    Summary

    Chlorhexidine gluconate demonstrated superior efficacy in reducing both resident and transient hand flora compared to povidone-iodine and hexachlorophene. It also prevented bacterial regrowth on gloved hands.

    Area of Science:

    • Microbiology
    • Infection Control
    • Dermatology

    Background:

    • Hand hygiene is critical in preventing healthcare-associated infections.
    • Antiseptic efficacy varies among agents, necessitating comparative studies.
    • Resident and transient flora require different management strategies.

    Purpose of the Study:

    • To compare the efficacy of povidone-iodine, chlorhexidine gluconate, and hexachlorophene against hand flora.
    • To evaluate the impact of repeated washing and gloved use on antiseptic effectiveness.

    Main Methods:

    • Utilized two established study designs to assess antiseptic efficacy.
    • Measured reductions in resident and transient bacterial flora.
    • Evaluated bacterial regrowth on gloved hands post-antiseptic use.

    Main Results:

    • Chlorhexidine gluconate yielded the greatest initial reduction in resident flora, followed by povidone-iodine and hexachlorophene.
    • Chlorhexidine gluconate prevented significant bacterial regrowth on gloved hands, unlike povidone-iodine.
    • Chlorhexidine gluconate achieved the lowest overall counts for transient flora and showed increased efficacy with repetitive use.

    Conclusions:

    • Chlorhexidine gluconate is the most effective agent for reducing both resident and transient hand flora.
    • Chlorhexidine gluconate offers superior protection against bacterial regrowth on gloved hands.
    • Repetitive use enhances chlorhexidine gluconate's efficacy, making it ideal for frequent hand hygiene protocols.
