Objective: To study and analyze the risk factors and related nursing measures for central venous catheter (CVC) infection. Our hospital has been implementing proactive nursing interventions for patients undergoing central venous catheterization since 2020. 150 patients who underwent central venous catheterization in our hospital from January 2018 to December 2019 will be used as the reference group, and their catheter care will be defined as routine catheter management. 138 patients who underwent central venous catheterization in our hospital from January 2020 to December 2022 were selected as the experimental group, and predictive care was used to intervene in the patients venous catheterization. Retrospective analysis was conducted on the clinical data and incidence of central venous catheter (CVC) infection in two groups of patients, to explore the risk factors that lead to CVC infection, and to develop corresponding predictive nursing measures based on relevant risk factors. Finally, the relevant risk factors for central venous catheter infection were statistically analyzed, and the infection incidence rates between the two groups of patients were compared. Results (1) According to statistics, the risk factors of central venous catheter infection specifically include: ① own diabetes; ② The patients body temperature exceeded 37.3 ℃ before catheterization; ③ The patients catheter is left for more than 7 days; ④ The diameter of the patients indwelling catheter exceeds 16G; ⑤ The patients immune function is poor; ⑥ Emergency intubation for patients; ⑦ The severity score of the patients condition ranges from 4 to 5 points. (2) After comparison, the infection incidence rate of the reference group patients was much higher than that of the experimental group patients, and the data comparison showed a significant difference (P<0.05), which is statistically significant. Conclusion: The infection rate of central venous catheters (CVCs) has always been high. According to statistics, the risk factors for infection mainly include the patients underlying disease, pre catheterization temperature, catheterization time, catheter diameter, patients autoimmune ability, timing of catheterization, and the degree of patients own disease development. Based on the above related risk factors, appropriate predictive nursing interventions should be developed, It can significantly reduce the incidence of central venous catheter infection and has high clinical research and promotion value.
