不同营养方式对ICU机械通气患者氧合指数及预后的影响

Effect of Different Nutritional Methods on Oxygenation Index and Prognosis of ICU Patients With Mechanical Ventilation

目的探析经鼻胃管鼻饲支持与经鼻空肠管鼻饲支持对ICU机械通气患者氧合指数及预后的影响。方法以本院2019年1月—2020年9月80例ICU机械通气患者为研究对象,根据营养供给方式不同,划分为对照组(n=40,经鼻胃管鼻饲支持)和观察组(n=40,经鼻空肠管鼻饲支持)。对两种支持方式对患者预后和氧合指数所造成的影响进行探讨,以呼吸指标、营养指标、住院时间、机械通气时间以及并发症发生率为研究分析指标。结果相较于对照组,观察组患者呼吸指标更高,差异有统计学意义(P<0.05);且观察组营养指标更优,差异有统计学意义(P<0.05);观察组机械通气时间和住院时间更短,差异有统计学意义(P<0.05);观察组并发症发生率更低,差异有统计学意义(P<0.05)。结论针对ICU机械通气患者,在营养支持上选择经鼻空肠管鼻饲支持方式对患者实施肠内营养支持,能够明显改善患者呼吸指标以及营养指标,患者预后更加良好,有效控制并发症发生频率,具有临床推广应用价值。

Objective To investigate the effects of nasal feeding through nasogastric tube and nasal jejunal tube on oxygenation index and prognosis of ICU patients with mechanical ventilation.Methods A total of 80 patients with mechanical ventilation in ICU from January 2019 to September 2020 were selected as the study subjects.According to different nutritional supply methods,they were divided into control group(n=40,nasogastric tube feeding support)and observation group(n=40,transnasal jejunal tube feeding support).The effects of the two support methods on patients'prognosis and oxygenation index were investigated,and respiratory index,nutritional index,length of hospital stay,mechanical ventilation time and incidence of complications were used as research and analysis indexes.Results Compared with the control group,the respiratory index of observation group was higher,the difference was statistically significant(P<0.05).The nutritional indexes of the observation group were better,and the difference was statistically significant(P<0.05).The duration of mechanical ventilation and hospital stay in the observation group were shorter,and the difference was statistically significant(P<0.05).The incidence of complications was lower in the observation group,and the difference was statistically significant(P<0.05).Conclusion For patients with mechanical ventilation in ICU,enteral nutrition support through nasal jejunal tube feeding can significantly improve the respiratory index and nutritional index of patients,improve the prognosis of patients,effectively control the frequency of complications,and has clinical application value.
