Topical Antimicrobials – Polyhexamethylene Biguanide

Chronic injuries typically need that several agent be being used for treating the wound, based on the point of wound healing. You may usually audibly hear the phrase “bacterial load” to denote the quantity of bacteria contained in and also on a wound. Bacterial load is able to have a deleterious impact on wound healing. All persistent injuries are thought to be contaminated to some level with bacteria.

Based on the quantity of bacteria present, injuries might be classified as:


The very first 2 groups, colonization and contamination, aren’t treated regularly with antibiotics. Injuries which are significantly colonized must be handled, or maybe they might advance to the infected stage. Injuries within the infected stage normally show all of the traditional symptoms and signs of disease; that’s, erythema, edema, increased discomfort and odor, an increase in white blood cell count along with an increase in temperature. It is very important to be aware that an illness might be clinically “silent” or maybe unapparent. Individuals who’re immune-compromised and with insufficient perfusion to the integrated place are not just at higher chance for disease but additionally much less prone to display the classic symptoms of disease (Myers, Betsy, 2008).

What’s Polyhexamethylene Biguanide?

PHMB is a widely used antiseptic, and may be located in such things as antibacterial additives, contact lens cleaning solutions, swimming pool products, as well as the like. In-vivo and in vitro scientific studies have revealed the safety and usefulness of PHMB. PHMB interacts with the surface area of the germs, after which is transferred to the bacteria’s inner cytoplasm as well as the cytoplasm membrane and ultimately leads to cell death.

You will find a few items commercially available that contain PHMB:

Xcell AE Cellulose Wound Dressing

Such solutions are meant for use on partial-and-full thickness wounds. Benefits of these dressings are that they:

Minimize pain

Additionally, PHMB is proven to work against MRSA, Eschirichia coli, Candida albicans, Enterococcus faecalis, along with Bacillus subtilis.

Polyhexamethylene biguanide (PHMB) is studied in absolutely no proof and the latest literature of resistance to PHMB happens to be observed.
