The patterns of dispersion and drainage of a low viscosity, oil-based contrast medium within the peritoneal cavity were examined in 12 normal dogs. Intraperitoneal injection of contrast medium was cranial or caudal and drainage was by the sump-Penrose or open peritoneal method. Radiographs were made over a 96 hour period, before and after peritoneal drainage was established. Each dog was euthanatized and necropsied. The contrast medium was dispersed throughout the peritoneal cavity 15 to 30 minutes after cranial injection and 1 to 2 hours after caudal injection. Most of the contrast medium drained within 6 hours after open peritoneal drainage and within 24 to 48 hours after sump-Penrose drainage. At necropsy, there was complete encasement of all sump-Penrose drains and partial occlusion of all open peritoneal incisions by omentum adhered to the abdominal wound edges. Peritonitis was not grossly evident, but all dogs showed histologic evidence of an acute inflammatory reaction associated with the drain or wound edge.
在12只正常犬中检查了低粘度油基造影剂在腹腔内的弥散和引流模式。通过头侧或尾侧腹腔内注射造影剂，并采用贮液-彭罗斯引流法或开放腹腔引流法进行引流。在建立腹腔引流前后的96小时内拍摄X光片。每只犬实施安乐死后进行尸检。头侧注射造影剂后15至30分钟、尾侧注射后1至2小时，造影剂弥散至整个腹腔。开放腹腔引流后6小时内、贮液-彭罗斯引流后24至48小时内，大部分造影剂排出。尸检时，所有贮液-彭罗斯引流管均被完全包裹，所有开放腹腔切口均被附着于腹部伤口边缘的大网膜部分阻塞。腹膜炎在大体上不明显，但所有犬均显示出与引流管或伤口边缘相关的急性炎症反应的组织学证据。
