Summary

Patient positioning affects subclavian vein catheterization success. Retracting shoulders and turning the head can distort anatomy, complicating venous access. A neutral, flat position is recommended for easier subclavian vein cannulation.

Area of Science:

  • Anatomy
  • Medical Procedures
  • Radiology

Background:

  • The subclavian vein is a frequent site for venous access.
  • Percutaneous cannulation of this vein carries risks of complications and catheter malpositioning.

Purpose of the Study:

  • To investigate how different patient body positions influence subclavian vein anatomy during catheterization.
  • To identify optimal patient positioning for successful and safe subclavian vein cannulation.

Main Methods:

  • Gross anatomic dissection was performed.
  • Magnetic resonance imaging (MRI) was utilized to visualize anatomical changes.
  • The effects of various body positions on subclavian vein anatomy were analyzed.

Main Results:

Related Experiment Videos

  • Traditional patient positioning (shoulders retracted, head turned away) distorts subclavian vein anatomy.
  • This distortion increases the difficulty of successful catheter cannulation.
  • A neutral, flat patient position appears to facilitate cannulation.

Conclusions:

  • Current recommendations for patient positioning during subclavian vein catheterization may be suboptimal.
  • A neutral, flat position with the head and shoulders in a neutral stance is suggested to improve procedural success and reduce complications.
