Abstract:Objective To evaluate the clinical effect of clostridium butyricum powder + lactulose + Diet therapy on functional constipation (FC) in children.Methods The 80 children with FC received in our hospital from April 2018 to June 2019 were divided into two groups. The Control Group (40 cases) received routine treatment such as lactulose plus Diet therapy, while the observation group (40 cases) was treated with clostridium butyricum powder. The level of substance P was determined by radioimmunoassay, and the level of somatostatin was determined by enzyme-linked immunosorbent assay; the rate of dry and hard stools, the rate of defecation pain, and the rate of defecation frequency < 1 time/d were observed; the defecation rate of the children was observed. Time to return to normal, length of hospital stay, total curative effect, and occurrence of related adverse reactions were recorded.Results After treatment, the serum SP level in the observation group was higher than that in the control group (P < 0.05), and the SS level was lower than that in the control group (P < 0.05); the rate of dry and hard stool, the rate of painful defecation, and the rate of defecation frequency less than 1 time/d were lower than that in the control group (P < 0.05); the defecation recovery was normal and the days of hospitalization were shorter than that in the control group (P < 0.05), and the total efficiency of treatment was higher than that in the control group (P < 0.05). There was no statistically significant difference in the total incidence of adverse reactions compared with the control group (P > 0.05).Conclusion Lactulose, diet therapy, and clostridium butyricum powder were used in FC clinical treatment, can improve the clinical symptoms and signs of children, improve the overall efficacy, and will not cause serious adverse reactions with ideal safety.
