title: Long term peritoneal nutrition in dogs, both normal and after intestinal resection.
abstract: We carried out total and prolonged peritoneal nutrition (PN) in a group of healthy dogs and in another group that had previously undergone an 80% resection of the small intestine. A third group of animals underwent the same operation but did not receive intraperitoneal nutrition, as they formed the control group. A nutritive mixture was used, composed of glucose fat emulsion, aminoacids, ions, trace elements, insulin and vitamins. The caloric rate was 45 kcal/kg/day. Peritoneal nutrition lasted 30 days. Periodical clinical controls were made for biochemical, hematological, microbiological and histopathological analyses. We found two episodes of peritonitis out of a total of 19 dogs subjected to PN. Hyper- and hypoglycemia occurred in the animals with PN and that had not undergone intestinal resection there were also increases in triglyceride, free fatty acid and cholesterol levels as well as a reduction of albumin. We observed a greater decrease in albumin and urea nitrogen and a greater weight loss in the animals underwent intestinal resection. The quantity absorbed was greater than 95% of the volume infused over the four week period. In all the animals subjected to PN we found hyperplasia and phagocytic phenomena in the peritoneal mesothelium cells after 30 days of peritoneal nutrition, symptoms which disappeared one month after this kind of nutrition was stopped.
