Types of Contrast Infusion

• Direct IV Push
• This will be the primary method you use as a
  technologist. It can also be called a bolus
  injection.
• Drip Infusion
• Used when you want to administer contrast over a
  period of time. Some MR contrast agents use this
  method.

• Piggy back
• For us, piggy backing would be to use an existing
  port for the injection.
• To do this safely, you have to determine the
  patency of the existing line and what is already
  being administered through it.
• Ringers, D5W, and normal saline are typically
  considered safe to inject with.
• NEVER inject with blood products or other
  medications.

• As you can see, the needle should enter at a 15
  degree angle to the skin. The easiest way to get
  the angle is to run the needle over your
  thumb.
• Larger patients may require a steeper angle to
  access the vein.
