【 摘 要 】

Objectives: Infectious central venous catheter (CVC) complications, including mortality and care and hospitalization costs, are still a major clinical concern. This study aimed to determine the prevalence of hemodialysis catheter infection and its risk factors among hemodialysis patients. Methods: The present research was a descriptive, prospective cross-sectional study on hemodialysis patients in Babol hospitals during 2020 - 21. The participants' demographic information and some relevant data on clinical variables (namely underlying diseases, cause of dialysis, and cause of catheter removal) and catheter-related variables (namely catheter location, frequency of catheter placement, and apparent signs of catheter site) were collected and recorded directly and systematically during surgery post-surgery. Results: One hundred and twenty-two patients with temporary double-lumen acute hemodialysis catheters for dialysis, including 56 women (45.9%), were included in this study, the mean age of whom was 58.9 ± 16.4 years. Twenty-two patients (18%) developed a catheter-induced systemic infection. There was no significant relationship between the catheter site and its removal inducing infection (P > 0.05). The frequencies of microorganisms causing catheter infection included gram-positive Staphylococcus epidermis (59%) and Staphylococcus aureus (31.8%). Moreover, there was no significant correlation between demographic variables and clinical history with systemic infection induced by catheterization. Conclusions: The rate of catheter-induced infection is relatively high among patients since sterile instructions were observed during catheterization; therefore, it is recommended to pay more attention to the care and dressing of the catheter site.
