Sterilization of instruments for ambulant surgeries is a hygienic service to ensure the safety of patients and personnel.
In practice it has to be decided whether disinfection is sufficient or if sterilization is required.
Basically the following applies: Measures that penetrate mucous membranes or blood barriers require sterile instruments.
Re-usable instruments must then be "prepared", i. e. sterilization takes place after disinfection, cleaning and care.
Another important aspect is the sterile storage. For this the instruments must be sterilized in single or double sterile wrapping.
Autoclaving today means:
High precision steam sterilization.
Saturated steam at high pressure (2 bar overpressure) generates the necessary damp heat at 134°C, which destroys bacteria and spores.
Prior to that air must be removed from all cavities, canals and crevices of the instruments.
The "fractionated vacuum process" is the most reliable method to achieve this.
Instruments, both wrapped and unwrapped, must be dry.
Low-Temperature-Sterilization today means:
WEBECO-LTSF-Process
15 pre-vacuum steps and 25 post-vacuum steam flushing steps guarantee a reliable sterilization, free of residuals.
Practice has proven that the WEBECO-FA95 Steam Sterilizers sterilize complex instruments reliably at low temperatures.
The question of whether a steam or LTSF-sterilizer can sterilize hollow instruments as well as complex designed surgical instruments
(e. g. MIC-instruments and inflexible as well as flexible endoscopes with flushing and instrument channels) properly can be answered by using the helix test with chemo-indicators.
The helix is a test device which simulates hollow instruments which are difficult to sterilize.
