摘要

Under field conditions, the diagnosis of foal's diseases relies almost exclusively on the physical examination. As the signs of illness in the equine neonate are frequently vage and non-localizing, the diagnosis of diseases may be problematic. Thisoften causes misinterpretations and leads to ineffective prophylaxis and treatment. The purpose of this study was to evaluate the usefulness of diagnostic ultrasonography of the foal's abdomen under field conditions to provide an optimized technique andto describe the normal findings. Diagnostic ultrasonography of the abdomen was performed after obtaining clinical history and passsing the physical examination of 25 foals without signs of abdominal problems. The foals were scanned in a stable box, beingrestrained by three persons in semi-lateral recumbency. Usually, sedation was not necessary. The ventral abdominal wall was clipped, a generous amount of ultrasound coupling gel was applied and massaged on the skin surface. The ultrasonographic examination was carried out using a portable sector scanner ("Microimager 2000", Ausonics) with 5.0 and 7.5-MH_z transducers or a combined 5.0 and 7.5-MH_z transrectal linear-array scanner ("450 Enhanced", Pie Medical). Employing the 5.0-MH_z sector scanner first, the abdomen was explored from caudal to cranial in left and right semi-lateral recumbency. The 7,5-MH_z scanner was used to attain higher resolution of certain structures. The sector scanner turned out to be suitable under field conditions and adequate to examine the abdominal organs. The transrectal linear-array scanner also provided the most important informations, although it was difficult to maintain a good contact area of the scan head. By ultrasonography it was possible to identify the urinarybladder, kidneys, spleen, liver and part of the gastrointestinaltract. Thus, application of ultrasound could succesfully be performed on newborn foals under field conditions.
