Classical sterilization techniques using saturated steam under pressure or hot air are the most reliable and should be used whenever possible. Other sterilization methods include filtration, ionizing radiation (gamma and electron-beam radiation), and gas (ethylene oxide, formaldehyde).
Q. What did Dr Joseph Lister do?
Joseph Lister, Baron Lister of Lyme Regis OM, PC, PRS, FRCSE, FFPS (5 April 1827 – 10 February 1912), was a British surgeon, experimental pathologist and a pioneer of antiseptic surgery. Lister successfully introduced carbolic acid (now known as phenol) to sterilise surgical instruments and to clean wounds.

Q. Can humans be sterilized?
Sterilization procedures are intended to be permanent; reversal is generally difficult or impossible. There are multiple ways of having sterilization done, but the two that are used most frequently are tubal ligation for women and vasectomy for men. There are many different ways tubal sterilization can be accomplished.
Q. What is the fastest method of sterilization?
Filtration is the quickest way to sterilize solutions without heating. This method involves filtering with a pore size that is too small for microbes to pass through. Generally filters with a pore diameter of 0.2 um are used for the removal of bacteria.
Q. What are the disadvantages of flash sterilization?
Disadvantage of “flash” sterilization. Can only use unwrapped instruments & unwrapped instruments are no longer sterile once removed. Describe 3 forms of sterilization monitoring. 1) Physical- tempt, pressure, exposure time 2)chemical- change colors when exposed to certain conditions.
Q. What is autoclave principle?
An autoclave is a device that works on the principle of moist heat sterilisation, wherein saturated steam is generated under pressure in order to kill microorganisms such as bacteria, viruses, and even heat-resistant endospores from various types of instruments.
Q. What autoclave Cannot kill?
Autoclaves are capable of killing all types of microorganisms such as bacteria, viruses, and even spores, which are known to survive at high temperatures and can only be killed at temperatures around 130°C.
Q. Why is it called an autoclave?
The name “Autoclave” comes from Greek “auto” ultimately meaning self, and Latin “clavis” meaning key, thus a self-locking device. The first autoclave was essentially a pressure cooker and was originally invented as a method for preparing food by French physician Denis Papin around 1681.
