Analysis of Pathogenic Bacteria Distribution and Influencing Factors of Urinary Tract Infection in Patients with Severe Traumatic Brain Injury
Objective:To explore the pathogenic bacteria distribution and influencing factors of urinary tract infection in patients with traumatic brain injury(TBI).Method:The clinical data of 132 patients with severe TBI admitted to Sir Run Run Shaw Hospital,School of Medicine,Zhejiang University from January 2020 to September 2022 were retrospectively analyzed.General data of all patients were collected.The urinary tract infection condition and the distribution condition of pathogenic bacteria and grouping condition of all patients were analyzed.The general data of the two groups were compared.The influencing factors of urinary tract infection in severe TBI patients were analyzed.Result:Among 132 patients,24 happened urinary tract infection,the incidence was 18.18%and they were included in the infection group.In 24 patients with urinary tract infection,a total of 39 strains were detected,including 21 gram-negative bacteria,7 gram-positive bacteria and 11 fungi.The duration of hospital stay and indentation catheter in the infected group was longer than that in the uninfected group,the proportions of open TBI,diabetes mellitus,and complications≥2 were higher than those in the uninfected group,and the Glasgow coma scale(GCS)score at admission was lower than that in the uninfected group,the differences were statistically significant(P<0.05).Combined diabetes mellitus,GCS score at admission and indwelling catheter time were the influencing factors of urinary tract infection in severe TBI patients(P<0.05).Conclusion:Patients with severe TBI urinary tract infection are mainly dominated by gram-negative bacteria,and diabetes mellitus,GCS score at admission and indentation catheter time are influential factors for the occurrence of urinary tract infection in severe TBI patients.
