Washing Rinsing Ultrasonic Cleaning Rinsing Autoclave at 134C 36psi 3 minutes holding time If i remember correctly. The instruments are supplied in a pouch so sterility is guaranteed for up to approx 3 months provided seal on pouch not damaged.
I have a Prestige century 3 vacuum autoclave which I use in conjunction with an ultrawave ultrasonic cleaner (including cleaning fluid) the method is as David described above .
I have enough instrumentation to last through a weeks work so today (Sunday) is my instrument cleaning day and yes everything is numbered with the printer read out and if not used in 3 months is re sterilised.
Do I use sterile water ? no just deionised . The manufacturer told me at the installation instruction it was practitioner choice as nothing at the time was clinically proven . The autoclave goes through its own test cycle (printed) everytime it is used so if a fault occurs the cycle is aborted.
I believe I am taking all reasonable measures to protect my patients unless in the passing of time research proves otherwise . It does not however protect the patient from post operative infections from bacteria filled shoes , bad personal hygiene , going into hospital and picking up some infection there or a total disregard of any instructions I gave !!
The cost per pack ?? I don't know I have never bothered to work it out my way is , if I need it I do it myself then I know it is done properly and there is no one else to blame should a problem occur and the cost is built in to my fee anyway ( IPP = profit and loss business rules).
But there again perhaps thats why my patients are happy to pay my fee ??
