To investigate and analyze the influencing factors of central venous catheter-associated bloodstream infection in patients with emergency hemorrhagic shock.
According to the inclusion criteria, 249 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, and divided into the infection group (54 cases) and the non-infection group (195 cases) according to whether catheter-related bloodstream infection occurred.Multivariate Logistic regression was used to analyze the relationship between central venous catheter-related bloodstream infection and various influencing factors. The etiological and drug susceptibility test data of peripheral venous blood culture, puncture site samples and catheter tip samples from patients with central venous catheter-associated bloodstream infection were statistically analyzed.
There were significant differences in age, catheterization location, ultrasound-guided puncture, APACHE ⅱ score, catheter indwelling time and application of broad-spectrum antibiotics between the infected group and the non-infected group (P
