are some of the problems that X-Ray Techs
the injection of contrast?
• Vein site selection - antecubital, wrist, or hand
a vein at that site
• Infiltration of the contrast (see the IV page under Procedures)
Here is a small sample from
lessons on vein site selection →
So, when you prepare to inject contrast -
♦ if you are injecting
into an already established IV site,
you need to assess that
IV site for the presence of
infiltration and the quality of that site,
♦ if you are choosing your own site, you need to select a
healthy and appropriately sized vein for your injection

vein site selection
will insure a successful injection of contrast on the first stick, without vein rupture and without infiltration.
CHOICE - ANTECUBITAL:
The antecubital site in the right or left arm is where 99.999...% of IV pushes should occur. The vein walls are typically
thickest at this site, and the veins are usually larger in diameter.
SECOND CHOICE - WRIST: Second only if you cannot locate
a healthy antecubital vein. And, if you use the wrist vein, select a more superior segment for a thicker vein wall.
vein walls are too thin. These veins rupture easily and infiltrate easily.
