      - almost immediate onset
    - - not used much now - only in severe cases
      - continuous IV infusion
      - monitoring via APTT (activated partial thromboplastin time - if too long reduce dose to avoid bleeding)
  - - - factor 8 inhibitor
      - monitoring via INR (based on PT/prothrombin time - aim for 2-3)
      - antidote = vit k
    - - considered in young people
      - expensive
      - no monitoring required
      - no antidote - hard to reverse if haemorrhage occurs
- - - - backflow

      - varicosities (often irreversible)
  - - - cardiac arrest
      - pul infarct
      - haemoptysis
      - pneumonia
    - - breathlessness
