Research Progress on the Risk and Prevention Measures of Peripheral Arterial Catheter Infection in ICU Patients

Abstract

Peripheral arterial catheter (PAC) is an important assistant method in the treatment of critical patients. However, the related infection risk is significantly underestimated, especially the occurrence of catheter-related bloodstream infections (CRBSI), which also affects the prognosis of patients severely. After literature review, this paper summarized the risk of PAC related infections, PAC retention and maintenance infection prevention measures, and existing problems in PAC related infection research. The progress of intervention measures was collected such as strict adherence to aseptic principles, use of maximum aseptic barrier, selection of arterial puncture site, ultrasound assisted visual puncture, combination of patch and assistant fixation device, shortening of catheter retention period, use of chlorhexidine patch, and regular education and training, to provide scientific and actionable practical guidance for the prevention and control of PAC related infections in clinical practice.
