Cricoid pressure (CP) is a complex maneuver, often ineffective and potentially risky. Further research and improved training are needed to ensure its safety and efficacy in anesthesia.

Area of Science:

  • Anesthesiology
  • Airway Management

Background:

  • Cricoid pressure (CP) is a standard technique to prevent regurgitation during anesthesia induction.
  • Optimal application of CP is challenging due to anatomical and physiological complexities.

Purpose of the Study:

  • To review and evaluate existing studies on the application of cricoid pressure.
  • To examine anatomical, physiological, safety, and efficacy aspects of CP, including its impact on airway management.

Main Methods:

  • Systematic literature search of three medical databases (48 Hours, Medline, Reference Manager Update) up to October 1996.
  • Inclusion of studies on cricoid pressure, focusing on keywords, subject headings, and text entries.

Main Results:

  • No studies definitively prove the benefit of CP.

Related Experiment Videos

  • Evidence suggests CP is frequently ineffective and may increase risks of failed intubation and regurgitation.
  • Guidelines for optimal CP use in various situations are proposed.

    • Conclusions:

    • CP must demonstrate safety and effectiveness to remain standard practice.
    • Enhanced understanding of CP's benefits and limitations is crucial.
    • Improved training and guidelines for CP application are necessary for patient care.
