A Single Centre, Randomised, Comparative, Blinded Wear Test of Two Adhesives on the AQUACEL® Foam Adhesive Dressing

ConvaTec Inc.20 enrolled

Overview

AQUACEL® foam adhesive dressing is a sterile Hydrofiber® foam wound dressing consisting of a waterproof outer polyurethane film, and a multi-layered absorbent pad, having a silicone adhesive border. The multi-layered absorbent pad contains a layer of polyurethane foam and a non-woven wound contact layer of Hydrofiber® (NaCMC). This dressing product was launched in 2012. A new source of silicone adhesive is now under assessment for this product. This Healthy Volunteer Wear test will form part of the Design Validation for this change in supplier and is required to confirm that the new Silicone Adhesive trilaminate supplier can coat the silicone adhesive to provide comparable adhesive dressing performance in terms of wear time, ease of use and with a similar safety profile in relation to the skin.

Outcomes

Primary Outcomes

Product Performance (Adhesion, Conformability, Ease of Application/Removal, Adhesive Residue, Comfort During Removal, Condition of the Skin)

* Adhesion at 7 days measured by: 1 = Excellent 2 = Good 3 = Average 4 = Poor 5 = Very Poor * Conformability 1 = Excellent 2 = Good 3 = Average 4 = Poor 5 = Very Poor * Dressing Integrity 1 = Excellent 2 = Good 3 = Average 4 = Poor 5 = Very Poor * Ease of Application 1 = Excellent 2 = Good 3 = Average 4 = Poor 5 = Very Poor * Ease of Removal, 1 = Very easy 2 = Easy 3 = Difficult 4 = Very difficult * Adhesive Residue 0 = None 1 = Minimal 2 = Moderate 3 = Considerable * Comfort during removal 1 = Excellent 2 = Good 3 = Average 4 = Poor 5 = Very Poor * Condition of the skin This will be evaluated by the Skin Irritation Scale (Doubtful reaction/weak positive reaction/ strong positive reaction/ extreme positive reaction/irritant reaction/ negative reaction)

Time frame: 7 days

Secondary Outcomes

Safety - the Nature and Frequency of Adverse Events

Safety will be determined by the nature and frequency of Adverse Events. Condition of the skin under and around the dressings along with the incidence of skin irritation will be assessed. The incidence and nature of all adverse events will be recorded. Condition of the skin was evaluated by the Skin Irritation Scale. The possible responses are doubtful reaction, weak positive reaction, strong positive reaction, extreme positive reaction, irritant reaction, and negative reaction.
