5. Is there any contraindication to the use of oral contrast? | |
6. If a patient has had a prior reaction to IV contrast can we still use oral contrast? | |
The dilution of oral contrast with an agent like Omnipaque is such that the chance of a reaction is so small that we do not even get consent. Yet if we know the patient previously had a severe reaction to iodinated contrast then a barium based product is ideal. We use Readi-CAT 2 (2.1% barium sulfate suspension by E-Z-EM. We give 1 or 2 containers of 450 ml. The Readi-CAT is pre-mixed in individual use containers. | |
