Elemental diet administered nasogastrically without starter regimens to patients with inflammatory bowel disease

Abstract

The present study questions the concept of routinely using 'starter regimens' at the outset of enteral feeding with chemically defined elemental diets. A hypertonic elemental diet with an osmolality of 630 mOsm/kg was administered by 24-hr nasogastric infusion to 12 patients with exacerbations of inflammatory bowel disease and to two patients with short bowel syndrome. Starter regimens were not used. Upper gastrointestinal symptoms of nausea, abdominal bloating, and colicky pain occurred transiently in only five of 14 patients. Stool frequency did not increase during full-strength feeding, and daily stool weights decreased significantly (p less than 0.01). These findings show that it is safe to administer undiluted hypertonic elemental diets by constant nasogastric infusion to patients with inflammatory bowel disease. Avoiding starter regimens leads to increased nutrient intake and improved nitrogen balance.
