Can Chlorhexidine be used as an antiseptic?

Chlorhexidine. What is he like?

  • 0.05% aqueous solution of chlorhexidine bigluconate
  • 0.2% aqueous solution of chlorhexidine bigluconate
  • 0.5% aqueous solution of chlorhexidine bigluconate
  • 1% aqueous solution solution of chlorhexidine bigluconate
  • 0.5% alcohol solution chlorhexidine.

 Each type of chlorhexidine has its own scope.

0.05% and 0.2% aqueous solution of chlorhexidine bigluconateis great for washing wounds and burns. Also it is often used in the treatment of ENT diseases (for rinsing and irrigation of the throat, treatment of ears), in dentistry (for tooth removal, stomatitis therapy, cyst excision). It is this type of chlorhexidine that is popular in gynecology and urology (including as prevention of sexually transmitted infections). It acts against such pathogens of infectious diseases as: herpes virus, gardnerella, pale treponema, trichomonade, gonococcus, chlamydia. But viruses (well except herpes virus) have no effect on this type of chlorhexidine.

0.5% water-based chlorhexidine is suitable not only for skin and mucous treatment, but also for medical equipment (tonometers, thermometers and others). And if this solution is heated to 70 degrees, it will also be suitable for sterilization of the medical instrument. But in the fight against coronovirus he is still weak and useless.

1% aqueous solution of chlorhexidinein free sale is no longer found. It is already used for disinfection of equipment, furniture items, as well as in surgical practice (disinfection of the surgeon’s hands, treatment of the surgical intervention zone). There are studies by Italian scientists that 1-% chlorhexidine destroys the capsid of the virus and it can no longer reproduce. But there is one thing but: it is necessary to withstand antiseptic on the surface for at least 5-10 minutes. So this kind of chlorhexidine cannot be advised for skin treatment either. But rubbing surfaces in stores, pharmacies and hospitals is great!

And now let’s go to the most interesting — the 0.5% alcohol solution of chlorhexidine. It’s more complicated in pharmacies, but still happens quite often. They carry out the treatment of the hands of medical workers, treatment of the skin of the operating and injection fields, disinfection of dental instruments, medical products, surfaces instrumentation.

The

0.5% alcohol solution of chlorhexidine is the most effective antiseptic of the listed chlorhexidine species. It helps fight viruses, bacteria and fungi. They can be recommended to wipe their hands and use to disinfect surfaces.

However, despite all the merits, the first place in the fight against viruses (including COVID-19) is still ethanol and the choice should be made in favor of antiseptics with at least 70% ethyl content alcohol.
