目的探讨不同冲管方式对预防鼻肠管堵塞的影响及作用。方法对2013年11月-2014年4月收治的50例胃癌术后行肠内营养患者,按住院单双号分为试验组(n=27)和对照组(n=23),分别在鼻肠管输注营养液时采用脉冲式冲管和常规缓慢推注冲管方式,观察比较两种不同冲管方式对鼻肠管的堵塞发生情况。结果试验组共冲管513例次,发生堵塞5例次,发生率0.97%;对照组共冲管437例次,发生堵塞18例次,发生率4.12%;两组堵管率差异有统计学意义(χ2=9.867,P=0.002)。结论脉冲式冲管可以预防导管堵塞的发生,是顺利进行肠内营养的有效措施。
Objective To investigate the effects of different methods of tube-washing on the prevention of the occlusion of the nasal tube. Methods Fifty patients with gastric cancer who underwent enteral nutrition after operation from November 2013 to April 2014 were divided into experimental group (n = 27) and control group (n = 23) Intestinal infusion of nutrient solution using pulsed red tube and conventional slow injection method of red tube, observed and compared two different methods of nasal tube congestion on the incidence. Results In the test group, a total of 513 cases were punched, with 5 cases of occlusion occurring, the incidence rate was 0.97%. In the control group, 437 cases were punched, 18 cases were occluded, the incidence rate was 4.12% Significance (χ2 = 9.867, P = 0.002). Conclusion Pulsed red tube can prevent the occurrence of catheter blockage, which is an effective measure for smooth enteral nutrition.
