This means that if it is wet and not yours you should use the appropriate personal protective equipment (PPE) and perform hand hygiene after handling potentially contaminated fluids, and when performing patient care activities that require moving from dirty to clean patient care activities. When we fail to take the opportunity to perform hand hygiene between patients or clean and disinfect shared patient equipment between patients, we are creating opportunities for cross contamination that can introduce new, harmful microbes to patients.6principles of Medical AsepsisAll body fluids from any patient should be considered contaminatedBody fluids can be the source of infection for the patient and youUtilize appropriate personal protective equipment (PPE)The third principle of asepsis is recognizing that any body fluid is potentially contaminated. All of us are colonized with many different types of bacteria, some helpful and some potentially pathogenic. The second principle of asepsis is focused on preventing the transfer of microorganisms from one patient to another via healthcare provider hands and shared equipment. 5principles of Medical AsepsisEven though skin is an effective barrier against microbial invasion, a patient can become colonized with other microbes if precautions are not taken.Perform hand hygiene between patient contactsWhen handling items that only touch patients intact skin, or do not ordinarily touch the patient, make sure item is clean and disinfected (between patients). When we bypass the skin, we increase the susceptibility of the patient to invading microorganisms. When performing invasive procedures, like placing an IV or giving an injection, one of the bodies first lines of defense against invading microorganisms is bypassed: the skin. When approaching each patient care activity, consider the following principles as a framework to guide your practice.Ĥprinciples of Medical AsepsisWhen the body is penetrated, natural barriers such as skin and mucous membranes are bypassed, making the patient susceptible to microbes that might enter.Perform hand hygiene and put on glovesWhen invading sterile areas of the body, maintain the sterility of the body systemWhen placing an item into a sterile area of the body, make sure the item is sterile To achieve medical asepsis we must understand what is dirty, what is clean, what is sterile, how to keep these things separate, and how to remedy any contamination that might occur. 3Medical AsepsisMeasures aimed at controlling the number of microorganisms and/or preventing or reducing the transmission of microbes from one person-to-another: Clean TechniqueKnow what is dirtyKnow what is cleanKnow what is sterileKeep the first three conditions separateRemedy contamination immediatelyMedical asepsis is based on several measures with the goal of controlling the number of microorganisms, not making things sterile. Unlike medical asepsis, the goal of surgical asepsis is to ideally remove all pathogenic organisms and prevent the introduction of any organism into a normal sterile body site. With medical asepsis, emphasis is placed on removing most of the pathogenic organisms to reduce transmission from one patient to another.Conversely, surgical asepsis, also called sterile technique, is used only during surgical procedures. Medical asepsis, also referred to as clean technique, is used during most routine patient care activities and non-surgical procedures. There are two types of asepsis, Medical and Surgical. Aseptic technique refers to all those procedures that reduce or eliminate pathogens and their actions or minimize their areas of existence. Prevent introduction of any organism into an open wound or sterile body cavityAsepsis is the condition of being free from disease producing microorganisms.
