Explain Asepsis, Antisepsis And Cross Infection.

1 Define and explain asepsis, antisepsis and cross infection

Asepsis- An environment that is free of harmful microorganisms. An aseptic technique ensures that only uncontaminated equipment and fluids come into contact with susceptible body sites. It should be used during any clinical procedure that bypasses the body's natural defences. Using the principles of asepsis minimises the spread of organisms from one person to another. Aseptic techniques are used to reduce contamination from microorganisms. It involves strict guidelines that help to prevent infection and minimize the risk of catching one. If an infection is caught and is left without treatment, it can spread throughout the body making an individual very poorly with the risk of sepsis.
The Greek root word, 'anti', means against, while 'sepsis' means putrefaction or decay, so antisepsis means against decay or infection, a critical part of any recovery process. These tiny infectious germs are called microorganisms, and they try to get into the body through cuts or wounds whenever the body's defense mechanisms are breached or compromised. The substance used in antisepsis is called an antiseptic, which is used to kill a broad range of infections. An antiseptic is different from an antibiotic, which is used to target a certain type of bacteria. Once scientists and surgeons learned more about bacteria and the connection between bacteria and infection, they developed ways to prevent the latter. Antiseptics are applied to the skin to reduce the possibility of infection. Common antiseptics include rubbing alcohol, boric acid, hydrogen peroxide and
The spread of infection can occur between people, pieces of equipment, or within the body. These infections can cause many complications. So, medical professionals work hard to ensure equipment safety and a clean environment. Harmful Microorganisms included bacteria, viruses, fungi and parasites. Washing your hands frequently and practicing good hygiene is the best way to prevent getting an infection.
Examples of how microorganisms can be transmitted include; Unsterilized medical equipment, coughing and sneezing, human contact, touching contaminated objects, dirty bedding.
The risk for infection is greater when undergoing a medical procedure. But cross infection can happen within the body. An infection in one part of the body can spread to another, like a respiratory infection spreading to the ears or eyes.
Aseptic technique is a common process used to sterilize equipment so harmful microorganisms can’t spread from patient to patient. Hospital and healthcare settings all have procedures to prevent infection.
