超声引导延长鼻胃管置入深度在肠内营养中的安全性及有效性研究

Safety and efficacy of under bedside ultrasound guidance for critical patients enteral nutrition support

目的探讨重症超声引导下延长鼻胃管置入深度在重症患者肠内营养中的安全性和有效性。方法选择2018年7月至2019年6月无锡市人民医院收治行肠内营养重症患者56例为研究对象,按照随机数字表法分为观察组29例和对照组27例,对照组患者采用传统鼻胃管置入深度(45~55 cm),观察组患者采用超声引导下延长鼻胃管置入深度至胃窦部幽门前,观察肠内营养并发症发生率。结果观察组鼻胃管置入深度、胃残留量、误吸发生率分别为(68.07±2.81)cm、(76.10±37.02)ml、6.89%(2/29),对照组分别为(53.92±3.12)cm、(137.20±58.40)ml、29.63%(8/27),2组比较差异有统计学意义(t值为17.669、7.272,χ^2值为4.926,P<0.01或0.05)。腹泻发生率比较差异无统计学意义(P>0.05)。结论对于行肠内营养的重症患者,超声引导下延长鼻胃管置入深度安全且有效。

Objective To evaluate the efficacy and safety of under bedside ultrasound guidance for critical patients enteral nutrition support.Methods A total of 56 critical patients underwent the long-term enteral nutrition therapy form July 2018 to June 2019 in Wuxi People′s Hospital were selected.According to the random number table method,they were divided into observation group(29 cases)and control group(27 cases).The observation group was extending the depth of nasogastric tube under the guidance of ultrasoundreated,while control group was treated with depth of gastric tube insertion(45-55 cm).The complications,time of mechanical ventilation and the length of ICU stay between the two groups were compared.Results The depth of nasogastric tube,gastric residual volume and the incidence of aspiration were(68.07±2.81)cm,(76.10±37.02)ml,6.89%(2/29)in the observation group and(53.92±3.12)cm,(137.20±58.40)ml,29.63%(8/27)in the control group,and there were statistically significant difference(t values were 17.669,7.272,χ^2 value was 4.926,P<0.01 or 0.05).There was no statistically significant difference in the incidence of abdominal distention between the two group(P>0.05).Conclusions It is safe and effective to extend the placement depth of nasogastric tube under the guidance of ultrasound for critical ill patients.
