Abstract:
Objective:To analyze the risk factors for central venous catheter-associated bloodstream infection in patients with emergency hemorrhagic shock.Methods:Patients with hemorrhagic shock and central venous catheterization admitted to the emergency department of Shanghai First People's Hospital from June 2016 to June 2022 were retrospectively analyzed. The patients were divided into infected group and non-infected group according to whether catheter-related bloodstream infection occurred. The puncture site samples and catheter tip samples of infected patients were collected for etiological detection and drug sensitivity test. The difference of baseline data between the two groups was analyzed, and the relationship between central venous catheter-associated infection and influencing factors was analyzed by multivariate logistic regression.Results:A total of 249 patients were included in this study, including 54 patients in the infected group and 195 patients in the non-infected group. There were significant differences in age, catheterization position, ultrasound-guided puncture, acute physiology and chronic health evaluationⅡ(APACHEⅡ) score, catheter retention time and application of broad-spectrum antibiotics between the infected group and the non-infected group (all P<0.05). Multivariate logistic regression analysis showed that advanced age, femoral vein catheterization, no ultrasound-guided puncture, high APACHEⅡ score, long catheter indent time and application of broad-spectrum antibiotics were risk factors for central venous catheter-associated bloodstream infection. Among the 54 infected patients, Staphylococcus epidermidis accounted for 44.4%, followed by Escherichia coli accounted for 24.1% and fungus accounted for 11.1%. The resistance rate of gram-positive cocci to vancomycin was the lowest (3.4%) followed by tetracycline (34.5%), and the highest resistance rate was amoxicillin (100.0%). The resistance rates of gram-negative bacilli to amikacin and ceftriaxone were relatively high, both of which were 94.7%. Conclusions:The risk factors for central venous catheter-related blood stream infection in patients with emergency hemorrhagic shock included advanced age, femoral vein catheterization, no ultrasound-guided puncture, high APACHEⅡ score, long catheter retention time and use of broad-spectrum antibiotics. The common pathogenic bacteria were Staphylococcus epidermidis and Escherichia coli.
