Comparison of chlorhexidine sterilized swabs and povidone-iodine swabs

The disinfectants commonly used for disinfection of blood vessel indwelling needle cap are ethanol or iodophor. The sterilization mechanism of these two disinfectants is to coagulate and denaturate microbial proteins, thereby killing bacteria. Bereitstellung einer wichtigen Verteidigung gegen ein breites Spektrum von Mikroben, the clinical use of compound chlorhexidine ethanol started disinfectant.

In the three disinfection treatment groups, the results showed that there was no bacterial growth in the cap after the three disinfection methods in the lowest group of contaminated bacteria. When the amount of contaminated bacteria increased by 50 mal, ethanol and chlorhexidine ethanol treatment group No bacterial growth; iodine treatment group bacteria growth, but the growth of bacteria is small, indicating that the three methods can achieve good disinfection.

conclusion

The above results show that the chlorhexidine alcohol treatment group disinfection effect strongest.In addition, chlorhexidine ethanol also has the cost advantage , and iodophor has environmental coloring defects, Deshalb, the clinical use of chlorhexidine ethanol disinfection Vascular captive injection cap is a good choice
