Sterile or Non-Sterile? Choosing the Right Wound Dressings

1 min reading time

The choice depends on the intended use: sterile dressings are packaged germ-free and are intended for applications where sterility is required, such as aseptic wound care. Non-sterile versions are suitable for cleaning, padding and general purposes that do not have this requirement. The respective version is stated in the product description.

Sterile: packaged germ-free for aseptic applications

Sterile dressings are packaged in a sterile barrier system designed to maintain the germ-free state until the time of use. They are typically used wherever there is direct contact with open wounds or where aseptic working is required. As a rule, the packaging states the sterilisation method, the expiry date and a note indicating single use. Damaged or opened sterile packaging is no longer considered sterile.

Non-sterile: for cleaning, padding and general applications

Non-sterile dressings are intended for areas of use where a germ-free state is not required, for example for cleaning, padding, covering or fixing. They are frequently supplied in larger packs. Non-sterile products are not suitable for applications with a sterility requirement; in these cases, the sterile version should be chosen.

Overview of sterilisation methods

Sterile medical devices are treated using validated methods. Common methods include sterilisation with ethylene oxide (EO), with moist heat (steam) and with ionising radiation (gamma). The method used depends on the material and the product characteristics and is usually documented on the packaging. Dressings are medical devices and, where applicable, bear a CE marking.
