Study module: hyperacute stroke triage + reperfusion eligibility (IV thrombolysis + EVT)

Study-focused overview of hyperacute evaluation and reperfusion pathways (time last known well, imaging basics, thrombolysis vs thrombectomy concepts). Not a protocol; designed for exam-style understanding.

Suspected acute stroke is time-critical: activate local stroke alert/emergency response immediately and document last known well time. Proceed with urgent imaging and reperfusion eligibility evaluation per protocol.

Key takeaways

  • Explain 'last known well' and time-based decision constraints
  • Describe high-level imaging roles (CT/CTA/CTP vs MRI)
  • Differentiate indications/contraindications concepts for IV thrombolysis vs EVT
  • Identify nursing/ED priorities that preserve eligibility

Core timeline concepts

  • Last known well
  • Door-to-imaging
  • Door-to-needle / door-to-groin concepts

Imaging basics (high level)

  • Noncontrast CT: hemorrhage rule-out
  • CTA: large vessel occlusion
  • Perfusion: tissue at risk (where used)

Reperfusion modalities

  • IV thrombolysis (concept)
  • Endovascular thrombectomy (concept)

Common exclusion themes (conceptual)

  • Bleeding risk
  • Unknown onset
  • Recent procedures/anticoagulation context

Exam-style pearls

  • Don’t delay imaging
  • Glucose check
  • BP management per protocol
