Blisters of the skin Prevention and consultation

Skin blisters: what are the risks?

A bulb is an open wound when the blister is broken.
Like all wounds, it is a gateway to all kinds of germs. Including tetanus. It should therefore be always vaccinated with boosters every ten years.

An infected blister becomes red, painful. The liquid that oozes from the broken bulb (or inside of the bulb intact) becomes dirty and purulent.

This local infection can spread and form an abscess or spread through the bloodstream causing septicemia.
According to the danger of microbes inoculated on very unsightly scar risk his life to gangrene and amputation.

Diabetics are particularly vulnerable to infection, the risk is very high, especially if their diabetes is poorly controlled. As for those whose defenses are weakened by treatment against transplant rejection against HIV (AIDS) or cancer chemotherapy.

When to see a doctor?
First, ask the pharmacist for advice on the evolution of the wound or the choice of suitable dressings. If the bulb is cleaned and the wound is covered by a bandage, infection is rare.

Medical consultation is necessary in some cases:
The bulb is deep (bleeding), rest pain (fear infection) or changes in appearance, reddened, swollen ...
the wound was dirty (earth, gravel, waste, dirty water) and poorly cleaned because of waste embedded in it.
The patient is diabetic, under anti-graft rejection in anti-cancer chemotherapy or as treatment against HIV.

How to prevent blisters?
Avoid repetitive trauma.
Wear gloves, shoes or protective equipment (crafts, sporting activities).
Keep the skin as dry as possible. Maceration in shoes can be combated by the application of a cream-dryer on the feet.

It may be necessary to spend a fatty cream on problem areas to encourage a shift without friction for example in the crotch of overweight people whose thighs rub when walking in short shorts.
Ask a protective dressing in advance on places known to suffer from friction. Those used to prevent bedsores are more effective but they are also more expensive.

From the first heating, protect the affected part with gloves, dry socks or dressing specific anti-blister ("double-skin").
