A patient with a known allergy to iodinated contrast requires a CT scan. What is the most appropriate next step?
A patient with a known allergy to iodinated contrast requires a CT scan. What is the most appropriate next step?
- Pre-medicate with antihistamines and corticosteroids and proceed with the CT scan using iodinated contrast.
- Proceed with the CT scan, ensuring emergency resuscitation equipment is readily available.
- Administer a reduced dose of iodinated contrast to minimize the allergic reaction.
- Choose an alternative imaging modality that does not require iodinated contrast. (correct)
Why is it important to assess renal function (e.g., creatinine level) before administering iodinated IV contrast?
Why is it important to assess renal function (e.g., creatinine level) before administering iodinated IV contrast?
- To reduce the likelihood of contrast-induced nephropathy. (correct)
- To avoid allergic reactions to the contrast agent.
- To minimize the risk of vascular rupture.
- To prevent hepatic failure.

Flashcards
Safe Creatinine Level for IV Contrast
Safe Creatinine Level for IV Contrast
Creatinine ≤ 1.5 mg/dl and no acute kidney injury.
Iodinated IV Contrast Contraindications
Iodinated IV Contrast Contraindications
Contrast-induced nephropathy or allergy to iodinated contrast.
General I.V. Contrast Contraindications
General I.V. Contrast Contraindications
Hepatic failure, brain death, allergic reaction, hemorrhage, vascular rupture.
Study Notes
- There are two main contraindications for the administration of iodinated IV contrast: contrast induced nephropathy and allergy to iodinated contrast.
- Current policy suggests a creatinine of less than or equal to 1.5 mg/dl and no evidence of acute kidney injury for IV contrast administration.
- Further contraindications include:
- Hepatic failure
- Death brain
- Any allergic reaction
- Hemorrhage
- Vascular rupture
