改良脉冲式冲管法预防鼻胃管堵管的效果

Effects of Improved Pulsed Washpipe Method in Preventing Nasogastric Tube Occlusion

目的探讨脉冲式冲管在预防鼻胃管堵塞中的效果。方法将2007年3月至2010年8月入住ICU且使用鼻胃管的102例危重症患者分为试验组58例和对照组44例,管饲后分别采用改良脉冲式法及传统方法冲洗管道,比较两组患者的堵管发生率及并发症发生情况。结果试验组堵管发生率(3.4%)低于对照组(15.9%),差异有统计学意义(P<0.05);两组患者均出现不同程度的腹泻、胃潴留、食物反流、消化道出血等并发症,差异无统计学意义(P>0.05)。结论采用改良的脉冲式推注法冲管能有效预防鼻胃管堵塞,且不增加并发症的发生率。

Objective To explore the effect of,pulse washpipe in preventing nasogastric tube occlusion in critical patients. Methods From March 2007 to August 2010,102 critical patients with nasogastric tube enteral nutrition were divided in to experiment group（n=58）and control group（n=44）. The patients in the control group and the experiment group adopted the traditional washpipe method and improved pulse injection method respectively. The incidences of nasogastric tube occlusion and complications were compared between the two groups. Results The incidence of nasogastric tube occlusion（3.4%） in experiment group was significantly lower than that （15. 9 %）of control group （P〈0.05）. The two group of patients were presented with different degrees of complications of diarrhea, stomach retention, food reverse flow and gastrointestinal bleeding, without statistically significant difference （P 〉 0. 05）. Conclusion The improved pulsed washpipe method can effectively prevent stomach tube obstruction and do not increase the incldence of complications.
