Plain-English summary
A group of 49 dogs that were put under anesthesia for a CT scan experienced changes in heart rate and blood pressure after receiving an iodine-based contrast dye. About 37% of these dogs showed significant changes, with some becoming too fast (tachycardic) or too slow (bradycardic) in their heart rates, and others experiencing high (hypertensive) or low (hypotensive) blood pressure. These reactions highlight the importance of monitoring dogs closely during and after the use of this type of contrast media.

Abstract
This retrospective study was conducted to identify hemodynamic alterations associated with the administration of an ionic iodinated contrast media in dogs. Case records of 49 dogs that were anesthetized for computed tomography scanning were reviewed. Values for heart rate (HR) and direct arterial pressure were obtained. Overall, 37% of dogs had a ≥20% change in either HR or systolic arterial pressure from baseline values. Four dogs (8%) became tachycardic and two dogs (4%) became bradycardic. Eight dogs (16%) became hypertensive and two dogs (4%) became hypotensive. A significant proportion of dogs experienced changes in HR and blood pressure following IV administration of an ionic iodinated contrast media under general anesthesia.
