In recent years as the use of interventional pain procedures has soared, so too has outside and internal scrutiny. This scrutiny includes agreater emphasis on weighing the risks and benefits of procedures, increased surveillance for adverse events, and cost containment strategies. In 2016, the first reports of gadolinium deposition in the central nervous system began to surface, though retention in other organ systems has been appreciated for over a decade. In this issue of Regional Anesthesia & Pain Medicine, Benzon et al. report a series of patients with document edhypersensitivity reactions to iodinated contrast medium who were inadvertently administered iodine-based contrast without adverse consequences. In this article, we discuss the epidemiology of contrast-mediated adverse effects, the mechanistic basis for hypersensitivity reactions, the risks and benefits of various approaches in the patient with a documented contrast hypersensitivity reaction, and risk mitigation strategies.
