The effects of enteral nutrition on nutrition status,respiratory function,infection control for patients who were undergoing ventilator therapy

Objective To evaluate the effects of enteral nutrition on thepatients who were undergoing the ventilator therapy. Methods We used randomized controlled study design,divided into enteral group,parenteral group and the common group.EN and PN groups were undergoing 6 days nutrition support of equal nitrogen and equal calorie;the common group was undergoing the routine intravenous therapy,compared the different effects on blood gas indexes,nitrogen balance,protein of blood plasma and prognosis. Results The EN group had the similar results in 6 days accumulated nitrogen balance and blood plasma pro-albumin with PN group,had significant differences with the common group (P<0.05).The similar blood gas parameters were observed int three groups,but the EN group had the best parameters.The lung infection rates were similar in former two groups,better than the common group.The nutrition cost of PN group was significantly higher than EN group (P<0.05) and had the puncture complications. Conclusion Synthesizing the clinical effects,enteral nutrition was a better nutrition support approach for the patients who were undergoing ventilator therapy.
