This is an iatroX educational summary of named Canada sources, not an official guideline. It does not replace the complete source documents, local policy, specialist advice or clinical judgement. The evidence source is pan-Canadian, but formularies, funded access, referral routes, public-health directions and service availability remain provincial or territorial.

Source and scope

This summary is bounded to the recommendations, population and decisions covered by Guideline No. 414: Management of Pregnancy of Unknown Location and Tubal and Nontubal Ectopic Pregnancies. Apply it with the current provincial or territorial pathway where implementation differs.

Source-attributed clinical priorities

  • Treat pain, bleeding, syncope or hemodynamic compromise in a possible pregnancy as ectopic pregnancy until urgently assessed.
  • Use serial quantitative hCG and transvaginal ultrasound within a pregnancy-of-unknown-location pathway when diagnosis is not established.
  • Discuss expectant, medical and surgical miscarriage care based on stability, findings, preference and access, including Rh prophylaxis under current Canadian guidance.
  • A single hCG value cannot determine pregnancy location; symptoms, ultrasound and serial change must be integrated.

Practical assessment and management workflow

1
Assess hemodynamics, pain, bleeding, shoulder symptoms, gestation and ectopic risk.
2
Obtain quantitative hCG, blood group and transvaginal ultrasound through an early-pregnancy pathway.
3
For pregnancy of unknown location, arrange reliable serial testing and written return precautions.
4
Discuss expectant, medical and surgical options for confirmed loss or ectopic pregnancy when clinically appropriate.

Safety, red flags and urgent escalation

  • Shock, peritonism, syncope or severe unilateral pain requires emergency surgical assessment.
  • Do not give methotrexate until a viable intrauterine pregnancy and contraindications have been addressed.
  • Provide Rh immunoglobulin according to current Canadian and provincial policy.
