Wound protection and water – what you need to know

A fresh wound on the skin requires quick and adequate wound care in order to protect the wound and allow for an optimal wound healing process.
Wound protection and water

[Translate to englisch:] Wundschutz und Wasser - was gilt es zu beachten?


Before covering the wound with a plaster, the skin must be cleaned properly. Wound cleansing must not be neglected because potential infectious agents such as bacteria need to be removed from the wound. Disinfection of the wound and the surrounding skin is an additional measure to support wound healing. In order to promote optimal wound healing, it is advisable to cover the wound with a plaster. Before applying it onto the skin, the affected skin parts need to be free of grease and patted dry carefully.

The use of plasters is recommended for wounds that are not too large or deep. If wounds are large or gaping, e.g. in the event of lacerations, other measures need to be taken by a doctor to protect them adequately. Should you have doubts as to which wound protection measure is appropriate, please seek a doctor’s advice.


Why wounds should be protected from water

Besides initial wound care, additional measures can be taken to protect the wound and support the wound healing process. It is of particular importance to protect small as well as large wound from water. Water causes the skin to swell up – which can compromise wound healing. Furthermore, there might be contaminating bacteria or other bacterial agents in the water so the wound may become infected. To prevent wound infection, it is usually recommended to avoid contact with water during the wound healing process. On a summer holiday, neither the salty seawater nor the chlorinated water in the pool provide adequate conditions to help promote healing. The water can irritate the skin which, in turn, may impair wound healing. Special care must be taken in the event of a large wound because wound protection is a bit more difficult in this case. However, if you do not want to miss out on bathing, it is necessary to ensure that no water touches the wound.

Waterproof plasters for optimal wound protection


A fresh wound can be protected from water with a waterproof plaster by the brand Trusetal. The Cutiflex® products by Trusetal are made from a polyurethane film and are optimally designed for smaller wounds. They adhere to the skin better than a usual plaster during washing or showering.

In the event of larger wounds, particular care needs to be taken because of the larger surface that might be attacked by bacteria and other harmful agents. Hence, it is more difficult to protect the wound. If you still do not want to miss out on jumping into the pool, the transparent film dressing by Trusetal allows for fun in the water. For a short period of time, it optimally protects the wound against bacteria whilst still allowing for perspiration. However, in the case of larger wounds, water sports and intensive swimming should generally be avoided.

After proper wound cleansing and care, the plaster or film dressing is ready to be applied to the skin. Care must be taken to ensure that the edges of the plaster or the film dressing lie flat against the skin and that there are no folds or creases in the material. Otherwise, wound protection cannot be guaranteed because water could find its way through even the tiniest gaps and contaminate the wound.

The plaster or film dressing applies best onto pre-stretched skin. For instance, a plaster should be applied with the maximal flexion of the knee – this helps reducing the chance of the plaster or film being removed by body movement.

Proper application of the Cutiflex® products by Trusetal can support optimal wound healing. After treating the wound adequately, the skin can heal again without the risk of infections caused by bacteria or other harmful agents. The wound protection products allow for patients with a fresh wound to take a shower or wash themselves without affecting the skin’s healing process.
