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<0.05). 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.
