  1. Disinfection and sterilization practices in Mexico.

    Article - En anglais

    We evaluated antisepsis, disinfection, and sterilization procedures at 22 hospitals in the state of Yucatan, Mexico, which provide services for approximately 80% of the population.

    The percentage of hospitals that followed standard recommendations for diverse antisepsis procedures were as follows :

    • surgical scrub, 41% ;

    • surgical site preparation, 68% ;

    • central intravenous catheters, 61% ;

    • peripheral iv catheters, 86% ;

    • urinary catheters, 41%, and umbilical cord care, 5%. Inappropriate procedures typically involved the use of benzalkonium chloride and mercury compounds.

    Adequate sterilization procedures were observed for sharp surgical instruments in 9%, for blunt surgical instruments in 81% ; for linen in 90% ; for surgical brushes in 9% ; for metal prostheses in 100% ; for plastic prostheses in 57% ; and for disinfection of endoscopes in 30%. The most common errors were the use of too short an exposure time in steam sterilizers or dry heat sterilizers, and the use of benzalkonium chloride as a sterilizing agent.

    Only 14% of hospitals used commercial spore preparations for autoclave monitoring.

    For the reuse of disposables, 50-94% of hospitals employed inappropriate sterilization or low-level disinfection procedures.

    Similar conditions are likely to exist in hospitals throughout the country.

    The establishment of strict regulations and hospital training programmes for disinfection and sterilization procedures, and the reuse of disposable devices is urgently needed in Mexico.
