What are some risk factors that predispose to acute adverse contrast reactions?
- • Prior allergic-like reaction to contrast material. (Patients with a history of prior severe contrast reaction have an ≈5- to 6-fold increased risk of a future contrast reaction.)
- • History of severe allergies or reactions to other agents (food or medications), especially when to multiple agents.
- • History of asthma, bronchospasm, or atopy.
- • History of cardiac or renal disease.
