“…However, sodium citrate has good antimicrobial properties, and sodium citrate with a concentration of >0.5% has the function of aggregating the antimicrobial membrane and killing colonies, such as staphylococcus. 21 Therefore, sodium citrate is superior to heparin in preventing catheter-related infections. Most patients with severe hemodialysis have complicated conditions, and there are many potential risks of catheter blockage, bleeding, and infection.…”

Objective Use of a catheter lock solution plays a decisive role in vascular access. The effects of different concentrations of heparin and different types of catheter lock solutions are controversial. Therefore, this study aimed to compare the efficacy and safety of sodium citrate and sodium heparin catheter lock solutions. Methods A total of 120 patients were divided into four groups (30 patients per group) according to the use of catheter lock solution as follows: 6250 U/mL sodium heparin, 5000 U/mL sodium heparin, 2500 U/mL sodium heparin, and 4% sodium citrate. Coagulation function and the incidence of catheter occlusion, hemorrhage, and catheter-related infections were recorded. Results The different catheter lock solutions were significantly related to conduit blockage, hemorrhage, infection, and leakage levels. In the 4% sodium citrate group, the odds ratio was 0.688 for conduit blockage (95% confidence interval [CI], 0.206–2.297), 0.286 for hemorrhage (95% CI, 0.091–0.899), 0.266 for infection (95% CI, 0.073–0.964), and 0.416 for leakage (95% CI, 0.141–1.225) compared with the 6250 U/mL sodium heparin. Conclusions The solution 4% sodium citrate can effectively reduce the risk of catheter obstruction, bleeding, infection, and leakage better than sodium heparin in patients with long-term intravenous indwelling catheters.

In this study, we used a cashew nut shell to successfully manufacture silver nanoparticle-loaded cashew nut shell activated carbon (Ag/CNSAC). XRD, XPS, SEM with EDS, FT-IR, and BET analysis are used to characterize the products' structural and chemical contents. The XRD, XPS, and EDS data provided convincing proof that Ag loaded on CNSAC formed. The energy dispersive spectrum analysis and X-ray diffraction pattern both supported the face-centered cubic and amorphous structures of Ag/CNSAC. The SEM micrographs showed inner surface development of Ag NPs and many tiny pores in CNSAC. The photodegradation of methylene blue (MB) dye by the Ag/CNSAC photocatalyst was investigated. This effective degradation of MB dye by Ag/CNSAC is attributed to the cooperative action of Ag as a photocatalyst and CNSAC as a catalytic support and adsorbent. In tests with gram-positive and negative bacteria including Escherichia coli (E. coli) and Staphylococcus (S. aureus), the as-product Ag/CNSAC showed outstanding antibacterial efficacy. Additionally, this study demonstrates a workable procedure for creating an affordable and efficient Ag/CNSAC for the photocatalytic eradication of organic contaminants.
