    Contaminated surgical gloves introduced starch powder into spinal needles, leading to particulate contamination during myelography. Proper sterile technique is crucial to prevent cerebrospinal fluid contamination.

    Area of Science:

    • Medical Devices
    • Materials Science
    • Analytical Chemistry

    Background:

    • Spinal needles are used for cerebrospinal fluid access during myelography.
    • Particulate contamination can pose risks during invasive procedures.

    Purpose of the Study:

    • To investigate potential sources of particulate contamination during myelography.
    • To identify contaminants introduced via spinal needles and associated materials.

    Main Methods:

    • Scanning electron microscopy (SEM) was used to examine spinal needle stylets.
    • Energy dispersive X-ray analysis (EDX) identified particle composition.
    • Millipore filters were used to capture particulates from injected solutions.

    Main Results:

    • Starch powder from non-washed surgical gloves contaminated the spinal needle stylet.
    • SEM and EDX identified starch, talc, glass, and plastic particles (5-10 microns).
    • Contaminants were transferred to a 0.2 micrometer filter during simulated injection.

    Conclusions:

    • Non-sterile surgical gloves are a significant source of particulate contamination.
    • Myelography procedures risk introducing diverse contaminants into the cerebrospinal fluid.
    • Strict adherence to sterile techniques is essential to prevent patient harm.
