Abstract:
Objective To analyze the risk factors of subclavian venous catheter-related infections in patients with traumatic hemorrhagic shock (THS) and provide a basis for prevention and control of the infection. Methods A retrospective study was conducted. 357 patients with THS and indwelling of subclavian vein catheter admitted in the Department of Emergency of Affiliated Hospital of Sichuan Provincial Luzhou Medical College were enrolled, and according to the infection state, they were divided into infection group (56 cases) and non-infection group (301 cases). The patients' data of gender, age, history of underlying disease, catheter position, catheter indwelling time, time staying in hospital, situation of antimicrobial drug used, application of tracheotomy or not, white blood cell count (WBC) levels, etc were collected for univariate analysis. The resulting indexes with statistical significance were applied for carrying out the multivariate logistic regression analysis, and then the independent risk factors involved in the development of subclavian venous catheter-related infections in the shock patients could be screened out.Results In 357 patients with THS, 56 were infected (15.7%). Univariate analysis showed: age ≥ 60 years (χ2 = 19.839,P < 0.001), with diabetes mellitus in past history (χ2 = 6.252,P = 0.012), catheter indwelling time ≥ 7 days (χ2 = 19.261,P < 0.001), time staying in hospital ≥ 7 days (χ2 = 4.315,P = 0.038), time for use of antimicrobial drug≥ 7 days (χ2 = 16.161,P < 0.001), tracheotomy (χ2 = 40.969,P < 0.001), WBC < 4×109/L (χ2 = 39.451,P < 0.001) and the disease severity grade 4 - 5 (χ2 = 8.345,P = 0.004) were the risk factors of subclavian venous catheter-related infections in patients with THS. Multivariate analysis showed: catheter indwelling time ≥ 7 day [odds ratio (OR) = 16.713, 95% confidence interval (95%CI) 3.651 - 76.624), tracheotomy (OR = 6.861, 95%CI 2.377 - 18.246), WBC < 4×109/L (OR = 4.903, 95%CI 1.887 - 12.643) were the independent risk factors of subclavian venous catheter-related infections in THS patients.Conclusion The strict implementation of aseptic catheterization, shortening the time of catheter indwelling as much as possible and the rational use of antibiotics can effectively reduce and prevent the incidence of venous catheter-related infection in THS patients.
