What are the infection control concerns with laryngoscopes? How can infection concerns be overcome?

  • Well recognised source of cross-contamination:
    • High-risk instruments, regularly contaminated with blood
    • Have been implicated as possible transmitters of CJD
  • Both the handle and blade can become contaminated during use
  • Single-use laryngoscope blades are encouraged:
    • Not been shown to be associated with an increased risk of complications
    • Use can be economical when sterilisation costs considered
  • If reusable laryngoscopes are used:
    • Blades should be sterilised by a regulated sterile supply department between uses
    • Handles should be disinfected or sterilised between uses
  • If video laryngoscopes are used:
    • Single-use blades are encouraged
    • Decontamination of reusable components must happen after each use in a standardised manner
  • Care should be taken to place used scopes in a designated receptacle after use to prevent contamination
