STD-PN, standard parenteral nutrition; GLN-PN, glutamine dipeptide-supplemented parenteral nutrition. Values are number of nosocomial infections due to microorganism (number of patients). Presumed causative microorganisms based on microbiological culture results.
P < .03
P < .01: GLN-PN vs STD-PN in the nonpancreatic surgery subgroup (Fisher exact test). Fungal species Breslow-Day interaction (P = .021), Staphylococcus aureus Breslow-Day interaction (P = .069). Other comparisons are not significant.
