Cardiac Tamponade — Management Pathway

Step-by-step decision

Choose step by step as prompted; reaching an endpoint gives the management recommendation. You can go back a step or restart anytime.

Full pathway

1. [Decision] Hemodynamically stable?
   Hemodynamically stable (echo shows effusion + RV collapse)? (Pericardial effusion restricting diastolic filling → obstructive shock (trauma/malignancy/infection/uremia/MI rupture/dissection/anticoagulation/iatrogenic). Beck's triad (hypotension + JVD + muffled heart sounds, complete in only 10–40%), pulsus paradoxus (inspiratory SBP drop >10 mmHg), tachycardia; ECG low voltage/electrical alternans. Echocardiography is key (effusion + diastolic RV collapse).)
   • Unstable (shock / tamponade signs) → Tamponade → emergency drainage
   • Stable (effusion without tamponade) → Effusion without tamponade · monitor
2. [End] Effusion without tamponade · monitor
   Treat the underlying cause, monitor closely (serial echo); have a drainage plan ready, avoid hypovolemia and use vasodilators with caution; drain if it deteriorates.
3. [End] Tamponade → emergency drainage
   Tamponade/instability: emergency pericardiocentesis/drainage (echo/fluoroscopy-guided) is the definitive treatment; trauma/hemorrhagic/purulent/recurrent → surgical pericardial window or thoracotomy. While preparing: cautious fluids to raise preload, avoid positive-pressure ventilation/intubation and vasodilators where possible, inotropes if needed; reverse anticoagulation.
