Evaluation of Central Venous Access with Accelerated Seldinger Technique Versus Modified Seldinger Technique

Area of Science:

• Medical Procedures
• Emergency Medicine
• Device Innovation

Background:

• Central vein catheter (CVC) placement is a common emergency department procedure.
• The modified Seldinger technique can be time-consuming due to numerous steps and equipment.
• Preassembled devices offer potential simplification and time reduction for CVC placement.

Purpose of the Study:

• To evaluate if combination central line devices and the accelerated Seldinger technique reduce CVC placement time.
• To assess if the accelerated Seldinger technique increases the ease of CVC placement.

Main Methods:

• A randomized crossover study in a simulation setting.
• Comparison of the accelerated Seldinger technique versus the modified Seldinger technique.
• Inclusion of emergency physicians, residents, physician assistants, and medical students as subjects.

Main Results:

• The accelerated Seldinger technique with combination devices was significantly faster (35% reduction in time, p=0.001).
• Ease of use increased by 7% (p=0.046) with the accelerated technique.
• No increase in errors was observed with the accelerated Seldinger technique.

Conclusions:

• The accelerated Seldinger technique using combination CVC devices is faster than the modified Seldinger technique.
• This technique also offers increased ease of use for CVC placement.
• The findings suggest a more efficient method for CVC insertion in simulated environments.
