Early parenteral nutrition in enterectomized dogs

Abstract

ABSTRACT: The aim of this study was to explore the role of early central parenteral nutrition support with and without lipid emulsion in enterectomized dogs undergoing small bowel partial resection. Enterectomized dogs often cannot be fed properly via an oral or enteral route immediately post-surgery. After enterectomy, the animals received parenteral nutrition or crystalloid solution until they were able to voluntarily take in an oral diet. All dogs were recruited at the University of Sao Paulo veterinary teaching hospital. Eighteen dogs with intussusception, a foreign intestinal body, linear foreign intestinal body, or intussusception associated with a foreign intestinal body underwent enterectomy surgery and were randomly assigned to receive one of three treatments: crystalloid solution (CS group), parenteral nutrition with a mix of glucose and amino acids (GA group) or parenteral nutrition with a mix of glucose, amino acids and lipids (GAL group). A serum chemistry panel and complete blood count were collected prior to surgery and at the end of the study. Albumin increased in the GA and GAL group (p=0.042 and p=0.038 respectively) after hospitalization, but no significant differences were identified among the groups. Body weight decreased by 4.9% (p=0.042) in the CS group, but there were no significant changes in the GAL and GA groups. There was a significant decrease in the recovery scores in the GA and GAL groups during hospitalization (p=0.039 in both groups). Early parenteral nutrition was beneficial for patient recovery in post-surgical small bowel partial resection, indicating better quality, and no major complications or side effects were observed during the hospitalization period in the studied dogs.
