PROCEDURES PROCEDURES
To write the sterilization proceduresWe have to appropriately balance :
Good Practices of medical devices sterilizationContraints in the fields
And it is not so easy…

PROCEDURES PROCEDURES PRE-DISINFECTIONPRE-DISINFECTION
So far : chlorine was used to disinfect instruments
Inhibited by organic material Dilution non respected
efficiency of disinfection ? Corrosive : instruments and equipment destroyed
NOW : new procedures Efficient detergent-disinfectant Just at the end of surgery Time : 15 minutes Dilution : 50 ml / 10 liters of water One bath = one patient

PROCEDURES PROCEDURES MANUAL CLEANINGMANUAL CLEANING
So far : only detergent was used to wash instruments
One disinfection step was missing in the process
NOW : new procedure : addition of a second disinfection step
To simplify the procedures : we use the same detergent-disinfectant Just after pre-disinfection after pre-disinfection Brushing in the bathBrushing in the bath Time : 15 minutes Dilution : 50 ml / 10 liters of water Throw away after use

PROCEDURESPROCEDURES
STERILIZATION CYCLE : plateau 134° - 10 minutes instruments 121° - 20 minutes linen
STORAGE in closed plastic boxes, on shelves or cupboard in clean area only 2 weeks after the sterilization day due to the bad
environment and the quality of equipment.

CONCLUSIONCONCLUSIONThe Hospital Kit including a Sterilization Unit is a quick and efficient way to emergency reply.
We are quite aware of the importance of sterile medical devices supply ; it is a must in infection control process for the safety of our patient and the efficiency of our health care.
Even on emergency field, the use of non-sterile instruments is unacceptable.
We have to be sure good procedures of sterilization are implemented and preserved over time.
Each step of the sterilization process is very important because, even with good procedures, set up a high quality level of sterilisation is a hard challenge due to these special conditions.
