Prevention of contrast medium reaction for CT with IV contrast:
Pre-medication
Indication
Before a contrast CT of a patient with known allergic-like or unknown-type of contrast reaction to the same class of contrast medium (such as iodinated), the American College of of Radiology recommends premedication.
Asthma, atopy, and drug or food allergy have been regarded as generally not conferring enough risk to motivate glucocorticiod premedication.[1]
Medication
Preferably a glucocorticoid, preferably starting 12 or 13 hours before contrast administration.[2]
In emergent situations in adults and children over the age of 6, Swedish guidelines recommend the following pre-medication:[3]
- IV hydrokortisone, 200mg, immediately and then every 4 hours until the CT is done.
- Peroral desloratadine, 10 mg, 1 hour before IV contrast injection, if possible.
Other measures
Swedish guidelines recommend:[3]
- Having an adrenaline shot available in case of contrast medium reaction
- Switching to other contrast formula, although cross-reaction can still occur.
- Presence of an anesthesiologist if known severe reaction previously.
- Observation and remaining intravenous access at least 30 minutes after injection.
