Abstract:
Objective:To anaylyze the influencing factors of peripheral arterial catheter-related bloodstream infection (CRBSI), and provide theoretical basis for clinical medical staff to control CRBSI.Methods:Adopting cross-sectional survey method. Convenient sampling method was used to select 331 patients with arterial catheterization in Tianjin Beichen Hospital from January 2021 to January 2022. The general status, catheter related infections,local skin abnormalities and catheterization status of the subjects were collected. The positive microbial culture at the tip of the catheter after extubation was taken as the outcome index, the influencing factors of peripheral arterial CRBSI were analyzed.Results:The incidence of CRBSI was 8.15% (27/331). Adjusted Logistic regression showed that age ( OR=3.013, 95% CI 1.158-14.365), local abnormality ( OR=3.357, 95% CI 1.670-9.269), number of days of catheterization ( OR=2.338, 95% CI 1.127-4.183) and location of catheterization (lower limb) ( OR=3.325, 95% CI 1.007-3.954) were the risk factors of peripheral artery CRBSI (all P<0.05). Conclusions:Peripheral artery CRBSI is more likely to occur in ICU patients aged ≥65 years, with local skin abnormalities, catheterization days ≥14 d and catheterization site in lower extremity. Paying attention to the elderly, paying attention to the integrity of the sterile barrier at the puncture site, shortening the catheterization days and avoiding lower extremity puncture can reduce the occurrence of peripheral artery CRBSI.
