摘要目的 探讨超声引导鼻小肠管置入技术在老年危重患者床边实施的可行性. 方法 回顾分析本院综合ICU床边超声引导鼻小肠管置管的64例老年危重症患者.插管方法经鼻插入胃腔同胃管盲插方法,超声定位引导鼻小肠管进入胃窦,通过幽门入十二指肠球部,无阻力下继续往前推送,到位固定后床边腹部摄X片确定导管头端位置. 结果 64例患者中置管成功57例(89.1％),其中导管头端分别位于十二指肠球部8例、降部8例、升部18例及空肠23例;除1例鼻腔出血、1例镇静后血压下降外无其他明显不良反应. 结论 超声引导鼻小肠管置入技术在ICU老年危重患者床边实施安全可行.

abstractsObjective To investigate the feasibility of inserting and detaining nasointestinal feeding tube in small bowl guided by bedside ultrasound(US)in critically ill elderly patients.Methods This was a retrospective study.Sixty four aged patients(≥ 60 years)in general ICU,the Second Affiliated Hospital of Jiaxing College,received the US-guided nasointestinal feeding tubes inserting and detaining.Feeding tubes passed through nasal and went into the stomach by manual blind method.Under US-guiding condition,the tube passed through the pyloric sphincter and further into the duodenum or jejunum.Finally the correct position of the tube head was assessed by bedside X-ray examination.Results The US-guided nasointestinal feeding tube-detaining technique was successfully operated in 57 patients(89.1％).The feeding tube heads were in the duodenum in thirty four cases(53.1 ％),and in proximal jejunum in twenty-three cases(35.9％).The untoward reaction included the bleeding of nasal cavity in 1 case,and hypotension in another case.Conclusions Bedside US-guided nasointestinal feeding tube placement is safe and feasible in aged critical patients.
