Objective To evaluate the application effect of feedforward control combined with phased intervention in postoperative enteral nutrition patients with gastric cancer after radical gastrectomy. Methods A total of 84 gastric cancer patients admitted to Jiyuan Cancer Hospital from October 2021 to October 2023 who were proposed to undergo radical gastric cancer treatment were selected and divided into the control group (n=42) and the study group (n=42) by the randomized numerical table method. Both groups received enteral nutrition after the operation. The control group received phased intervention during this period, while the study group received feedforward control combined with phased intervention. Both groups were intervened until exhaust was restored for 3 to 5 days. The energy intake of the patients was evaluated, the levels of albumin (ALB) and prealbumin (PAB) were detected to evaluate the nutritional status of the patients, and the feeding tolerance of the patients was counted. Results ① Energy intake: After intervention for 2 and 3 days, the energy intake of the study group was significantly higher than that of the control group (P<0.05). ② Nutritional status: After the intervention, the levels of ALB and PAB in the study group were significantly higher than those in the control group (P<0.05). ③ Feeding tolerance: The incidence of abdominal distension and abdominal pain in the study group was lower than that in the control group (P<0.05), but there was no statistically significant difference in the incidence of other feeding intolerance events (including gastric retention, diarrhea, nausea and vomiting) between the two groups (P >0.05). Conclusion The application of feedforward control combined with phased intervention during enteral nutrition after radical gastrectomy for gastric cancer has a significant effect, which can improve the patient’s energy intake and nutritional status, and reduce the occurrence of feeding intolerance.
