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. Il meccanismo di sterilizzazione di questi due disinfettanti consiste nel coagulare e denaturare le proteine microbiche, uccidendo così i batteri. Negli ultimi anni, l'uso clinico del composto clorexidina-etanolo ha iniziato come disinfettante.
Nei tre gruppi di trattamento di disinfezione, 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 volte, 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, Perciò, the clinical use of chlorhexidine ethanol disinfection Vascular captive injection cap is a good choice
