Right atrial catheters for long-term venous access.

M E Beard, D C Heaton, J W Hamer

    The New Zealand Medical Journal
    |July 22, 1981
    PubMed
    Summary

    Hickman central venous catheters provide safe, long-term venous access for patients with blood disorders. Despite some complications like sepsis, these catheters are effective for neutropenic and immunosuppressed individuals.

    Area of Science:

    • Medical Devices
    • Vascular Access
    • Hematology

    Background:

    • Central venous catheters are essential for long-term venous access in patients with complex medical conditions.
    • Patients with blood disorders often require frequent or continuous venous access for treatment and monitoring.
    • Neutropenic and immunosuppressed patients are particularly vulnerable to infections and require careful management of venous access devices.

    Purpose of the Study:

    • To evaluate the safety and efficacy of Hickman central venous catheters in patients with blood disorders.
    • To determine the duration of catheter use and associated complications in this patient population.

    Main Methods:

    • Retrospective analysis of 32 patients with blood disorders who had Hickman central venous catheters placed.

    Related Experiment Videos

  • Data collection on catheter dwell time, reasons for removal, and incidence of complications.
  • Specific focus on catheter-related sepsis and its management.

    • Main Results:

    • Catheters were in situ for an average of 64 days.
    • Complications occurred in 7 patients, including 4 cases of catheter-related sepsis.
    • Catheters were removed in 20 patients (no longer needed or due to death) and remained in 5 patients at study end.

    Conclusions:

    • Hickman central venous catheters offer a safe method for achieving long-term venous access in patients with blood disorders.
    • These devices are suitable for use even in vulnerable neutropenic and immunosuppressed patients.
    • Careful monitoring is necessary to manage potential complications such as catheter-related sepsis.
