Contributor(s): Richard Saunders, Virginia Garner-Richardson, Vicki Baldrey

Introduction

  • To insert a catheter via the nasal passages into gastrointestinal tract to provide a route for direct feeding/fluid administration.

Uses

  • Administration of:
    • Nutrition to debilitated or anorexic patient.
    • Nutrition whilst avoiding oral cavity.
    • Drugs or radiographic contrast agents avoiding oral route.

Advantages

  • Simple procedure.
  • Flexible but secure route of administration.
  • Usually well-tolerated by patient.
  • Equipment readily available in practice.

Disadvantages

  • Animal may dislodge tube if not securely fixed.
  • Potential risk of tracheal placement.
  • Stress and collar induced inappetance.
  • Rabbits need a source of long, indigestable fibre in the diet. Many critical care diets for rabbits that contain enough long fibre are too thick to pass down a 4 to 8-Fr feeding tube.
