Dilution guide

Indication

Prehospital or in-hospital STEMI fibrinolysis.

Preparation

Reconstitute with supplied 10 mL sterile water.

Dilution

5 mg/mL

Rate

Single weight-based IV bolus over 10 sec: <60 kg 30 mg; 60–70 kg 35 mg; 70–80 kg 40 mg; 80–90 kg 45 mg; ≥90 kg 50 mg. Halve dose if ≥75 y (STREAM).

Monitoring

  • Neuro obs, BP
  • ECG q15 min post-lysis
  • Bleeding sites

Common errors

  • Overdose in elderly (must halve dose ≥75 y)
  • Concomitant full-dose antithrombotic

Pearls

  • Fibrin-specific — less systemic lysis than SK
  • Give with dual antiplatelet + enoxaparin (halved dose ≥75 y)
