Intravenous access: a comparison of two methods.

    Summary

    Plastic catheters offer more reliable venous access than winged needles. Catheters remained in the vein with less obstruction, ensuring a consistent circulatory route.

    Area of Science:

    • Vascular Access Devices
    • Medical Device Reliability
    • Intravenous Therapy

    Background:

    • Maintaining a reliable venous route is crucial for patient care.
    • Traditional winged needles may present challenges in prolonged venous access.
    • Advancements in catheter technology aim to improve venous access outcomes.

    Purpose of the Study:

    • To compare the reliability of a winged needle versus a plastic catheter for venous access.
    • To evaluate the incidence of complications such as vein dislodgement and obstruction.
    • To determine the preferred device for maintaining a continued venous route.

    Main Methods:

    • A comparative study was conducted using a winged needle (Abbott "Butterfly--23 INT") and a plastic catheter (Jelco Teflon "Catheter Placement Unit", 22 gauge).
    • Both devices were assessed for their ability to maintain a continued venous route to the circulation.
    • The incidence of total obstruction and device dislodgement was recorded during the study period.

    Main Results:

    • The plastic catheter remained within the vein in all tested cases.
    • The winged needle group experienced a significantly higher incidence of total obstruction.
    • The plastic catheter demonstrated superior reliability in maintaining an open venous route.

    Conclusions:

    • Plastic catheters provide a more reliable venous access route compared to winged needles.
    • For situations without an ongoing intravenous infusion, plastic catheters are recommended for consistent circulatory access.
    • The findings support the use of plastic catheters for improved venous access outcomes.
