RESUMO
Objective:To determine the effect of total parenteral nutrition(TPN) supplemented with glutamine(Gln) on the concentration of plasma lipopolysaccharide(LPS)of the multiple organ dysfunction syndrome(MODS) patients.Methods:40 MODS patients in the ICU were randomly divided into routine group(Group A,n=20),the Gln+TPN treatment Group (Group B,n=20).The two groups of patients received treatment of parenteral nutrition with equal nitrogen and equal calorie.Group A were given routine TPN,and Group B were given routine TPN and Gln 0.27 g/(kg?d)[i.e.dipeptiven 0.4 g/(kg?d)] for seven days.The concentration of plasma Gln and LPS were checked before the treatment of TPN and on the first,the third and the seventh day after the treatment of TPN.At the same time 20 healthy blood donators were chosen as the healthy control group(Group C).Results:Before treatment the concentration of plasma Gln of the two patient groups were both lower than that of Group C(P0.05).On the first,the third and the seventh day of the treatment of TPN,the concentration of plasma Gln of Group A was lower than that of Group B(P0.05).After the treatment of Gln plus TPN,the concentration of plasma LPS of Group B was lower than that of Group A(P0.05).Conclusion:The Gln(dipeptiven) can help to decrease the concentration of plasma LPS and the TPN treatment time of the MODS patients.
