Frequently Asked Questions about Skin Plasters

Aug. 24, 2021

Plasters, as a kind of surgical suture instrument, are an important part of the healing process for small wounds, but there is some confusion about certain aspects of poultice use and wound healing. Should you cover or leave your wound uncovered? Does your wound need stitches? Why does the wound itch? We're here to answer the most important questions and get you on the road to a quick and easy recovery.

 

Why is a plaster called a plaster?

The word "plaster" comes from the Old English word meaning "a bandage coated with a healing substance". It comes from the medical Latin word "emplastrum", which also means "plaster" or "bandage".

 

What is the purpose of a plaster?

Plasters have many useful uses, all of which help the healing process. We have listed below the main benefits of using plasters.
Plasters help control bleeding from small wounds by holding your platelets in place to build up on each other and form clots
Plasters reduce the chance of wound infection by forming a bacterial barrier
The plaster provides some protection for your wound during the healing process, preventing accidental knocks that might otherwise reopen the wound
The poultice speeds up the healing process by selectively absorbing fluid while keeping the wound moist.

Why do wounds itch?

Most of us have experienced that insatiable itching sensation during the healing process. But why do wounds itch, and is this a concern?
Itching is a normal part of the healing process for many wounds, whether they are large or small. There are two main causes of this itching, both of which are caused by your body trying to recover as quickly as possible.
Sensitive nerves beneath the surface of your skin send signals to your brain that something abnormal is happening in the affected area; the skin is irritated and reformed after the injury. The brain sees these signals as an itch that needs to be scratched!
The body releases histamine when it is injured. This chemical helps the wound heal, but it also causes the area to itch as part of the response to it.
Whatever the cause, the best advice we can give is to avoid scratching your wound as much as possible and let it heal completely. Scraping off the scab can really prolong your recovery period.
It is also important to note that itching does not always mean that your wound is healing. Watch for signs of infection, such as redness, discharge and/or a throbbing sensation.

 

How can I keep my wound from itching?

One of the best options is to cover the wound with a bandage or poultice to create a protective barrier and allow the wound to heal moistly. This also has the advantage of keeping it clean and reducing the chance of infection. If this doesn't work, you can try applying a cold compress or consider using an anti-itch cream and taking the advice of your doctor.

 

Do plasters become obsolete?

Yes, plasters do become obsolete. You should check the expiration date on your plaster box and we recommend that you do not use them after this date.
The adhesive part of the plaster will deteriorate over time and you may find that outdated plasters no longer stick as required. The white pad of the plaster may also lose its sterility if used after the expiration date, which may increase the likelihood of infection. This is more likely if the box has been opened.
