BACKGROUND
Diarrhea is a common problem in critical illness. The aim of this study was to investigate the effect of probiotic treatment with Lactobacillus rhamnosus GG on established diarrhea in critically ill patients.
METHODS
This prospective randomized blinded trial in the adult intensive care unit of a large tertiary referral teaching hospital compared probiotic treatment with placebo. Thirty-six consecutive critically ill enterally fed adults with diarrhea were randomized to receive 2 capsules per day for 7 days of either Lactobacillus GG in an inulin base (Culturelle) or inulin alone (placebo). Diarrhea was defined as ≥3 unformed stools or >200 mL stool volume within 24 hours. Prospectively defined primary end point was duration of diarrhea, and secondary end point was mean number of loose stools per day during the 14 days from the first capsule. Results by intention-to-treat analysis: No significant difference was observed for any end point. There was a trend toward more diarrhea in the probiotic treatment group. Mean (standard deviation) duration of diarrhea was 3.83 (2.39) days for the probiotic group and 2.56 (1.85) days for the placebo group (P = .096). Mean number of loose stools per day during the 14 days from the first capsule was 1.58 (0.88) in the probiotic group and 1.10 (0.79) in the placebo group (P = .150).
CONCLUSIONS
This study does not support the use of Lactobacillus GG as a treatment for established diarrhea in enterally fed critically ill patients.
