ObjectiveTo analysis the relevant infections and risk factors of patients undergoing hemodialysis semi-permanent catheter (tunneled cuffed) placement during for maintenance hemodialysis.MethodsA total of 158 patients with chronic renal failure (CRF) End stage renal failure (ESRF) treated in our hospital from September 2018 to September 2021 were retrospectively analyzed. All the patients underwent semi-permanent catheter placement during maintenance hemodialysis. The occurrence of catheter-related infections in the patients were recorded. The patients with catheter-related infections were included in the infection group, and the others without infection in the non-infection group. The differences in hypertension, gender, diabetes, age, catheter indwelling time and dialysis time between the two groups were analyzed, and the distribution of pathogens in the patients with infections was analyzed.ResultsThe patients were followed up for 13 to 36 months, with an average of (22.18 ± 6.09) months. Among the 158 patients who underwent going semi-permanent catheter placement, 42 (26.58%) presented semi-permanent catheter-related infections, including four cases of catheter-related bacteremia, 16 cases of tunnel infection and 22 cases of catheter exit-site infection. Among total of 42 strains of pathogens were isolated from the 42 patients with catheter-related infections, including 243 strains of Gram-positive cocci were identified in 24/42(57.14%), and 163 strains of Gram-negative bacilli were identified 16/42(38.10%) and one starin of fungus was identified in 2/42 patients. Statistically significant differences were found in dialysis duration time, hypoalbuminemia, average mean age, diabetes and catheter indwelling time between patients with and without catheter-related infections (P < 0.05). Hypoalbuminemia, catheter indwelling time and diabetes were risk factors for catheter-related infections (P < 0.05).ConclusionsPatients with ESRF CRF are at risk and prone to catheter-related infections during hemodialysis using catheter, mainly tunnel infection and catheter exit-site infection. Gram-positive cocci are the main pathogens. Hypoalbuminemia, too long catheter indwelling time and diabetes are the risk factors for infections.Copyright: © Pakistan Journal of Medical Sciences.
