP ≥65 (≥70-75 if undelivered for uteroplacental flow)IVcontinuousSOAP-II PMID 20200382; first-line in pregnancy per AHA 2024 maternal arrest (no vasopressor contraindicated in pregnancy when arrest)
amiodarone300 mg IV bolus → 150 mg if recurrent → 1 mg/min × 6h → 0.5 mg/min × 18hIVcontinuous taperAHA 2020 ACLS Class IIb; pregnancy concern (fetal thyroid) but life-saving so used per AHA 2024 maternal arrest
magnesium sulfate1-2 g IV bolus + 1-2 g/h infusion (eclampsia loading 4-6 g IV bolus then 1-2 g/h)IVbolus + continuousAHA 2020 ACLS Class IIa for TdP; ACOG-WHO Class I for eclampsia seizure prophylaxis (Magpie PMID 12057549)
tranexamic acid1 g IV over 10 min within 3h of bleeding onset; repeat 1g if bleeding continuesIVone-time + repeatWOMAN trial PMID 28456510 — TXA reduces death from PPH if given <3h; CRASH-2 PMID 20554319
oxytocin10 U IM + 10-40 U in 1L NS infusionIV/IMcontinuous post-deliveryACOG Class I uterotonic first-line for atony PPH
propofol5-50 µg/kg/minIVcontinuous; titrate RASSPADIS 2018; pregnancy category B; propofol crosses placenta but standard ICU sedation post-delivery
warfarinAVOID during pregnancy (teratogenic 6-12 wks; fetal hemorrhage); switch to LMWH if AC neededPOAVOIDACOG + AHA 2024 — warfarin teratogenic and fetal bleeding risk; LMWH preferred during pregnancy
enoxaparin1 mg/kg SC BID (treatment); 40 mg SC daily (prophylaxis)SCBID/dailyACOG / RCOG / CHEST 2018 — LMWH first-line AC during pregnancy + breastfeeding

Plan: Peripartum maternal post-arrest phenotype — modified ACLS pharmacotherapy + obstetric resuscitation + AFE/PPCM/PE/hemorrhage etiology bundles (AHA 2024 maternal arrest + Hui 2022 AFE consensus)

3. When to call your provider

Contact your care team if any of the following happen:

  • ICD therapy delivered → urgent EP
  • EF declining despite the four foundational heart-failure medications → advanced HF + transplant
  • Subsequent pregnancy attempted with EF <50 → high-risk MFM + cards joint program

4. When to seek emergency care

Call 911 or go to the nearest emergency room right away if you have:

  • Failure to achieve ROSC within 4 minutes of arrest in pregnant patient with viable gestational age (>20 wks) — perimortem cesarean indicated immediately (AHA 2024 Class I)(life-threatening)
  • Sudden CV collapse + profound hypoxemia + DIC (fibrinogen <200, dropping platelets, rising D-dimer) during labor / cesarean / immediate post-partum — AFE classic triad (Hui 2022 international consensus)(life-threatening)
  • Hemodynamic collapse + RV strain on echo + risk factors (postpartum, cesarean, immobility) — massive PE with arrest; thrombolysis Class I despite peripartum bleeding risk if hemodynamically unstable (AHA 2020)(life-threatening)
  • Massive postpartum hemorrhage (>1500 mL) with arrest — atony, accreta, placental abruption; massive transfusion + uterotonics + IR / surgical intervention(life-threatening)
  • Generalized seizure with maternal arrest in setting of preeclampsia (HTN + proteinuria + new-onset seizure) — Mg loading + control of HTN per ACOG(life-threatening)

5. Follow-up

Cardiology follow-up at 1-2 weeks for PPCM EF surveillance; MFM follow-up for any pregnancy continuation; counseling re: future pregnancy risk (PPCM with EF <30 — strong recommendation against future pregnancy); contraception planning; mental health (postpartum + post-arrest PTSD risk very high); AVID-style ICD pathway only for definite cardiac arrhythmic etiology unrelated to reversible peripartum cause
