Objective: To explore the application of intestinal obstruction catheter combined with enema with Chinese herbs in children with non strangulated intestinal obstruction. Methods: 100 children with non strangulated intestinal obstruction admitted to our hospital from July 2020 to July 2022 were selected as the study subjects. Randomly divided into general enema group (n=50) and Magnolia officinalis exhaust group (n=50), The general enema group was treated with warm saline enema and soapy water enema; The Houpu exhaust group was treated with intestinal obstruction catheter and Houpu exhaust mixture enema. The changes of serum inflammatory factors before and after treatment were analyzed; The time of relieving abdominal distension, time of spontaneous exhaust, time of resuming diet and time of disappearance of gas liquid level were collected in the two groups; The clinical treatment efficiency of the two groups was analyzed. Results: The relieving time of abdominal distension, the time of spontaneous exhaust, the time of resuming diet and the time of disappearance of gas liquid level in the exhaust group of Magnolia officinalis were shorter than those in the general enema group (P<0.05). The levels of IFABP, D-D, PLR and PCT in the exhaust group were lower than those in the general enema group (P<0.05). The clinical cure rate of Magnolia officinalis exhaust group was higher than that of general enema group (P<0.05). Conclusion: Intestinal obstruction catheter combined with traditional Chinese medicine enema of Magnolia officinalis can effectively shorten the time of abdominal distension, exhaust and diet recovery in children with non strangulated intestinal obstruction, reduce inflammatory reaction, and have a definite clinical effect.
