Tracheal cuffs. A review and dynamic pressure study.

B E Crawley, D E Cross

    Anaesthesia
    |January 1, 1975
    PubMed
    Summary

    Prolonged tracheal intubation can cause complications. Large volume, low pressure cuffs are beneficial for airway pressure management and reducing tracheal injury during mechanical ventilation.

    Area of Science:

    • Medical Sciences
    • Anesthesiology
    • Critical Care Medicine

    Background:

    • Tracheal intubation is a common procedure in critical care.
    • Prolonged intubation can lead to tracheal complications.
    • The type of endotracheal tube cuff influences airway pressure and tissue damage.

    Purpose of the Study:

    • To review the sequelae of prolonged tracheal intubation.
    • To re-appraise the pressure dynamics of different endotracheal tube cuffs.
    • To confirm the benefits of large volume, low pressure (LVLP) cuffs.

    Main Methods:

    • Review of existing literature on tracheal intubation sequelae.
    • Analysis of dynamic pressure variations within the airway and cuffs.
    • Comparison of standard and floppy cuffed tubes.

    Main Results:

    • Large volume low pressure cuffs are confirmed to be advantageous.
    • Dynamic pressure variations in standard cuffs can exceed safe limits.
    • Floppy cuffs may offer better pressure distribution.

    Conclusions:

    • LVLP cuffs are recommended for minimizing tracheal injury during prolonged intubation.
    • Careful monitoring of cuff pressure is crucial.
    • Further research into cuff design and pressure dynamics is warranted.
