Sci. 2001 2 1 71-74 JOURNAL OF Veterinary Science Application of pulsed Doppler ultrasound for the evaluation of small intestinal motility in dogs Yong-joo An Heechun Lee Dongwoo Chang Youngwon Lee1 Jai-ki Sung Mincheol Choi and Junghee Yoon Department of Radiology College of Veterinary Medicine Seoul National University Seoul 151-742 Korea 1 Department of Radiology College of Veterinary Medicine Chungnam National University Taejon 305-764 Korea The purpose of this study was to verify whether small intestinal peristalsis could be observed and quantitatively assessed using pulsed-Doppler ultrasound. Pulsed-Dop-pler ultrasound was used to evaluate small intestinal peristalsis after a meal in ten normal dogs and ten sedated dogs. The small intestinal peristalses were measured 0 1 3 6 9 12 and 24 hours after a 24-hour fast and after feeding. The number of small intestinal peristalsis were 0.133 min 0.100 min 0.033 min 0.167 min 0.070 min 0.067 min and 0.100 min in the fasted dogs and 1.667 min 0.933 min 1.133 min 1.234 min 1.933 min 1.533 min and 0.533 min in fed dogs respectively. In the dogs sedated with xylazine HCl the number of small intestinal peristalsis was significantly reduced p 0.01 . However in the dogs treated with ketamine HCl and acepromazine the number of small intestinal peristalsis remained unchanged. Therefore it can be concluded that pulsed-Doppler ultrasound allows graphic visualization of the intestinal movements which can be subjected to qualitative and quantitative analysis and may be suitable for a non-invasive study of small intestinal motility.
