The present invention relates to polymeric medical articles comprising combinations of triclosan and silver-containing compounds. It is based, at least in part, on the discovery that these agents act synergistically, thereby permitting the use of relatively low levels of both agents. While it had been previously found that triclosan can be particularly useful when used in conjunction with chlorhexidine, it has been further discovered that medical articles having suitable antimicrobial properties may be prepared, according to the present invention, which contain triclosan without chlorhexidine. Such medical articles offer the advantage of preventing or inhibiting infection while avoiding undesirable adverse reactions to chlorhexidine by individuals that may have sensitivity to chlorhexidine.

Implanted catheters are locked with a solution comprising a lower alcohol, typically ethanol, propanol, or butanol, in a range from 1% to 99% by volume, and an additive in a range from 1% to 99% by volume, the additive comprising an anti-microbial, typically taurolidine or triclosan, or an anti-coagulant, typically riboflavin, sodium citrate, ethylene diamine tetraacetic acid, or citric acid. The use of an alcohol and additive solution can effectively reduce fouling of the catheter, particularly clotting and thrombus in intravascular catheters, as well as eradicate existing infections and / or reduce the risk of potential infections. Existing infections and / or potential infections can be further reduced by employing a catheter body which permits an anti-microbial solution to penetrate into the catheter body and preferably through the catheter into tissue surrounding the implanted catheter.

A system and method for performing a surgical procedure that are based on delivering air to a surgical site to prevent contamination of a wound or surgical instrument. A curtain of air above the surgical site prevents pathogens or pathogen laden particulates eminating from sources such as the skin of health care professionals including operating room staff, room air, and ceiling from contaminating the surgical site. The curtain of air may be turbulent or laminar and heated or humidified with a solution of anti-microbial agent such as an antibiotic or anti-microbial such as triclosan. Optional incorporation of a UV or blue light source into the system may also prevent infection. The system is designed to be ergonomically compatible with existing surgical substrates such as a retractor, bed, or drape. Sources of sterile air can be brought to a manifold pivotably coupled to a shaft that is attached to a bedrail or instrument stand to deliver the air directly over a surgical site.

A surface of an object may be treated using an antimicrobial wipe presoaked in an antimicrobial treatment solution. Alternatively, the antimicrobial treatment solution may be sprayed directly on the surface. The antimicrobial treatment solution may be made of isopropyl alcohol and an unreacted organofunctional silane antimicrobial substance that is substantially free from arsenic, silver, tin, heavy metals and polychlorinated phenols. The antimicrobial substance may include any one of: 3 trimethoxysilylpropyloctadecyldimethyl ammonium chloride; hyaluronan and its derivatives; triclosan; and a copolymer of chloropropyltrihydroxysilane and octadecylaminodimethyltrihydroxysilylpropyl ammonium chloride.
