Catheter tip position

Optimal central venous catheter tip location.

For catheters positioned to low or high, estimate the difference between the current and optimal placement.

Regular catheters:
The distal tip of jugular catheters should lie in the lower part of the superior vena cava.[1] For left-sides catheters, a tip in the upper right atrium has also been suggested.[1] However, the cardiac silhouettes are regarded as not reliable for this purpose, compared to using the carina as a landmark.[1] Hence, a catheter tip between 55 and 30 mm below the level of the carina is regarded as acceptable placement on anteroposterior X-rays.[2]

Central dialysis catheters:

  • The tip of nontunneled jugular hemodialysis catheters should be in the superior vena cava, and not in the right atrium.[3]
  • The tip of high-flow tunneled hemodialysis catheters should be within the right upper atrium.[3]
