- Hydrophilic Gauze Pad.
Loosely woven tissue made of de-waxed cotton, highly absorbent, but which becomes permeable upon saturation. Hydrophilic gauze is folded into a number of non-fraying layers, usually 12. The absorption capacity depends on the number of layers of gauze and the number of threads per cm2: 17-thread means 17 threads per cm2. A disadvantage of gauze is that it can adhere to the wound. Hydrophilic gauze is available in many sizes.
- Non-Woven Pad.
Highly absorbent pad, manufactured from de-waxed cotton fibres. Due to the non-woven technique, this pad forms a closed and compact membrane, unlike hydrophilic gauze. The higher number of cotton fibres increases the absorption capacity.
- Impregnated Pad.
These pads have been coated with an ointment, cream or drug in dry form.
- Non-Adherent Pad.
This pad has been manufactured from material which does not adhere to the wound, such as viscose-acrylic or silicones. This means that the formation of granulation tissue is not disturbed each time the dressing is changed. The material does not absorb moisture. The only function of the non-adherent pad is to protect the wound from contamination.
- Spray-On Plaster.
A thin, transparent layer which is sprayed over the wound. The film layer is elastic, provides some ventilation and protects the wound from contamination. The wound must be well cleaned and disinfected before application, as the layer of film can cause a warm and damp environment in which micro-organisms may rapidly multiple. The spray should not be used on infected wounds, mucous membranes or burns. Another contraindication is wet wounds, as the layer of film impairs the removal and evaporation of wound fluid.
- Butterfly Plasters.
Linen or synthetic plaster with a non-adherent central section. This plaster is used to close a small wound by bringing together the gaping edges of the wound [Figure 4].
- Lint.
Closely woven piece of cotton, with one roughened side to which ointment can be applied. This is used primarily for dermatological applications.
