Three-step method for ultrasound-guided central vein catheterization.

Area of Science:

• Medical Procedures
• Ultrasound Guidance
• Vascular Access

Background:

• The long-axis view and in-plane needle approach (LAX-IP) is preferred for ultrasound-guided central venous catheterization due to superior real-time imaging.
• However, the LAX-IP technique presents specific challenges and pitfalls.
• This study introduces and evaluates a novel, structured method to address these limitations.

Purpose of the Study:

• To describe a novel, step-by-step technique for ultrasound-guided central venous catheterization.
• To demonstrate the clinical utility and safety of this new approach.
• To overcome common difficulties encountered with the standard LAX-IP method.

Main Methods:

• A training program was conducted for all operators prior to the study.
• One hundred patients underwent central venous catheterization using the novel three-step technique.
• The method involves patient positioning, vein identification with ultrasound, use of a needle guide, and real-time imaging in two directions.

Main Results:

• The technique demonstrated a 100% success rate for catheterization.
• A median of only one puncture was required per patient.
• All procedures were completed within three punctures, with no reported complications.

Conclusions:

• The described three-step method relies on logical progression rather than operator spatial awareness.
• This technique mitigates issues related to two-dimensional ultrasound views and may offer enhanced safety.
• Further clinical trials are recommended to confirm the safety and efficacy of this approach.
