Area of Science:

  • Medical Devices and Technology
  • Clinical Procedures
  • Patient Safety

Background:

  • Limited access to ultrasound technology in many countries despite its benefits for central venous line placement.
  • Variability in operator experience impacts the success and safety of central venous catheterization.

Purpose of the Study:

  • To compare the difficulty and complication rates of central venous line placement with and without ultrasound guidance.
  • To evaluate the effect of operator training level on the outcomes of central line procedures.

Main Methods:

  • A randomized study involving 257 patients requiring central venous catheterization.
  • Patients were categorized by operator experience: expert (≥70 prior procedures) and non-expert/in-training.
  • Procedures were allocated to 'with ultrasound' or 'without ultrasound' groups.

Main Results:

  • Higher success rates were observed in expert and ultrasound-guided procedures compared to non-expert and non-ultrasound groups.
  • Overall complication incidence was 11.7%, with no significant difference between ultrasound and non-ultrasound groups.
  • The non-expert group showed a significant reduction in complications when using ultrasound (7.8% vs. 24%).

Conclusions:

  • Ultrasound guidance is crucial for reducing complications in central line placement by inexperienced operators.
  • Medical centers with trainees should prioritize ultrasound use for central line catheterization.
  • Training in ultrasound-guided procedures is essential for improving technique effectiveness and patient outcomes.
