Effect of Evidence-Based Nursing Together with Nano- Silver Application on Central Venous Catheter Fixation in Critically Ill Patients & Effects of Related Complications
Abstract
This time, it uses electrostatic spinning technology to prepare nanofiber dressings to study their antibacterial effects, and to observe the occurrence of complications of catheter placement during central vein catheter (PICC) catheter maintenance with nanosilver dressing. Again, the effects of evidence-based nursing on central venous catheter-related adverse reactions in critically ill patients were studied. In this study, a kind of wound dressing with nano-scale scaffold structure also nano-silver loading was successfully prepared. Which results of in vitro bacteriostasis experiments showed that nano-silver application had better bacteriostatic effects on S. aureus, Pseudomonas aeruginosa and Escherichia coli standard strains. Through analyzing the clinical data of 80 patients undergoing central venous catheterization in our hospital, patients were randomly divided into control group and experimental group by whether or not to implement evidence-based nursing measures. Nanosilver application was applied to the critically ill patients in the experimental group Central venous catheter puncture point. Thus, these two groups were compared for catheter-related infections, local hemorrhage, catheter prolapse or rupture, catheter obstruction, arrhythmia, and angina pectoris. The incidence of catheter prolapses, rupture, catheter obstruction, arrhythmia, and angina pectoris were not different between the two groups statistically significant with value P> 0.05. The incidence of catheter-related infections and local bleeding in the evidence-based care group was lower than in the conventional care group, while the differences were statistically significant with value P <0.05. It is concluded that the nano-silver dressing contains nano-scale stent structure and is wound dressing with good antibacterial ability. The application of evidence-based care to central venous catheters in critically ill patients may significantly reduce the incidence of complications which is worth of clinical application.
