Reacciones adversas a medios de contraste de uso endovenoso. Comparación entre medio iónico y no iónico / Adverse reactions to contrast media for intravenous use. A comparison between ionic and nonionic media

The purpose of this study was to show that the nonionic contrast media of low osmolarity are better tolerated than ionic media of high osmolarity, which to date are most frequently used in the authors hospital. We found that adverse reaction occurred in 80% of the group in which nonionic contrast medium was used. The authors conclude that nonionic, low osmolarity contrast media significantly reduce the frequency of adverse reactions and increase their safe use

Reacciones adversas a medios de contraste de alta osmalaridad. Estudio comparativo--prospectivo / Adverse reactions to high osmolarity contrast media. A comparative-prospective study

The purpose of this study was to verify and compare the different types of reactions to iodinated contrast media available at the Social Security Metropolitan Hospital Complex: Conray 60%, Vascoray and Uromiron. These are ionic, high osmolality compounds. The authors found that, in 400 patients not only the osmolality had an important role in the reactions observed, but that the intrinsic nature of the molecule of the contrast medium used was the determining factor
