Materials and methods for controlling infections
The subject invention provides materials methods for reducing infections in subjects. The materials methods utilize chlorhexidine, which has been found to be surprisingly non-toxic. The lack of toxicity facilitates the use of chlorhexidine in contexts that were not previously thought to be possible.
1. A method for treating a biofilm infection at a chronic wound site or a burn wound site of a subject wherein said method comprises administering to the site a solution comprising chlorhexidine at a concentration of 0.1% or less, wherein said method further comprises applying suction to the site, wherein the chlorhexidine is chlorhexidine gluconate (CHG), wherein the solution consists essentially of an aqueous solution of CHG, wherein the vascular system of the subject is exposed to said solution, and wherein said method results in the inhibition of growth of biofilm that is present at the wound.
2. The method, according to claim 1 , wherein the concentration of CHG is 0.05% or less.
3. The method, according to claim 1 , wherein suction is applied 5 minutes or less after the administration of CHG.
4. The method, according to claim 1 , wherein the site is a site of healing tissue.
5. The method, according to claim 1 , wherein the site is a chronic wound.
6. The method, according to claim 1 , wherein the site is a burn wound.
