## Clinical Presentation Analysis This patient presents with a **ruptured ectopic pregnancy** — the constellation of hemodynamic instability (hypotension, tachycardia), acute pain, free pelvic fluid, and **fetal heart activity in the adnexa** indicates an active, bleeding tubal pregnancy. ## Management Algorithm ```mermaid flowchart TD A[Ectopic pregnancy diagnosed]:::outcome --> B{Hemodynamically stable?}:::decision B -->|No - Rupture/shock| C[Emergency laparotomy]:::urgent B -->|Yes - Unruptured| D{Candidate for medical Rx?}:::decision D -->|Yes: β-hCG <5000, no rupture| E[Methotrexate IM]:::action D -->|No: high β-hCG, rupture risk| F[Surgical management]:::action C --> G[Salpingectomy ± repair]:::action E --> H[Serial β-hCG monitoring]:::action F --> H ``` ## Key Point: **Hemodynamic instability + evidence of rupture = emergency surgery.** This patient has: - Hypotension (100/60) and tachycardia (110/min) - Free pelvic fluid (hemorrhage) - Acute pain - Fetal heart activity (confirms viable ectopic, not threatened abortion) **Methotrexate is contraindicated** in ruptured ectopic pregnancy because: - It cannot arrest active hemorrhage - Delays definitive hemostasis - Increases mortality risk ## High-Yield: **Medical management (methotrexate) criteria:** - Hemodynamically **stable** - β-hCG typically <5000 IU/L (though up to 10,000 acceptable in selected cases) - Ectopic mass <3.5 cm - No free fluid or minimal fluid - No fetal heart activity - Reliable for follow-up This patient meets **none** of these criteria. ## Clinical Pearl: **Fetal heart activity in ectopic pregnancy** indicates a viable pregnancy with higher risk of rupture and hemorrhage — it is a relative contraindication to medical management and favors surgical approach even if hemodynamically stable.
