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.
本回顾性研究旨在确定犬类使用离子型碘化造影剂后相关的血流动力学改变。回顾了49只接受计算机断层扫描麻醉犬的病例记录。获取心率（HR）和直接动脉压值。总体而言，37%的犬心率或收缩压较基线值变化≥20%。4只犬（8%）出现心动过速，2只犬（4%）出现心动过缓。8只犬（16%）出现高血压，2只犬（4%）出现低血压。相当一部分犬在全身麻醉下静脉注射离子型碘化造影剂后出现心率和血压变化。
