床边超声监测胃残余量在重症患者早期肠内营养管理中的应用研究

目的 观察床边超声监测胃残余量在重症患者早期肠内营养管理中的应用效果.方法 将120例患者按随机数字表分为对照组和观察组各60例.对照组患者采用回抽胃液法监测胃残余量,观察组患者采用床边超声监测胃残余量.比较两组患者的肠内营养达标情况、营养状况、喂养不耐受情况.结果 肠内营养第5天,观察组肠内营养达标率为70.0％,高...

Research on application of bedside ultrasound monitoring gastric residual amount on early management of enteral nutrition for severe patients

Objective To observe the effect of bedside ultrasound monitoring gastric residual amount on early management of enteral nutrition for critical patients.Method Divide 120 patients into observation group(n=60)and control group(n=60)by random number table.Monitor gastric residual amount of patients in control group by withdrawing gastric fluid and monitor gastric residual amount of patients in observation group by bedside ultrasound monitoring.Compare the standard-reaching of enteral nutrition,nutritional status and feeding intolerance between two groups.Result The standard-reaching rate of enteral nutrition is 70.0%in observation group,which is higher than 51.7%in control group in the fifth day of enteral nutrition.The standard-reaching rate of enteral nutrition is 96.7%in observation group,which is higher than 81.7%in control group in the seventh day of enteral nutrition.The difference is significant(P<0.05).Prealbumin,serum albumin,triceps skinfold thickness and arm muscle circumference are(216.4±16.4)g/L,(37.5±5.3)g/L,(9.4±0.7)mm and(20.6±0.7)cm in observation group,which is higher than(183.5±12.5)g/L,(32.8±4.2)g/L,(8.4±0.8)mm and(19.0±0.5)cm in control group in the 14th day of admission.The difference is significant(P<0.05).Incidence of vomiting,abdominal distension,diarrhea and abdominal hypertension are all lower in observation group than in control group,the difference is significant(P<0.05).There are four cases of abdominal compartment syndrome in control group and non in observation group.Conclusion Bedside ultrasound monitoring gastric residual amount applied in early management of enteral nutrition for critical patients can improve the standard-reaching rate of enteral nutrition,improve nutritional status and relieve feeding intolerance.
