Anesthesia providers can learn and retain correct cricoid pressure techniques. This study shows that with education and practice, the Sellick maneuver force can be accurately applied and remembered long-term.

Area of Science:

  • Anesthesiology
  • Patient Safety
  • Airway Management

Background:

  • Passive aspiration of gastric contents is a risk during anesthesia.
  • The Sellick maneuver, or cricoid pressure, is crucial for preventing aspiration.
  • Recommended cricoid pressure is 20 N when awake and 30-40 N when unconscious.

Purpose of the Study:

  • To assess if anesthesia providers and assistants can be taught and retain recommended cricoid pressure.
  • To evaluate the effectiveness of a training model for applying cricoid pressure.

Main Methods:

  • Fifty-three participants (MD faculty, residents, CRNAs, others) used a laryngotracheal model with a calibrated scale.
  • Cricoid force was measured before and after instruction, practice, and a 3-month follow-up.

Related Experiment Videos

  • Participants applied pressure simulating awake and unconscious patient scenarios.

    • Main Results:

    • All participants initially applied inadequate cricoid pressure.
    • Following instruction and practice, all participants learned and retained the recommended pressure levels.
    • The training model proved effective for teaching optimal cricoid force application.

    Conclusions:

    • Anesthesia providers and assistants can be effectively trained to apply correct cricoid pressure.
    • Knowledge and skill in applying the Sellick maneuver are retained for at least 3 months.
    • A practical model facilitates teaching and retention of optimal cricoid pressure.
