摘要
探讨白利度计监测肠内营养患者胃残余量（GRV）的可行性及准确性。选取50例经鼻胃管行肠内营养治疗的患者，分别用超声和白利度计测量GRV，比较两者测量结果的一致性。配对样本t检验显示两种测量方法结果的差异无统计学意义（P〉0．05），Pearson相关分析显示两种测量方式结果呈正相关（r=0．986，P〈0．05），Bland．Altman图分析结果显示两种测量结果具有一致性。研究结果初步提示利用白利度计测量GRV简便易行，可在临床推广。
To investigate the accuracy and feasibility of Brix value on monitoring gastric residual volume （GRV） in patients with enteral nutrition. Fifty patients with enteral nutrition via nasogastric tube were enrolled. The GRV was measured by both ultrasonography and Brix value. The results were compared according to the methods. The Pearson correlation coefficients showed that GRV measured by these two ways was positively correlated （r=0.986, P〈O.05）. Moreover paired sample t-test showed that the discrepancy was not statistically significant （P〉0.05） between different measurements. The consistency was analyzed by Bland-Altman graph, showing that the two measurements were consistent. Brix value is recommended to measure GRV due to its convenience and easy operation.
