Influencing Factors and Etiological Analysis of Incision Infection after Abdominal Surgery in Patients with Multiple Traumas

Abstract

Objective: To analyze the influencing factors and etiological characteristics of postoperative incision infection in patients with multiple traumas. Methods: A retrospective analysis was carried out on the clinical case data of 195 patients with multiple trauma who underwent abdominal surgery in our hospital. All patients were admitted to the hospital from January 2016 to December 2021. According to the information obtained, the postoperative incision infection and pathogen distribution of the patients were counted, and the risk factors affecting postoperative incision infection were analyzed. Results: According to the analysis, after abdominal surgery, 38 patients had incision infection, and the infection rate was 19.49%. Through the cultivation of pathogenic bacteria, there were 54 strains of pathogenic bacteria, and the highest proportion was gram-negative bacteria, which was 59.26%, and the lowest was fungus at 9.26%; through univariate analysis, it was found that age, hospital stay, white blood cells, albumin, diabetes, C-reactive protein, blood loss and ISS score between the infected and uninfected groups. There was a significant difference (P<0.05); multivariate logistic regression analysis found that incision infection in patients with multiple traumas after abdominal surgery was associated with increased age, increased albumin level, combined diabetes, increased blood loss and ISS score factors (P <0.05). Conclusion: For patients with multiple traumas who underwent abdominal surgery, the probability of postoperative incision infection was higher, and gram-negative bacteria were the main pathogenic bacteria, and postoperative infection was not only related to one factor, but it is related to a variety of factors, and appropriate amount of antibiotics should be given according to the actual situation of the patient.
