Question

Aseptic surgery was introduced by
A. Agostiono Bassi
B. Rudolph Virchow
C. Pasteur
D. Joseph Lister

Answer 1

Hint: Aseptic technique is that which practices the procedure to prevent contamination from any kind of pathogen. This technique was first of all discovered by the scientist who is known as the father of modern surgery.

Complete answer:
Agostiono bassi was the Italian entomologist.
-Rudolph Virchow proposed the cell theory (‘Omnis cellula e cellula’) which means one cell arises from a pre-existing cell.
-Pasteur is associated with pasteurization (it is the partial sterilization of any products to make it safe for consumption) and immunization (against rabies, smallpox, and anthrax).
-Joseph Lister is known as the ‘father of modern surgery’ was a British surgeon. He found that after surgery also many people were dying because of infection. He discovered the method of antiseptic surgery by using phenol (Carbolic acid) as a disinfectant. He used to sterilize the surgical types of equipment with phenol before dressing any wound.
So, the correct answer is (D).

Additional information:
In antiseptic surgery, the prerequisite is sterilization and disinfection.
Sterilization: Removal of micro-organism along with their spores is called sterilization.
Disinfectant: It includes the destruction of micro-organism but their spores may or may not be destroyed.
And the chemical used for the removal of micro-organism from the skin, and does not cause any harm to the human being is called antiseptic (of them are made up of alcohol).
There are various methods of sterilization: Physical method and chemical method.
1) Physical method: include sterilization through sunlight, drying, dry heat, radiation.
2) Chemical method: it includes sterilization through gaseous substances like ethylene oxide, formaldehyde gas, or through liquid like alcohol, phenol.

Note: It is the technique which is widely used across the world, and was named after Louis Pasteur. In this method heating of beverages is done at 57 degrees celsius to prevent it from abnormal fermentation. Pasteurization of milk is practiced in many countries where milk is heated to 63 degree celsius for about 30 minutes.
