目的:对床边胃镜引导下留置鼻肠管在危重病人中的应用进行相关分析探讨。方法:将2010年6月至2011年4月的32例本院治疗的患者,随机分组,采用床边胃镜引导下留置鼻肠管进行肠内护理,分别采用常规盲插被动等待法、X线透视下以及内镜引导下3种方法,观察3组留置鼻肠管的成功率,并进行相关分析。结果:常规盲插被动等待法的成功率为33.33%,X线透视的成功率为66.67%,内镜引导的成功率为90.0%。内镜引导下的患者无并发症出现,而X线透视、常规盲插被动等待法均产生了不同程度的恶心呕吐、腹胀腹泻、反流等并发症。结论:3种方法分别有各自的优点,但其中内镜下放置方法较好,成功率高,技术要求低,较适用于危重患者。 Objective: To investigate the application of bedside endoscopy guided indwelling nasogastric tube in critically ill patients. Methods: Thirty-two patients treated in our hospital from June 2010 to April 2011 were randomly divided into enteral nursing with bed gastroscope-guided indwelling nasal and intestine. Conventional blind insertion passive follow-up and X-ray fluoroscopy Under the guidance of endoscopy and three methods to observe the success rate of three groups of nasal cannulation, and correlation analysis. Results: The success rate of conventional passive blind waiting method was 33.33%, the success rate of X - ray fluoroscopy was 66.67%, and the success rate of endoscopic guidance was 90.0%. Endoscopic guided patients without complications, and X-ray, conventional blind insertion passive waiting law have had varying degrees of nausea and vomiting, abdominal distension and diarrhea, reflux and other complications. Conclusion: The three methods have their own advantages, but the endoscopic placement method is better, high success rate, low technical requirements, more suitable for critically ill patients.
