Does the IV catheter length matter?

April 28, 2017

After you successfully cannulate the vein, the most important factors determining if it stays in (I.E., doesn't extravasate/infiltrate/dislodge) are the length of the catheter and the distance of the vein from the surface.

Here's the bottom line:  

If the vein is <1 cm from the skin, standard IV length will probably be fine

If the vein is > 1 cm from the skin, you need a longer IV catheter.
