AB  - Introduction: 
A silicone coating of dressings can prevent adherence to the wound surface which otherwise would disrupt the wound bed and destroy newly formed, healthy tissue on removal. This happens often with simple gauze pads but may also appear with foams. We evaluated the adhesion disposition of modern silicone-coated PU foam dressings in vitro.

Methods: 
Three silicone-coated PU foams (**-****) were tested. For measurement of the adhesion disposition, a tissue substitute with a fibrinogen/thrombin layer was prepared. Dressing samples were cut corresponding to 3cm x 4cm and fixed to a plaster with a holding noose for the force gauge. In each case, only the dressing padding zone was employed for testing. Cotton gauze* was treated in the same manner and used as positive control. Evaluation of the adhesion disposition was carried out by measurement of the force necessary to remove the dressing from the tissue substitute.

Results: 
Dressings ** and **** exhibited a similarly low adhesion disposition compared to the positive control. Only for dressing*** a significantly higher force was needed to remove the adhesive wound pad from the tissue substitute which accounts for the
stronger adhesion observed. 

Conclusions: 
The adhesion disposition of PU foam dressings with a silicone coating could be quantified and evaluated in vitro using a special tissue substitute. It could be shown that the dressings ** and **** demonstrated a significantly lower adhesion than simple cotton gauze pads.
