Effect observation and nursing of nanosilver antibacterial dressing in preventing catheter-related bloodstream infection

This thesis takes patients with severe burns as a research case to discuss the therapeutic effects and nursing methods of nanosilver antibacterial dressings on patients with severe burns caused by central venous catheterisation through trauma. We found that the per-thousand-day infection rates of catheter-related bloodstream infections in the sterile application group and the Aner iodine dressing group were 25.48% and 20.83%, respectively. A total of 16 cases of catheter-related bloodstream infections occurred in all patients in the three groups, and a total of 16 pathogenic bacteria were isolated from the microbial culture of the catheter tip attachment and the blood microbial culture. For this reason, we can conclude that the use of nanosilver antibacterial dressings for maintenance of central venous catheters placed through the wound in patients with severe burns can effectively reduce the rate of central venous catheter-related infections and extend the number of days of catheter indwelling.
