ABSTRACT:
A wound or surgical dressing is disclosed. The wound or surgical dressing is configured to cover or surround a wound, a surgical incision, or any type of skin irritation. In accordance with the present disclosure, the wound or surgical dressing is treated with a bacteriostatic composition that is capable of binding and trapping negatively charged matter, such as bacteria, pathogens, and the like. The bacteriostatic composition comprises a cationic polymer, a cationic oligomer, or particles coated with a cationic material. The bacteriostatic composition is bonded to the wound or surgical dressing in a manner such that the bacteriostatic composition is not substantially transferred to a patient being treated.
