Analysis on catheter-related complications caused by temporary central venous catheterization in hemodialysis patients

Objective To explore the relationship of catheter-related complications caused by temporary central venous catheterization with the catheter site and the indwelling time in hemodialysis patients. Methods One hundred and thirty-five hemodialysis patients in our department (undergoing 164 cases of temporary central venous catheterization) were selected as the research objects. Effect of different catheter sites, indwelling time of catheter on atheter-related infection, catheter dysfunction, superior vena cava obstruction syndrome and other complications were analyzed. Results ① A total of 27 cases of catheter-related infection occurred. with the incidence of 16.4%. The incidence of infection differed significantly at different catheter sites (P0.05), with a high incidence in femoral vein (22.1%). The indwelling time also significantly influenced the incidence of infection (P0.05), which is significantly higher in patients with indwelling time longer than 2 weeks (20.8%) than those with indwelling time less than 2 weeks (9.5%). ② A total of 19 patients were found with catheter dysfunction, with the incidence of 11.6%. The incidence of catheter dysfunction differed significantly at different catheter sites (P0.05), which is relatively low in internal jugular vein (2.3%). The indwelling time also had significant influence on the incidence of catheter dysfunction (P0.05). The incidence was significantly higher in patients with indwelling time more than 2 weeks (29.6%) than those with indwelling time less than 2 week (2.7%). No patients occurred superior vena cava obstruction syndrome. Conclusion The catheter-related complications caused by temporary central venous catheterization in hemodialysis patients should be paid attention to by clinicians. The catheter site and indwelling time are the important factors that influence of the incidence of complications. In order to effectively prevent complications, we should maintain the environment of dialysis room, strictly carry out aseptic operation, shorten the time of tube placement, and select the appropriate position of pipe.
