Abstract:Objective To investigate the effects of somatostatin combined with erythromycin on postoperative gastrointestinal function, immunity and inflammatory factors in patients with abdominal injury. Methods Totally 150 patients with abdominal injury treated by gastrointestinal surgery in Qingdao Central Hospital from September 2018 to March 2019 were randomly divided into control group (routine symptomatic treatment after operation) and single drug group (routine symptomatic treatment + erythromycin) and the combination group (conventional symptom + somatostatin + erythromycin), 50 cases in each group, to observe the recovery of gastrointestinal function in each group and record the gastrointestinal decompression drainage on the 1st, 3rd, 5th postoperative group. The levels of serum immune factors (IgM, IgA, IgG) and inflammatory factors (IL-6, IL-8, TNF-α) were measured before and 1 day after surgery and 5 days after surgery. Results Compared with the three groups of bowel sound recovery time, the first anal exhaust time, defecation time and hospitalization time among 3 groups, the combined group was the shortest, the control group was the longest (P?0.05). The difference was statistically significant (P?< 0.05). On the 1st, 3rd, and 5th postoperative day, the gastrointestinal decompression tube drainage was compared, and the variance analysis of repeated measures was used. There was a difference in the gastrointestinal decompression tube drainage at different time points (P?0.05); there were differences in the drainage volume of the three groups of gastrointestinal decompression tubes (P?0.05); the change trends of gastrointestinal decompression tube drainage in 3 groups were statistically different (P?0.05). The comparison of IgM, IgA, and IgG on the 1st and 5th day after operation was compared. The variance analysis of repeated measurement data showed that: there were differences between different time points (P?0.05), among 3 groups (P?0.05), and in the trends of IgM, IgA, and IgG levels (P?0.05). There were significant differences in IL-6, IL-8 and TNF-α among the three groups at different time points (P?0.05); there were differences in IL-6, IL-8 and TNF-α among the three groups (P?0.05); the change trend of IL-6, IL-8 and TNF-α among the three groups was different (P?< 0.05). The incidence of postoperative intestinal-related complications were 8.0%, 22.0%, and 34.0%, respectively. The combination group was the lowest, and the control group was the highest (P?0.05). Conclusion The combination of somatostatin and erythromycin for abdominal injury can promote the recovery of intestinal function and immune function, and inhibit the level of serum inflammatory factors, which is of great value for the prevention and treatment of abdominal infection and intestinal paralysis.
