Objective To study the application effect of warming pretreatment of iodinated contrast media in CT angiography. Methods From January 2023 to December 2023, 456 patients undergoing CT angiography in our department were selected and randomly divided into a constant temperature group (186 patients) and a room temperature group (179 patients). The room temperature group used non-warmed iodinated contrast media, while the constant temperature group warmed the iodinated contrast media to 37°C in a constant temperature incubator. The leakage phenomenon and occurrence of adverse events during the use of iodinated contrast media were compared between the two groups. Results there was no statistically significant difference in the frequency of contrast media leakage events between the two groups (P>0.05); 3 immediate adverse events occurred in the experimental group, and 10 immediate adverse events occurred in the conventional group. The frequency of immediate adverse events in the experimental group was significantly lower than that in the conventional group, with a statistically significant difference (P<0.05); no delayed adverse reactions occurred in patients in both groups. Conclusion Warming pretreatment of iodinated contrast media in CT angiography can achieve good results, reduce the occurrence of acute adverse reactions, and has important value.
