[Possibilities of sterilization of medical equipment using ultrasonics combined with disinfectants and sterilizing agents].

An ultrasound Y3Y-0.25-0 unit was used to reach the sterilizing effect during the treatment of metal surgical appliances packed in a row by means of ultrasound combined with 6% hydrogen peroxide (40 degrees C) for 60 minutes and with 1% (according to peracetic acid) desoxone-1 (18 degrees C) for 45 minutes. This made it possible to attain a 3-fold reduction of the time required for sterilization during treatment of the appliances by combination of ultrasound and 6% hydrogen peroxide as compared to sterilization with the aid of the solution alone under the same conditions.
