Surgical instruments, dressings, and certain other items are sterile and remain so until individual packages or seals are penetrated and contaminants are admitted. Microorganisms (including bacteria, spores, and viruses) can be completely destroyed through the process of sterilization. (3) Keeping from breathing, coughing, or sneezing on wounds or sterile items. (Dressings that are to be applied to wounds, needles, and instruments to be inserted through the skin, and syringes to be filled for injection into the body must not touch anything unsterile before being used.) (2) Ensuring that all sterile items are kept free from all organisms. (1) Keeping their hands clean and as free from contamination as possible. Treatment personnel can carry out aseptic technique by: (3) In surgery, it normally implies sterile conditions in and around the patient area.ī. (2) In administration of preparations by injection or infusion, it refers to measures designed to prevent or minimize introduction of pathogens beneath the skin. ![]() (1) With traumatic wounds, which are assumed to be contaminated beforehand, aseptic technique refers to applying a dressing in a manner so that additional contamination is not induced. This procedure is used to reduce the direct or indirect transfer of germs to any surface, article, or person. Aseptic technique is a discipline that consists of a series of events to guard the patient against infection. Reduce number of organisms and prevent spread of infection to others.Ī. Confine disease organisms and prevent spread to others. Potential host (other people and environment are reservoirs of infection). ![]() Outside of gown that is in contact with the sterile field must be kept sterile. Sterile gowns are worn to protect the patient from the worker. Inside of gown is clean outside of gown in contact with patient and his environment is contaminated. Clean gowns are worn to protect the worker. Hands and arms are dried with a sterile towel. Hands and forearms are scrubbed for 10 minutes to reduce the bacterial count on the skin surface. Hands and arms are dried with paper towels. Hands and forearms are washed for 1 to 2 minutes to remove surface contaminants and soil. Only sterile articles are brought into the sterile field. Once a sterile article touches an unsterile article, it is contaminated (unsterile). A zone about the site of operation or wound is established as a sterile field. Nothing goes out of the zone without being disinfected or wrapped in a clean cover to permit handling in a clean zone. Everything within the zone of isolation is contaminated. A zone about the isolation unit is established as contaminated. Patients requiring surgery are taken to the operating room of the hospital. Patients with a communicable disease are separated from the rest of the patients by room, ward, or unit. To prevent introduction of any organism into an open wound on the patient or into a body cavity. To reduce the transmission of pathogenic organisms from patient to another person. Sterility (freedom from all microorganisms). Cleanliness (freedom from most pathogenic organisms). ![]() All of the procedures used to sterilize and to keep sterile any objects or articles that are to be introduced into a wound or body cavity or that is to penetrate the skin. All of the procedures used to protect the patient and his environment from the spread of infectious organisms. Some of the differences between medical aseptic technique and surgical aseptic technique are listed below. Confusion sometimes results from erroneously thinking that medical asepsis and surgical asepsis are the same except one is used on a medical ward and the other is used in a surgical ward. Aseptic technique implies all those procedures that reduce or eliminate pathogens and their actions or minimize their areas of existence. These exercises will help you achieve the lesson objectives.Īsepsis is the condition of being free from disease-producing microorganisms.
