Improvement of central vein ultrasound-guided puncture success using a homemade needle guide—a simulation study
Authors' conclusion
In this simulation study, IP approach using a homemade needle guide for ultrasound-guided central vein puncture improved success rate at first pass, reduced the number of punctures/redirections and shortened the procedure duration compared to OOP and IP free-hand approaches.
Study context
- Population
- Operators performing simulated ultrasound-guided internal jugular, subclavian and femoral vein puncture270 punctures
- Participants
- 30 participants
- Comparison
- In-plane needle guided (IP-NG) vs in-plane free hand (IP-FH) vs out-of-plane free hand (OOP-FH)
- Primary endpoint
- Success at first pass
