持续肠内营养对机械通气患者吸入性肺炎发生率影响的临床研究

THE CLINICAL RESEARCH ON THE INFLUENCE OF SUSTAINED EN ON THE INCIDENCE OF INSPIRATORY PNEUMONIA ON MECHANICAL VENTILATION PATIENTS

目的观察持续肠内营养对机械通气患者吸入性肺炎发生率影响。方法将120例机械通气患者,随机分为两组,对照组采用注射器经鼻胃管间歇缓慢推注营养液(能全力)入患者胃内。观察组采用输血器持续输注营养液(能全力),观察治疗2周后进行痰培养检查,对比两组患者吸入性肺炎发生率的差异。结果对照组吸入性肺炎发生率为51.67%,观察组为21.33%,两组比较差异有统计学意义(P<0.05)。结论持续肠内营养可明显降低机械通气患者吸入性肺炎发生率,值得进一步临床推广。

Objective This study is to investigate the influence of sustained EN on the incidence of inspiratory pneumonia on mechanical ventilation patients.Methods Divide 120 mechanical ventilation patients into two groups at random.The intervals transfusion group（the control group） are slowly given nutrition by the syringe through the nasogastric tube,while the observation group are continuously given nutrition by the blood transfusion set.Then observe the differences in the incidence of inspiratory pneumonia between the two groups according to the results of sputum culture.Results The incidence of inspiratory pneumonia of the control group is 51.67%,and the observation group is 21.33%.There is a statistical significance（P〈0.05） in the differences between the two groups.Conclusion This method is worth being popularized in clinical practice because of its effect on reducing the incidence of inspiratory pneumonia of mechanical ventilation patients.
