Clinical Decision Under Constraint
Real-world maritime scenarios designed to sharpen your clinical decision-making at sea. Calm, operational, realistic.
Crushing Chest Pain, 14 Hours From Port
0230h. You are the sole physician on a 2,800-passenger cruise ship in the mid-Atlantic. A 52-year-old male crew member presents with crushing retrosternal chest pain radiating to the left arm, onset 45 minutes ago. Diaphoretic. GCS 15. 12-lead ECG shows ST elevation in V2–V4.
HR 104 • BP 148/92 • SpO2 96% on RA • RR 22 • Temp 36.9°C • NEWS2: 4
PMH: Hypertension (amlodipine 5mg), smoker 20 pack-years. No previous cardiac history. No allergies documented.
Nearest port with PCI capability: 14 hours at full speed. Helicopter range exceeded — nearest SAR base 680nm. Sea state 5 (rough). Satellite connection intermittent. Ship pharmacy: aspirin, clopidogrel, enoxaparin, morphine, GTN, tenecteplase available. No cardiologist onboard. TMAS line operational but 20-minute hold times reported this week.
You are facing a confirmed STEMI with no access to percutaneous coronary intervention for at least 14 hours. Fibrinolysis window is narrowing. The bridge is requesting your medevac recommendation. You have tenecteplase but have never administered it without a cardiologist present. TMAS is on hold.
What do you do? Consider: fibrinolysis risk-benefit, contraindication screening, bridge communication for potential diversion, and your documentation obligations.
Helicopter transfer not feasible. Ship-to-ship transfer considered but sea state prohibitive. Diversion would cost the company an estimated $800K+ and disrupt 2,800 passengers. Your clinical documentation will be reviewed by the company, flag state, and potentially port state authorities.
- Pre-hospital fibrinolysis protocols exist for exactly these resource-limited scenarios
- Document your decision-making process in real time, not retrospectively
- SBAR-M to bridge should include: clinical urgency level, time-sensitivity, and your specific operational request
- A well-documented clinical decision to treat is more defensible than a delayed transfer request
- Tenecteplase is weight-based, single bolus — review dosing before the emergency
