Objective:To compare the effect of two kinds of tube feeding nutrient methods on patients with mechanical ventilation. Methods:Fifty patients with gastrointestinal nutrition and mechanical ventilation were divided randomly into observation group and control group.The observation group was with infusion tube feeding

and the control group with filling tube feeding.Then the incidence of bloating

vomits

food reflu and ventilator-associated pneumonia were recorded in each group.Results:The incidence rate of bloating

vomits

food reflu and ventilator-associated pneumonia were 24%

4%

10.7% and 12% in observation group

while the rates in control group were 80%

20%

34.3% and 32% retrospectively.There were statistically significant difference between the two groups.Conclusion:It was suggested that infusion tube feeding nutrition could obviously reduce the occurrence of bloating

vomits

food reflu and ventilator-associated pneumonia.
