Objective To explore the perioperative dietary management in pediatric gastrointestinal surgery and its value based on the concept of accelerated rehabilitation. Methods From January 2017 to June 2019, 70 children who underwent gastrointestinal surgery in our hospital were selected as study subjects. According to the nursing Methods, they were divided into two groups: a control group (given routine perioperative dietary management) and a rehabilitation group (given the perioperative diet management based on the concept of accelerated rehabilitation), with 35 cases in each group. The first exhaust time, first defecation time, first eating time, hospitalization time, and adverse reactions between the two groups were compared. Results After corresponding nursing strategies, the time of first exhaust, first defecation, first eating, and hospitalization in the rehabilitation group were significantly shorter than those in the control group (P<0.05); the incidence rate of adverse reactions in the rehabilitation group was 5.71%, significantly lower than 22.86% in the control group (P<0.05). Conclusion Based on the concept of accelerated rehabilitation, perioperative dietary management can help the children with gastrointestinal surgery shorten treatment time, promote intestinal recovery, avoid various adverse reactions, and is more conducive to the rehabilitation of children than conventional dietary management.
