The effect of reducing frequency of gastric residual volume monitoring on enteral nutrition in ICU patients
Objective To evaluate the effect of reducing frequency of gastric residual volume monitoring on enteral feeding-related complication and caloric intake in ICU patients.Methods Patients who admitted to medical ICU,respiratory ICU and emergency ICU of a tertiary A teaching hospital in Beijing during October 2020 to January 2023 and undergoing mechanical ventilation and continuous enteral feeding via nasogastric tube in 24～48 hours were enrolled.According to the random number table method,they were divided into a control group and an intervention group,with 52 cases in each group.Gastric residual volume was monitored daily 12h after enteral nutrition initiation in the intervention group,and every 4 hours in the control group.The enteral feeding-related complication and caloric intake of the 2 groups were recorded after enteral nutrition initiated and until 7th day in ICU.Results 52 cases completed the study in each group respectively.During the first 7 days,the incidence of vomiting and the maximum of gastric residual volume in the experimental group were higher than those in the control group,with no statistically significant differences.No nasogastric tube occlusion was observed in any patients in either group.Compared to the control group,both the caloric intake of 7th day in ICU and the proportion of patients achieving calorie target on 7th day in ICU were significantly higher in the experimental group,with statistically significant differences.Conclusion Reducing the frequency of gastric residual volume monitoring to once a day could significantly increase caloric intake of patients without an increase in enteral feeding-related complication.
