Area of Science:

  • Medical Devices
  • Infectious Diseases
  • Vascular Access

Background:

  • Central venous catheters (CVCs) are essential for long-term venous access.
  • Silicone elastomer catheters are widely used due to their biocompatibility and flexibility.
  • Assessing the safety and efficacy of CVCs is crucial for patient outcomes.

Purpose of the Study:

  • To evaluate the complication and infection rates of silicone elastomer central venous catheter insertions.
  • To determine the most effective methods for diagnosing catheter-related infections.
  • To assess the duration of service and cost-effectiveness of these catheters.

Main Methods:

  • Retrospective review of 157 consecutive silicone elastomer CVC insertions.
  • Analysis of complication rates, including insertion-related issues and catheter removal reasons.

  • Evaluation of diagnostic methods for catheter-related bacterial infection, comparing peripheral blood cultures, catheter blood cultures, and insertion site cultures.

    • Main Results:

    • A low insertion complication rate of 1.91% with no need for chest tube drainage.
    • A bona fide infection rate of 3.18% (1 infection per 2,544 patient days).
    • Catheter blood cultures and insertion site cultures were more predictive of contamination than peripheral blood cultures.

    Conclusions:

    • Silicone elastomer central venous catheters are safe and dependable for venous access.
    • The infection rate is low, supporting their use in clinical practice.
    • Outpatient insertion is feasible, offering a cost-effective alternative for patient care.
