Abstract
The effect of high nitrogen Criticare and Vivonex on nutritional repletion was evaluated in 12 patients with malnutrition secondary to pancreatic insufficiency. The patients were randomized to receive either Criticare HN or Vivonex HN for a total period of 9 days. Each patient received 3000 kcal/day of either preparation, in addition to 1000 kcal of solid food. A significant weight gain was encountered in the group of patients receiving Criticare HN. Increased blood urea nitrogen was encountered in both groups of patients. All patients tolerated both diets well without evidence of relapse of their pancreatitis. No significant complications were encountered. Our results indicate that Criticare HN is of superior nutritional value, but both preparations resulted in increased blood urea nitrogen retention.
