Abstract:Objective: To summarize the clinical characteristics and regularity of adverse drug reactions (ADRs) induced by the following 5 kinds of non-ionic iodine contrast agents: iohexol, iopromide, iopamidol, ioversol and iodixanol, and provide references for reducing clinically medication-related risks. Methods: Case reports of ADRs induced by 5 kinds of non-ionic iodine contrast agents mentioned above were collected from China National Knowledge Infrastructure (CNKI), and analyzed statistically. Results: Among all of the ADRs induced by the 5 kinds of non-ionic iodine contrast agents, severe allergic reactions (50.45%) accounted for the majority. Most of the ADRs happened within 10min. Among these 111 ADRs, 36 ones (32.4%) had hypersensitive test in advance, and 6 ones (5.4%) had ever used iodine contrast agents, but allergic reaction happened as well. Conclusion: Before using non-ionic iodine contrast agents, investigating patients’ allergy history in advance as well as observing their response during and after medication process may be more significant than conducting iodine allergy test. For the patients with an allergy history of iodine contrast agents, pretreatment may be a good advice.
