They were randomly assigned to either an ultrasound group or a control group, with each group consisting of 30 cases. In the ultrasound group, gastric residual volume was monitored using bedside ultrasound measurement of gastric antrum area, while in the control group it was monitored using gastric fluid withdrawal method. The monitoring frequency was set at once every 4\u202fhours, and enteral nutrition was dynamically adjusted based on the monitoring results. The operation time of gastric residual volume monitoring, standard rate of enteral nutrition within 48\u202fh, standard time of enteral nutrition, and the incidence of adverse reactions were compared between the two groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The operation time for gastric residual monitoring and the duration required for enteral nutrition to reach the standard were significantly shorter in the ultrasound group compared to the control group (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.05).
