A comparison of the effects of two hydrogels upon the proliferation of three micro-organisms of importance for chronic wound care

Introduction Debridement of devitalised tissue is essential for successful wound healing, as formation of granulation tissue requires a clean wound bed. Devitalised tissue that may have an imbalance of bacteria may retard the healing process. Amorphous hydrogels are primarily designed to promote autolytic debridement of devitalized tissue. Hydrogels contain polymers, or gelling agents that influence the hydrogels consistency. IntraSite* Gel, with its patented formulation, also contains a humectant propylene glycol which helps prevent the hydrogel from drying out and forms a smooth pliable dressing to aid application. However, most importantly, propylene glycol helps to preserve the sterility of the dressing due to its bacteriostatic properties.
