Purpose: To evaluate the incidence, severity, and risk factors of adverse drug reactions (ADR) to intravenous administration of nonionic iodinated contrast media in computed tomography (CT), and to determine the recurrence rate after premedication in patients with a previous history of ADR.
Materials and Methods: We prospectively recorded all ADR to intravenous CT contrast media in 32313 consecutive outpatients (54572 cases) who underwent contrast enhanced CT examinations. Clinical report forms and electronic medical records were reviewed to search for the incidence of ADR, treatment, and clinical outcome of patients. The risk factors of ADR to CT contrast media (age, sex, history of previous ADR, season) were evaluated using statistical analysis.
Results: Of the 54572 cases, a total of 191 (0.35%) had adverse reactions. Of the 191 cases, 157 (82%) were categorized as mild reactions, 29 (15%) were moderate, and 5 (3%) were severe. A total of 165 (86.4%) cases had acute adverse reactions (which occurred within 1 hour after administration), while 26 (13.6%) had delayed adverse reactions (occurred 1 hour after the administration). The rate of ADR was significantly higher in females [relative risk (RR) = 2.05, 95% confidence interval (CI) 1.53?2.75], patients under the age of 60 years (RR = 1.45, 95% CI 1.07?1.98), patients with a history of previous ADR (RR = 6.51, 95% CI 3.13?13.57), and in the spring season (RR = 1.44, 95% CI 1.07?1.95). The recurrence rate after premedication in patients with previous ADR to CT contrast media was 3.2% (8/247). No deaths occurred that were attributed to the contrast media.
Conclusion: The incidence of ADR to nonionic CT contrast media was 0.35%; most of which were mild reactions. Risk factors for ADR included female gender, an age of under 60 years, a history of previous ADR, and spring season.
