Other PE-directed therapies (tPA failure/contraindication)

Relative contraindication & stabilized: may start with 50 mg alteplase.

Relative contraindication & actively dying: 50-100 mg alteplase.If no immediate access to epoprostenol or nitric oxide, use 5 mg nebulized nitroglycerine.If refractory may consider combination of nitric oxide plus epoprostenol.Epoprostenol or nitric oxide – whatever you can get fastest.Epinephrine is the preferred front-line agent, titrate for MAP > 65 mm.Don’t give fluid unless evidence of low filling pressure (e.g., small IVC or collapsed jugular veins).Fluid is rarely helpful (venous pressure generally already excessively high).benefit massive PE: resus ✅ fluid-conservative strategy ( more) Neutrophil/lymphocyte ratio (9.2 is worrisome 5.5-9.2 is a grey zone).īalancing risk vs.Contrast reflux into the inferior vena cava on CT scan.RV dilation on CT scan or echocardiography.RBBB or SI-QIII-TIII (both have OR of ~2).Hypotension caused by PE (SBP 40 mm for 15 minutes, requirement for vasopressors).

Risk stratification – bits to consider ✅ hemodynamic instability

Lactate (ideal, but not mission-critical).

⚠️ Order these ASAP, so they're ready when needed.
