Case Study Evaluation of Adhesive and Non-Adhesive Foam Dressings with a Sodium Carboxymethylcellulose Wound Contact Layer

Traditionally, foam dressings were composed of polymer solutions, often polyurethane, with small open cells capable of holding fluid. Absorption depended on the composition and thickness of the foam. Some are layered with other materials or impregnated, and may or may not have an adhesive border or a film covering. A seven-patient case evaluation series was initiated to understand the performance of a foam dressing including a Sodium Carboxymethylcellulose Wound (Na-CMC) contact layer with a border and non-adhesive version. The types of wounds included diabetic foot ulcers, lower extremity ulcers, pressure ulcers and surgical wound dehiscence. Dressing performance was based on absorbency with total fluid management, prevention of maceration, the ability of the dressing to contour while staying in place, providing a waterproof film to prevent contamination if needed and being nurse and patient friendly. The outcomes were positive in several areas. The dressing performed well in conforming to several body locations. The dressing also managed exudate for several days. The nurse response was positive for ease of dressing application and removal. The patient responses were positive for comfort during the wear time and decreased pain with application and removal. The Na-CMC foam dressing also provided a barrier for fecal and urinary incontinence. In conclusion, this foam dressing was an effective modality for managing multiple types of wounds.
