床边胃镜引导下留置鼻肠管在危重病人肠内营养中的应用效果

目的:探讨床边胃镜引导下留置鼻肠管在危重病人肠内营养中的应用效果。方法:选取ICU危重病人60例，随机分为观察组和对照组，各30例。对照组留置鼻胃管进行营养支持，观察组采用鼻肠管营养支持。比较2组病人干预第1、10天的营养指标；比较2组置管成功率，以及恶心呕吐、腹胀、腹泻、反流误吸以及堵管等并发症发生情况。结果:干预第1天，2组病人血清白蛋白、前白蛋白和血红蛋白差异均无统计学意义（P>0.05）；干预第10天，鼻肠管组病人各项指标均高于鼻胃管组（P<0.05）。2组病人置管成功率均为100%；鼻肠管组并发症发生率明显低于鼻胃管组（P<0.01）。结论:床边胃镜引导下留置鼻肠管有助于改善病人营养状况，并减少肠内营养并发症的发生。

Application effect of indwelling nasal-intestinal tube guided by bedside gastroscope in enteral nutrition of critical patients

Objective:To investigate the application effects of indwelling nasal-intestinal tube guided by bedside gastroscope in enteral nutrition of critical patients.Methods:Sixty critical patients were randomly divided into the observation group(30 cases indwelled with nasal-intestinal tube for nutrition support)and control group(30 cases indwelled with nasogastric tube for nutrition support).The nutrition indexes between two groups on the first and 10th day of intervention were compared.The success rate of catheterization,nausea vomiting,abdominal distension,diarrhea,anti-flow aspiration and tube plugging between two groups were compared.Results: The differences of the levels of serum albumin(ALB),prealbumin(PA)and hemoglobin(Hb)between two groups on the first day of intervention were not statistically significant(P >0.05).On the 10th day,the levels of indexes in observation group were higher than those in control group(P<0.05).The success rates of catheterization in two group were 100％,and the incidence rate of complications in observation group was significantly lower than that in control group(P<0.01).Conclusions:The indwelling nasal-intestinal tube guided by bedside gastroscope can significantly improve the nutritional status,and reduce the incidence of enteral nutrition complication of patients.
