![]() Sterile technique requires a combination of meticulous hand washing, creation of a sterile field, using long-lasting antimicrobial cleansing agents such as betadine, donning sterile gloves, and using sterile devices and instruments. It is the standard of care for surgical procedures, invasive wound management, and central line care. ![]() Sterile technique (also called surgical asepsis) seeks to eliminate every potential microorganism in and around a sterile field while also maintaining objects as free from microorganisms as possible. In the most simplistic terms, asepsis is creating a protective barrier from pathogens, whereas sterile technique is a purposeful attack on microorganisms. Both asepsis and sterility are closely related, and the shared concept between the two terms is removal of harmful microorganisms that can cause infection. There is often misunderstanding between the terms aseptic technique and sterile technique in the health care setting. These potentially infectious, microscopic organisms can be present in the environment, on an instrument, in liquids, on skin surfaces, or within a wound. In the clinical setting, aseptic technique refers to the purposeful prevention of microbe contamination from one person or object to another. The word “aseptic” literally means an absence of disease-causing microbes and pathogens. When performed properly, aseptic technique prevents contamination and transfer of pathogens to the patient from caregiver hands, surfaces, and equipment during routine care or procedures. For example, a nurse administering parenteral medication or performing urinary catheterization uses aseptic technique. ![]() Cost to the health-care system = $4.In addition to using standard precautions and transmission-based precautions, aseptic technique (also called medical asepsis) is the purposeful reduction of pathogens to prevent the transfer of microorganisms from one person or object to another during a medical procedure.Nosocomial Infection An infection acquired in a health-care facility WBC enter the tissues causing release of pyrogens (fever) exudates form discharge healing occurs.Cells, proteins, fluids enter the tissue spaces blocking lymphatics to create a ‘wall’ against infection Tissue dies causing release of chemicals (histamine and prostaglandins) which allow blood vessel permeability.Aterioles dilate, blood and WBC go to area.Ex: fever, anorexia, n/v, lymph node swelling.Affects the entire body and may involve multiple organs, goes through the stages of infection.Ex: redness, warmth, tenderness, swelling.Limited to a defined area resembles inflammation.e.g., Hypertension, diabetes mellitus, osteomyelitis Latent - Infection present with no discernible symptoms.e.g., Common cold Chronic - Slow development, long duration.Affects many regions (e.g., septicemia)Ĭlassification of Infections by Duration Acute - Rapid onset of short duration.Occurs in a limited region in the body (e.g., urinary tract infection).Convalescence: Tissue repair, return to healthĬlassification of Infections By Location:.Prodromal: Appearance of vague symptoms not all diseases have this stage.Incubation: From time of infection until manifestation of symptoms can infect others.Wounds, surgical sites, IV or drainage tube sites.Eye, nares, mouth, vagina, cuts, scrapes.Airborne: Via air conditioning, sweeping Portal of Exit:.Direct – touching, kissing, sexual contact.The Spread of Infection Mode of Transmission: Food, floors, equipment, contaminated water. ![]() Normal flora that become pathogenic Reservoir.The Spread of Infection: Six Links Infectious agents Pesticides, food additives, medications, industrial.Parasitic worms found in soil transmitted via hand to mouth.Organisms multiply in animal hosts and transmit to humans through bites.Single celled organism spread by feces,.Organisms that exist by feeding on organic matter.Smallest of all pathogens replication within the host.One celled, multiply rapidly, classified by shape and how they cluster together. ![]()
