超声辅助四步法鼻空肠管置入在ICU中的应用

目的:探讨超声辅助四步法鼻空肠管置入在ICU重症病人中的应用价值。方法:33例拟行肠内营养支持的ICU重症病人采用超声引导四步法进行鼻空肠管置入,即通过超声判断鼻空肠管置入食道内、鼻空肠管置入胃内、鼻空肠管置入幽门后、最后确认鼻空肠管位置。结果:成功置入28例,失败3例,失败原因为通过幽门之假象及病人胃蠕动消失,鼻空肠管末端贴于胃大弯处,无法弯曲进入胃窦、幽门。结论:超声辅助四步法床旁鼻空肠管置入技术是一种新的鼻空肠管置入技术,操作简单,有效、无创,可重复性且成功率较高,可预防或减少并发症的发生。

Short-term clinical outcomes in extremely/very low birth weight infants with individual nutritional support

Objective: To explore the application value of bedside nasojejunal feeding tube placement using four steps of ultrasonic-assisted method in critical ill patients. Method: Thirty-three critical ill patients receiving enteral nutrition were enrolled. We adopt four steps of ultrasonic guidance to conduct nasojejunal feeding tube placement. The details were as followed: nasojejunal feeding tube placement within the esophagus, within Gastric body, within After the pylorus, at last the location of nasojejunal feeding tube. Results: The placement of nasojejunal feeding tube was successful in 28 patients, failed in 2 patients. The failure reason include that the false appearance of pylorus through and the lost gastrointestinal motility led to the sticking of nasojejunal feeding tube on arcus major ventriculi and it couldn't enter into gastric antrum and pylorus. Conclusion: The application of nasojejunal feeding tube placement by four steps of ultrasonic-assisted is a novel feeding technique, and it's simple, effective, noninvasive and repeatability procedure with a high success rate and low complications.
