Area of Science:

  • Medical Devices
  • Vascular Access
  • Minimally Invasive Procedures

Background:

  • Central venous catheterization is crucial for patient care but carries risks.
  • Existing methods can be complex and time-consuming, potentially leading to complications.

Purpose of the Study:

  • To develop and evaluate a new kit for safe and easy central vein cannula insertion.
  • To assess the efficacy and safety of the novel kit across different insertion techniques.

Main Methods:

  • A kit featuring a 22-gauge pilot needle with a Y-hub for Seldinger guidewire insertion was designed.
  • The kit was evaluated using three puncture methods: internal jugular, supraclavicular, and infraclavicular approaches.
  • Sixty patients underwent central venous catheterization using the kit, with each method applied to 20 patients.

Main Results:

  • The kit demonstrated a high success rate for central venous access.
  • Procedure time from puncture to catheter insertion was consistently under three minutes.
  • No serious complications were observed during the study.

Conclusions:

  • The devised kit offers a safe, easy, and efficient method for central vein cannula insertion.
  • The novel approach minimizes the need for needle removal and repeat punctures.
  • The kit shows promise for improving the safety and speed of central venous access procedures.
