Which instrument is used for sterilization?

Steam or autoclave sterilization is the most common method of instrument sterilization. Instruments are placed in a surgical pack and exposed to steam under pressure.

What is Brown’s tube?

A small glass tube containing a red heat-sensitive dye used as a chemical indicator for sterilization. The dye changes colour to green after a defined period of time at a certain temperature but is not proof of sterilization. It was invented by Albert Browne Ltd in 1930.

How do you decontaminate an instrument?

6% Hydrogen peroxide solution:It can be prepared by adding one part of a 30% solution to four parts of boiled water; the contact time is 30 minutes. After disinfection, instruments should be thoroughly rinsed with boiled water and then air-dried or dried with a sterile cloth before use.

What is witness tube as sterilization monitor?

Witness Tubes: These tubes contain a substance of known melting point at a specific temp. e.g. Sulphur (115°C), Benzoic Acid (121°C) etc. Melting of the substances indicates a specific temp. Achieved in the heat process.

What are sterilization indicators?

Sterilization indicators, such as spore strips and indicator tape, enable routine monitoring, qualification,and load monitoring of the steam sterilization process. They indicate whether the conditions during a steam autoclave cycle were adequate to achieve a defined level of microbial inactivation.

What is autoclave tape called?

Autoclave tape (commonly called autoclave indicator tape) used in order to determine that items have gone through the sterilization process. Once it has passed through the steam sterilization process, the imprint will turn change colors.

Why do we sterilize surgical instruments?

Importance of Sterilizing Medical Equipment A surgical instrument or medical device that comes in contact with a patient’s mucous membranes or sterile tissue and carries a significant risk of introducing pathogenic microbes, potentially resulting in infection.

Why do we clean instruments before sterilization?

Thus, efficient cleaning of instruments is believed to be a key procedure for reducing the potential risks of onward transmission of vCJD. Effective cleaning is also vital to ensure microbial inactivation since retention of organic or inorganic debris may compromise subsequent disinfection or sterilization processes.

What are the different types of sterilization indicators?
