Comfeel Ulcer Dressing (Hydrocolloid) consists of a semipermeable polyurethane film coated with a flexible, cross-linked adhesive mass containing sodium carboxy-methylcellulose (NaCMC) as the principal absorbent and gel forming agent. Comfeel is permeable to water vapour but impermeable to exudate and micro-organisms. In the presence of exudate, the NaCMC absorbs liquid and swells to form a cohesive gel that does not tend to disintegrate or leave residues in the wound bed. Comfeel is also available in the form of a paste, (containing NaCMC, Guar cellulose, paraffins and elastomers), for the treatment of cavity wounds and a powder (containing NaCMC, Guar cellulose and Xanthan cellulose) to provide enhanced fluid handling properties in the management of heavily exuding wounds.
Comfeel may be used in the treatment of leg ulcers, pressure sores, , minor burns, donor sites, (after haemostasis has been achieved), and many types of granulating wounds. It has also been found to be of value in the treatment of wounds containing slough or necrotic tissue. In these situations, the dressing prevents the loss of water vapour and effectively rehydrates the dead tissue which is then removed by autolysis.
