including to a few patients who were hypotensive), and the administration of higher than recommended doses of epinephrine, as well as occasional confusion about which concentrations of epinephrine should be injected in which manner (subcutaneously or intravenously). In our study, the most striking example of patient morbidity from non-recommended treatment occurred in the two patients who received doses of 1 mg of epinephrine in the absence of cardiopulmonary arrest, who both had cardiac complications. Fortunately, these complications were mild and transient and caused no serious morbidity," he said.

"We hope that after reading our study, radiologists, nurses, and technologists will agree that they must review the algorithms for treating contrast reactions on a regular basis (particularly issues related to diphenhydramine, oxygen, and epinephrine administration)," said Dr. Cohan. "In fact, we would suggest that such a review should probably occur at least twice a year. However, it is also consoling to know that even when patients have moderate or severe contrast reactions, the vast majority recover promptly and without any long term complications," he said.
