Antiseptics and Disinfectants

Antiseptics and disinfectants are classified as drugs.
Antiseptics are applied to living tissue while disinfectants are applied to inanimate objects.
Disinfectants are too harsh for living tissue and most often applied to medical instruments and the environment of care.
Antiseptics and disinfectants can be bacteriostatic or bactericidal.
Bacteriostatic agents retard growth and replication of bacteria, while bactericidal agents kill microorganisms.
Denaturing, a key pharmacological action of antiseptics and disinfectants, involves altering the organism's cell wall protein, causing it to coagulate and the cell to die.
Antiseptics also lower the surface tension of the cell wall, increasing fluid shift into the cell, leading to rupture and death.
Disinfectants act by biochemical interference directly with the metabolic process of the microorganism, reducing organism multiplication.
Topical agents used to treat established local infection have been largely replaced by systemic anti-infective drugs due to their higher effectiveness and lower risk of tissue damage.
Hand hygiene is the most important factor in preventing infection spread in healthcare settings.
The CDC recommends alcohol-based hand rubs for routine hand antisepsis due to their accessibility, time savings, and less skin damage in comparison to soap and water.
Alcohol-based hand rubs are not effective against C.difficile spores.
Soap and water hand washing is the preferred method of hand decontamination after contact with patients infected with C.difficile.
Nurses play a vital role in reducing the risk of hospital-acquired infections. They are responsible for washing their hands and reminding other healthcare professionals to do the same.
Disinfectant cleaning of the environment using chlorine bleach wipes or a 1:10 chlorine bleach solution is also an important measure to prevent infection.
