[Disposable needles for epidural anaesthesia - basic requirements (author's transl)]

W Heinrichs, D Stratmann, J Meyer

    Der Anaesthesist
    |January 1, 1980
    PubMed
    Summary

    Manufacturers are increasingly marketing disposable epidural needles for single-shot and catheter techniques. Current materials fail to meet basic requirements, suggesting a lack of input from practicing anesthesiologists in the design process.

    Area of Science:

    • Anesthesiology
    • Medical Device Engineering
    • Materials Science

    Context:

    • Increasing market presence of disposable needles for epidural anesthesia.
    • Need for standardized and high-quality epidural needle components.
    • Variability in needle design and material performance across manufacturers.

    Purpose:

    • To outline the fundamental requirements for components used in disposable epidural needles.
    • To evaluate the suitability of current materials used in epidural needle assemblies.
    • To identify deficiencies in existing epidural needle designs based on clinical experience.

    Summary:

    • Analysis of disposable epidural needles reveals material failures in critical components.
    • Current manufacturing practices may not adequately incorporate feedback from anesthesiologists.
