2015 ACVIM Forum Research Abstract Program

Dogs that were euthanized for unrelated purposes and donated to the teaching hospital after death were enrolled. The dog's weight was recorded. Catheters were placed in the JV, CV and SV within 5 minutes of death in order to simulate CPR. Iodinated contrast material was injected (1 ml/5 kg) and flushed with saline while monitoring the cardiac silhouette using fluoroscopy. The time from starting the injection until the appearance of the contrast material in the right heart was recorded in seconds. Saline was flushed until the contrast material was seen in the heart or until a total of 20 ml has been injected. Injections of contrast material that took longer than 30 seconds to reach the heart were recorded as 30 seconds. The order of injection was randomized. Times between groups were compared using a Kruskal-Wallis test with a p-value of < 0.05 considered significant. Correlation between time and body weight was evaluated.
