Detailed explanation-1: -Joseph Lister is credited with reducing wound and surgical infections by introducing carbolic acid [7], used as a topical antiseptic. Lister’s theories of antisepsis evolved from the germ theory postulated by Pasteur [8].
Detailed explanation-2: -He looked for ways to prevent germs from entering a wound by creating a chemical barrier-which he called an antiseptic-between the surgical wound and the surroundings. The chemical he chose to use was carbolic acid, which killed the germs on contact.
Detailed explanation-3: -Antiseptic surgery was largely pioneered by Joseph Lister in the 1860s, when he used phenol (known at the time as carbolic acid) as a disinfectant. He would sterilize the operating theatre and surgical tools with phenol, and even soak bandages in the substance before dressing wounds.
Detailed explanation-4: -He found an effective antiseptic in carbolic acid, which had already been used as a means of cleansing foul-smelling sewers and had been empirically advised as a wound dressing in 1863. Lister first successfully used his new method on August 12, 1865; in March 1867 he published a series of cases.
Detailed explanation-5: -The development of the antiseptic system by Joseph Lister, Professor of Clinical Surgery at King’s between 1877 and 1893, strikingly changed this outlook for patients. Lister’s system reduced mortality rates from major operations from around 40 per cent to less than three per cent by 1910.
