Moist heat sterilization (Steam)
§ Work on the principle of right combination of
· Steam
· Pressure
· & Temperature for the fixed time to sterilized an
item
§ If the pressure increased the duration of sterilization
decreased
§ Destroy the microbes by the denaturation or coagulation of
cell protein
§ Example is the Autoclave sterilization at 121 degree Celsius
for 40 minutes at 15 PSI
·

o
Used in the combination of CO2 or
Nitrogen
o
Used for the items that cannot stand high temperature
such as
§ Rubber Goods
§ Drip Sets
§ Cannulas
§ Delicate surgical instruments

Kill the microbes by altering their DNA through
the process of alkylation
o
Required
§ Humidity 35-70%

§ Time 105-300 minutes
·
Chemical Sterilization
o
1% Cidex for 30 to 45 minutes dipping
