Ultrasound-Guided Right Internal Jugular Vein Cannulation by Operators of Different Experience: A Randomized, Pilot...

Area of Science:

• Medical Procedures
• Ultrasound Guidance
• Vascular Access

Background:

• Ultrasound-guided (US-guided) internal jugular vein (IJV) cannulation is standard practice.
• However, it presents a learning curve and potential risks for inexperienced practitioners.

Purpose of the Study:

• To compare the performance and complication rates of US-guided right IJV cannulation between experienced and inexperienced operators.

Main Methods:

• 108 procedures were randomized between expert (≥30 prior US-guided IJV cannulations) and non-expert operators.
• Key metrics included success rate, time, number of attempts, and complications.
• Statistical analysis used t-tests and chi-square/Fisher's-exact tests.

Main Results:

• Successful cannulation rates were high in both groups (100% expert vs. 94.44% non-expert).
• Experts demonstrated significantly faster cannulation times and fewer attempts.
• Higher, though not statistically significant, rates of carotid artery puncture and hematoma were observed in the non-expert group.

Conclusions:

• US-guided right IJV cannulation requires substantial experience, with approximately 30 procedures needed to achieve proficiency.
• Operator experience is crucial for optimizing efficiency and potentially minimizing complications.
