ABSTRACT

Objective:To explore the effect of high fat and low sugar enteral nutrition support on ventilatory function and immune function in patients with chronic obstructive pulmonary disease(COPD) undergoing mechanical ventilation.Methods:From January 2018 to December 2019, 96 COPD patients treated in Zhuji People's Hospital were divided into observation group and control group by simple random sampling method, with 48 cases in each group.The control group was treated with traditional nutrient solution, and the observation group was given high fat and low sugar enteral nutrition.The blood gas analysis, respiratory function, immune function, weaning time and weaning success rate were observed before and after treatment.Results:After treatment, the arterial oxygen partial pressure(PaO 2)[(10.08±0.49)kPa], the blood oxygen saturation (SpO 2)[(96.46±2.15)%] in the observation group were higher than those in the control group[(9.53±0.46)kPa, (95.04±2.08)%]( t=5.670, 3.289, all P<0.05), and the carbon dioxide partial pressure (PaCO 2) [(6.42±0.27)kPa] was lower than that in the control group [(7.33±0.25)kPa]( t=17.134, P<0.05). After treatment, the forced vital capacity(FVC) [(3.03±0.52)L], forced expiratory volume in one second(FEV 1)[(1.61±0.33)L], peak expiratory flow(PEF)(0.54±0.08) in the observation group were higher than those in the control group [(2.78±0.45)L, (1.42±0.31)L, (0.49±0.07)]( t=2.519, 2.907, 3.259, all P<0.05). The immunoglobulin G [(12.45±1.32)g/L], immunoglobulin M [(1.88±0.34)g/L] and immunoglobulin A [(2.68±0.47)g/L] in the observation group were higher than those in the control group [(11.66±1.28)g/L, (1.65±0.37)g/L, (2.38±0.45)g/L] ( t=2.977, 3.171, 3.194, all P<0.05). The weaning time of the observation group was (6.94±1.55)d, which was lower than that of the control group [(8.73±1.41)d] ( t=5.919, P<0.05). The success rate of weaning of the observation group (91.67%) was higher than that of the control group (72.92%) (χ 2=5.790, P<0.05). Conclusion:High fat and low sugar enteral nutrition support can improve the ventilation indicators and immune function indicators of COPD patients with mechanical ventilation, shorten the time of mechanical ventilation, and improve the success rate of weaning.
