Abstract
Previous studies have correlated intolerance of isotonic, intact protein enteral solutions with hypoalbuminemia. The purpose of this retrospective study was to determine whether the level of serum albumin (SA) influenced tolerance of such an enteral nutrient solution (ENS). All patients who received Entrition during 1987 for a minimum of 48 hr were studied for the first 10 days of enteral feeding. Documentation included SA, medications, stool frequency, gastric residuals (GR), and daily caloric intake. ENS intolerance was defined as greater than 3 stools/day for greater than 48 hr or GR greater than twice the hourly infusion rate for greater than 48 hr. Patients were categorized into two groups: those with SA greater than or equal to 2.5 g/dl (group 1) and those with SA less than 2.5 g/dl (group II). Of 88 patients studied, 48 (86%) in group I and 28 (88%) in group II tolerated the ENS. Eight (14%) in group I and 4 (12%) in group II experienced ENS intolerance. There was no statistically significant difference in the frequency of ENS intolerance between these two groups (p < 0.05). Also, 97% of all those with a SA less than 2.5 g/dl were fed 80% or more of their estimated caloric requirements. We concluded that ENS tolerance was not affected by the SA level and patients with hypoalbuminemia (SA < 2.5 g/dl) could be fed enterally.
