Research on oxygen therapy effect for three enteral nutrition patterns of AECOPD patients with non-invasive ventilation / 肠外与肠内营养

ABSTRACT

Objective:Comparison of oxygen therapy effect between three different enteral nutrition solutions was carried out on AECOPD patients with non-invasive ventilation.Methods:A total of 96 patients with acute exacerbation of COPD were divided into three groups of 32 respectively according to the admission order in this prospective studya continuous feeding group,an intermittent feeding group,and a regular bolus feeding group.Arterial blood gas parameters including PH,PaO2,PaCO2,PaO2/FiO2 of three groups on third day,fifth day,seventh day were recorded and compared to evaluate the enteral nutrition effect,and meanwhile nutritional support costs,duration of mechanical ventilation,and length of ICU stay between groups were also studied.Results:PH Values of continuous feeding group and intermittent feeding group on 7th day are7.38 ± 0.04、7.39 ± 0.01 respectively,better than that of regular bolus feeding group (P＜ 0.05).ICU stay period and duration of mechanical ventilation for continuous feeding group are 12.83 ± 3.00 days and 9.50 ± 1.45 respectively,for the intermittent feeding group are 11.90 ± 2.35 and 9.59 ± 1.50 respectively,the two groups gain significant cost-effective advantages compared to the regular bolus feeding group.(P ＜ 0.05),for nutrition support costs,continuous feeding is less than the intermittent feeding.(.P ＜ 0.05).Conclusion:Continuous feeding and intermittent feeding could significantly improve hypoxia symptom and reduce the length of ICU stay and shorten duration of mechanical ventilation in COPD patients compared with regular bolus feeding group.
