The jobPregnancy status changes the differential, imaging, medications, destination, and team.

  1. Confirm pregnancy status and gestational/postpartum age without delaying resuscitation.
  2. Prioritize hemorrhage, ectopic pregnancy, severe hypertension/eclampsia, thromboembolism, sepsis, trauma, and cardiopulmonary disease.
  3. Use obstetric, anesthesia, neonatal, and transfer resources early; local destination protocols matter.

Pregnant and postpartum patients can present with the same emergencies as anyone else plus pregnancy-specific catastrophes.

The ED must stabilize first, establish gestational/postpartum context, and involve obstetric expertise early under local pathways.

Ruptured ectopic pregnancy Critical

Key: Pain/bleeding with positive pregnancy test and instability is a surgical emergency.

Severe preeclampsia / eclampsia Critical

Key: Severe hypertension, headache, visual symptoms, RUQ pain, dyspnea, seizure, or postpartum presentation needs immediate obstetric protocol.

Obstetric hemorrhage / placental abruption Critical

Key: Bleeding, pain, uterine tenderness, shock, or trauma requires resuscitation and obstetric escalation.

Pulmonary embolism / peripartum cardiomyopathy Critical

Key: Dyspnea, chest symptoms, syncope, hypoxia, or new heart-failure signs require urgent evaluation.

Hyperemesis, UTI, uncomplicated early-pregnancy symptoms Common

Key: Assess hydration, ketones, infection, fetal/obstetric context, and safety-net carefully.

Tick what your patient has — the banner updates as you go.

Gestational age, LMP, parity, postpartum interval, prior ectopic/cesarean

Bleeding, pain, contractions, fluid loss, fetal movement when relevant

Headache, visual symptoms, RUQ pain, dyspnea, VTE risk, trauma, medications

ABCs and shock assessment; blood pressure with correct cuff

Abdominal/uterine tenderness, bleeding estimate, pelvic examination only when appropriate

Neuro/respiratory/heart-failure signs; fetal assessment per gestation and local resources

Immediate

  • Pregnancy test, CBC/type and screen, focused ultrasound when available, ECG/glucose as indicated
  • Rh status and obstetric hemorrhage protocol according to local practice

Imaging

  • Use ultrasound first when suitable; do not withhold indicated maternal imaging for a life-threatening diagnosis
  • CTA/VQ/MRI selection follows local pregnancy pathways

Consultation

  • Early obstetric/anesthesia involvement; arrange transfer to appropriate maternal level of care when needed
Medication safety reminder

Use this as a first-pass prompt; verify all medications, doses, concentrations, contraindications, weight, pregnancy status, and local protocols before administration.

Check indication, allergy, route, renal/hepatic risk, interactions, monitoring, and local formulary.

Discharge

  • Only stable low-risk symptoms after obstetric assessment or explicit local follow-up pathway.

Admit / obstetric unit

  • Bleeding, hypertension, infection, hyperemesis with derangement, trauma, or uncertain maternal/fetal status.

Resuscitation / OR / transfer

  • Ectopic rupture, eclampsia, major hemorrhage, severe cardiopulmonary illness, or need for higher-level obstetric care.

Use objective reassessment and the local pathway.

Before the next decision · reassess and hand over

Use these learning prompts with the presentation’s pathway. They are not discharge criteria.

  1. Reassess: compare symptoms, observations and examination with the initial assessment and response to treatment.
  2. Warning signs for Pregnancy-Related Emergency:
    • Hypotension, syncope, severe abdominal pain, shoulder pain, or heavy bleeding
    • Severe hypertension, seizure, headache/visual change, RUQ pain
    • Dyspnea, hypoxia, chest pain, syncope, or unilateral leg swelling
    • Trauma, decreased fetal movement, fluid loss, or painful contractions
    • Postpartum symptoms—risk persists after delivery
  3. Reconsider: check unresolved findings and alternative explanations, including the pitfalls below.
  4. Escalate: communicate deterioration, uncertainty or needs beyond the current setting.
  5. Plan the transition: identify outstanding results, responsibility for follow-up, patient understanding and specific return advice.

Clinical Pearls

  • The best fetal resuscitation begins with maternal resuscitation.
  • Pregnancy and postpartum status must be visible in every handoff.

Pitfalls

  • Letting pregnancy delay maternal resuscitation or indicated imaging.
  • Treating postpartum headache, dyspnea, or hypertension as benign without an obstetric differential.

Escalation and access

Know the local route to urgent obstetric/gynecologic assessment and supported transfer. Clinical instability must guide the urgency while tests are pending.
