Reaction to intraarterial ionic iodinated contrast medium administration in anesthetized horses.
Abstract: The purpose of this report was to evaluate the frequency and type of reactions to intraarterial iodinated contrast medium injection in horses. Ninety-seven received an intraarterial injection of ionic, iodinated contrast medium for computed tomographic assessment of the distal limb. Nine (9.0%) horses developed a reaction attributable to the contrast medium administration. Of those, 4/97 (4.0%) developed a skin response (three with urticaria, one with facial edema) within 20 min. Five (5.0%) developed elevation of heart rate and/or blood pressure immediately upon administration of the contrast medium. No horse developed a severe reaction such as shock, cardiac, or respiratory arrest. No treatment was necessary in any horse.

The research paper investigates the occurrence and characteristics of reactions to iodinated contrast medium injections in horses during CT scans of the lower limb.
Objective
The primary objective of this study was to explore the frequency and types of reactions experienced by horses following the administration of an intraarterial iodinated contrast medium injection.
Methodology
- A total of 97 horses were subjected to intraarterial iodinated contrast medium injections to enhance the visual quality of computed tomographic assessments of the distal limb.
Findings
- Approximately 9.0% of the horses (9 out of 97) developed reactions believed to be related to the contrast medium administration.
- Out of the horses that had reactions, 4.0% (4 out of 97) developed a skin response. These included three cases of urticaria (hives) and one case of facial swelling. These symptoms emerged within 20 minutes post-injection.
- An additional 5.0% (5 out of 97) encountered an elevated heart rate and/or increased blood pressure immediately after receiving the contrast medium.
- No severe reactions such as cardiac or respiratory arrest, or shock, were reported for any horse involved in the study.
- None of the horses required any further medical treatment for their reactions.
Implications
- The findings suggest a low incidence of reaction to iodinated contrast medium injections in horses, with no severe reactions observed.
- It indicates the administration of iodinated contrast medium for horse-related medical imaging is relatively safe.
- However, minor reactions like skin response and increase in heart rate and blood pressure were observed and should be acknowledged by practitioners during the administration of contrast.
