不同间隔时间冲管对降低鼻胃管堵管的研究

Study on the reducing of occlusione of nasogastric tube by distinct time compartment of the washing pipe

目的探讨长期肠内营养后留置鼻胃管行脉冲式冲管间隔的时间,减少鼻胃管堵管的发生。方法将174例长期留置鼻胃管的脑血管意外患者随机分为A组、B组、对照组,每组58例,分别予不同间隔时间采用温开水脉冲式冲管,A组1次/4h,B组1次/6h,对照组1次/8h,比较三组患者堵管发生率及并发症发生情况。结果对照组堵管率为43.1%;B组堵管率为27.9%;A组堵管率为10.3%。A组与对照组比较差异有显著意义,B组与对照组比较差异无显著意义;三组患者并发症发生情况比较差异无显著意义。结论1次/4h冲管效果明显好于1次/8h及1次/6h。

Objective To study the effect of flushing pipe method on nasogastric tube blockage at different times and to provide effective precaution against blockage in enteral nutrition tube for clinical application. Method 174 ca- ses of cerebral vascular accident patients with long-term indwelling nasogastric tube were randomly divided into con- trol group, group A and group B, 58 cases in each group. Use flushing pipe method of impulse type to flush the tube once with 20 ml warm boiled water at different times （Q 8 h, Q 6 h, Q 4 h） and compare the blockage rate of nasogastric tube and complications of three groups. Result The blockage rate of the control group, group A and group B is 43.1%, 27.9 % and 10.3 ~ respectively. Complications of enteral nutrition incidence rate of three group are not statistically significant. （P^0.05）Conclusion Using flushing pipe method of impulse type to flush the long- term nasogastric tube once with warm boiled water every four hours can maintain the enteral nutrition tube function- al, reduce the blockage rate and relieve patients of heavy financial burden. It is worthy for application further in clin- ical work.
