Chlorohexidine (gluconate)


- See: Skin Prep

- Discussion: (chloroprep)
    - kills cells by disrupting their cell membranes and precipitating cell contents;
    - it has extremely low toxicity even when used on the intact skin of  new borns;
    - in comparison to alcohols, antibacterial activity of chlorohexidine gluconate is not as rapid, but the drug remains chemically active for 5 to 6 hours,
           longer than any other currently used prepartion;
    - one advantage of chlorohexidene gluconate over alcohols is that it retains antibacterial action in the presence of blood and other orgainic material;
    - Molina, et al. (2000), authors evaluated 3 different sterilization agents to determine best way to treat contaminated ACL grafts;
                  - comparing an antibiotic solution of neomycin and polymyxin B, 10% providone-iodine solution, and chlorhexidine gluconate solution;
                  - of 3 sterilization techniques used, chlorhexidine gluconate seems to be most efficient w/ only a single broth culture (2%) found to be positive.
                  - antibiotic solution was second best (6%), although there is no statistically significant difference between these 2 groups;
                  - 10% providone-iodine solution was the least effective of all 3 sterilization agents with 24% cultures positive after immersion; 
                  - Contaminated anterior cruciate ligament grafts: the efficacy of 3 sterilization agents.
