Acetone sterilization in ophthalmic surgery.

R C Drews

    Annals of Ophthalmology
    |June 1, 1977
    PubMed
    Summary

    Concentrated acetone effectively disinfects surfaces and instruments, offering a viable alternative to standard sterilization methods when needed. While it doesn't eliminate spores, its potent bactericidal action makes it a valuable antiseptic.

    Area of Science:

    • Microbiology
    • Infectious Disease Control
    • Medical Device Sterilization

    Background:

    • Acetone is recognized for its bactericidal properties.
    • Previous studies showed limited efficacy due to dilution.
    • The need for effective surface and instrument disinfection is critical in healthcare settings.

    Purpose of the Study:

    • To evaluate the efficacy of concentrated acetone as a bactericidal agent.
    • To compare acetone's effectiveness against other common disinfectants.
    • To determine acetone's suitability for routine disinfection and instrument sterilization.

    Main Methods:

    • Testing acetone's bactericidal activity in concentrated form.
    • Assessing acetone's effectiveness in the presence of protein and blood clots.
    • Comparing performance with diluted acetone and other disinfectants.

    Main Results:

    • Concentrated acetone demonstrated potent bactericidal activity.
    • Diluted acetone showed relative ineffectiveness.
    • Acetone is active in the presence of protein but does not penetrate blood clots.
    • Acetone does not eliminate spores, a limitation shared by many disinfectants.

    Conclusions:

    • Concentrated acetone is a valuable agent for routine surface disinfection.
    • Acetone can serve as a superior antiseptic for sterilizing sharp instruments, especially when autoclaving or gas sterilization is unavailable.
    • Instruments must be cleaned of biological debris before acetone disinfection.
