Background/Purpose: In 2012, the intensive care unit (ICU) of Hospital A introduced a gastric residual volume (GRV) enteral nutrition protocol. In 2016, the number of measurements and flow velocity were revised. The purpose of this study was to investigate and compare the protocol implementation status before and after the revision, and to examine the effectiveness of the revised protocol.Method: We collected data retrospectively in 48 and 71 patients before and after revision.RESULTS: There were no significant differences in the rate of GRV≥150 ml, discontinuing the protocol due to an adverse event, reaching the target dose before and after the revision. In addition, the time taken to reach the target dose was significantly increased (p<0.01) , while the daily fluctuation range in blood glucose levels and the deviating doctor’s instruction change were significantly decreased (p<0.01).CONCLUSIONS: It is suggested that the revised protocol is not harmful and allows for more unified enteral nutrition management. In addition, excessive increases in blood glucose may be suppressed. We would like to continue to manage enteral nutrition according to the physical symptoms of patients, centering on the protocol.
