Real time information about direction and type of blood flow can be obtained with Doppler ultrasound. In the literature it was not found data obtained with this method from celiac and cranial mesenteric artery in cats. Moreover, sedation of the animal is occasionally necessary to obtain more information on any blood vessel using this method. The purpose of this study was to evaluate the quantitative aspects of spectral waves formed from blood flow of the celiac, cranial mesenteric, renal, external iliac, femoral, and aortic arteries in healthy cats, and to compare them with the same animals when subjected to midazolam, ketamine, and butorphanol sedation. We also measured the heart rate. Twenty healthy adult cats were evaluated. The values obtained for resistivity index and pulsatility index from the celiac artery were 0.62 ± 0.10 and 1.29 ± 0.55, and those from the mesenteric artery were 0.68 ± 0.09 and 1.37 ± 0.39, respectively. Although heart rate was higher in sedated animals, no significant statistical difference was found in case of other parameters, except celiac artery end diastolic velocity and time averaged mean velocity and iliac artery resistivity and pulsatility index. Thus, we provide the Doppler velocimetry parameter from celiac and mesenteric arteries and conclude that this protocol does not alter the values of Doppler ultrasound in the selected vessels, except the celiac and iliac arteries.
