Early enteral nutrition in puppies with parvovirus enteritis

Abstract

Canine parvovirus (CPV) enteritis is an important cause of severe, often fatal enteritis in dogs. Survival rates can be as high as 90% when puppies receive intensive treatment at tertiary veterinary facilities. No disease-specific therapies exist and treatment consists of supportive therapies. These therapies include intensive fluid therapy, antibiotic therapy, anti-emetic therapy and analgesic therapy. Anthelminthic therapy is added to eliminate possible concurrent verminosis. One supportive measure which was found to be associated with more rapid clinical improvement in canine parvovirus enteritis is the early implementation of enteral nutrition. This article reviews the research findings in various aspects of early enteral nutrition in both human and animal critical care. Different naso-enteric feeding devices are compared and various feeding methods for the various clinical scenarios encountered with canine parvovirus enteritis are briefly discussed. The concept of gastric residual volume and its potential role in early enteral nutrition is evaluated. The authors' view on how these research findings can be practically applied to treat puppies with canine parvovirus enteritis is presented. A detailed description is given on the decision making process in early enteral nutrition in a tertiary facility treating puppies with canine parvovirus enteritis.
