ObjectiveTo investigate the influence of early enteral nutrition with synbiotics on the plasma endotoxin level, the nutritional state, the inflammatory response and the incidence of infectious complications in severely burned patients.MethodsRandomized double blind and control method was employed im the study. Forty severely burned patients were randomly divided into A and B groups with 20 in each group. The patients in group A received early enteral nutrition with synbiotics including four kinds of lactic acid bacteria and four kinds of fibers, while those in group B received early enteral nutrition with synbiotics including only four kinds of fibers. The patients with 80% to 280% coefficient unit burned surface(UBS) were further divided into A1 (n = 10) and B1 (n = 11) groups. The plasma endotoxin level in group A and B was determined dynamically on the 1st, 3rd, 7th, 10th, 14th, and 21st postburn days (PBD), and its abnormal rate in both groups was statistically analyzed in correlation with the normal endotoxin level. meanwhile, the mortality, the incidence of infectious complications and the blood bacterial culture results were compared between the two groups. The plasma levels of IL-1, IL-6 and prognostic inflammatory nutrition index (PINI) were also determined at the above time points.ResultsThe plasma endotoxin level in group A (37.9 +/- 5.4) ng/L was evidently lower than that in group B (59.1 +/- 7.9) ng/L (P < 0.05) on 10 PBD. The abnormal rate of plasma endotoxin in group A (36.7%) was evidently lower than that (49.2%) in group B (P < 0.05). Blood culture was positive in 3 patients in group A, and 5 in group B. There was no obvious difference in the incidence of infectious complication between the two groups. Two patients died in group A and 1 group B. There was no obvious difference in plasma IL-1 level between A1 and B1 groups at different time points. The plasma IL-6 level in A1 group in 10th and 14th PBD was evidently lower than that in B1 group (P < 0.05). The PINI in A1 group on the 10 PBD was remarkably lower than that in B1 group.ConclusionEarly enteral nutrition with synbiotics was helpful in decreasing inflammatory stress response and lowering the plasma endotoxin level. Enteral supplementation of synbiotics might be beneficial to the controlling of burn infection.
