Objectives Identify the practices of aseptic technique and related terminology.
Terms Contaminated – living organism(s) present on an animate or inanimate surface – floors are always considered contaminated – Septic is another term for contaminated NOT
Terms Clean – removal of foreign matter such as organic material – example fecal matter, blood, body fluids Sterile – free of all living microorganisms
Terms Autoclave – process of sterilization that uses heat and steam under pressure to destroy all pathogens including spores and viruses Disinfect – removal of most pathogens through cleansing solutions
Autoclaves Types of processes used: – Ethylene Oxide – Chemical Vapor – Steam
Medical Asepsis (Clean Technique) refers to practices or procedures used to ensure a clean environment by removing or destroying diseases causing microorganisms after each patient procedure Importance – healthcare worker has DUTY AND OBLIGATION to patient to do this – must be ongoing battle
Surgical Asepsis (Sterile Technique) refers to all practices and precautions that ensure the environment is free of all microorganisms – aimed at destroying or stopping transmission of ALL microorganisms – special techniques for opening sterile packages, and working from a sterile field must be learned and practiced with precision
Principles of Aseptic Technique Keep sterile field within view Hold sterile objects above the waist Avoid spilling solutions on any cloth or disposable sterile drapes. Keep hands below shoulder level.
Use Sterile Technique whenever entering area of body that is not a natural route of entry when caring for wounds or burns, performing catheterizations, suctioning, tooth extractions, surgery, etc. failure to follow these guidelines could cause illness or death to patient
Patient Care Guidelines wash hands before and after patient care, and handling supplies handle dressing, bandages and tissues according to policy wrap damp or wet items in waterproof bags discard disposable items use equipment and supplies for one patient only cover breaks in skin with a sterile dressing prevent cross contamination
Patient Care Guidelines keep food and beverages clean floors are contaminated avoid raising dust – airborne – do not shake linens clean from least soiled to most soiled discard liquids directly into drain or toilet avoid spilling and splashing keep rooms bright, clean, dry, and airy if in question, ITS CONTAMINATED
Open Skin Lesions – healthcare workers with draining lesions or weeping dermatitis, should refrain from direct patient care or food handling – report condition to supervisor for direction as this may vary per facility or department
Healthcare Workers Should Be: – *clean and neat – *wash uniform daily – *shower daily, including hair – *have short hair or secure it back – *brush teeth regularly – *proper nail care (follow policy of facility) fake nails may grow fungus under nail deadly to patients – *wear no jewelry
Handle Equipment Properly failure to follow the guidelines for correct technique in handling of equipment could result in serious infections to patient or healthcare worker
Proper Cleaning Solutions: – bacteriostatic slows down or stops growth of bacteria – bacteriocidal kills bacteria – household bleach solution 1:10 ratio kills all pathogens on objects and surfaces cleansed with solution must be made fresh daily – iodine and alcohol frequently used on skin for disinfecting
Handwashing – *prevents spreading infection – *wash before gloving and after removal of gloves – *wash before & after every patient contact & after exposure to blood or body fluids – *single most important procedure to prevent the spread of disease!
Handwashing – *use 3 - 5 ml. of soap – *vigorous friction rubbing not to exceed 15 seconds – *rinse with fingers pointed down – *dry fingertips to wrist – *shut off faucet with clean towel
Sanitation of Equipment – clean contaminated, reusable equipment by cleansing with soap/water & brush. Rinse & dry thoroughly before packaging & sterilizing – sterilize reusable equipment that will invade the body or mucous membrane – disinfect reusable equipment used for non- invasive procedures
Knowledge Assessment Compare and contrast the terms contaminated, clean, and sterile. List the types of autoclaved processes used. List the principles of aseptic technique. Understand the principles of patient care guidelines involving asepsis. Contrast the different cleaning solutions. Identify key components in hand washing considerations and technique.
