1 STANDARD PRECAUTIONS ISOLATION PRACTICES STERILE TECHNIQUE

2 STANDARD PRECAUTIONS 1996, CDC developed a system of isolation to provide guidelines on how to prevent spread of infection (updated 2007) ………. practices are referred to as Standard Precautions (a 2 Tiered system).

3 Standard Precautions include Standard Precautions include wearing protective barriers wearing protective barriers when risk of contact with any body excretions, secretions, when risk of contact with any body excretions, secretions, and moist membranes and moist membranes and tissues. and tissues. Acknowledges that all are potentially Acknowledges that all are potentiallyinfectious.

4 FIRST TIER Precautions designed for care of all clients regardless of their diagnosis or presumed infection status. Standard Precautions apply to: 1) Blood 2) All body fluids, secretions, and excretions 3) Non-intact skin 4) Mucous Membranes

5 SECOND TIER It alerts the nurse to take additional precautions to interrupt the transmission of a specified infection or organism. These Transmission-Based Precautions are for patients known, or suspected of being infected by a particular pathogen transmission: (a) airborne precautions (a) airborne precautions (b) droplet precautions (b) droplet precautions (c) contact precautions (c) contact precautions

6 3 TRANSMISSION-BASED PRECAUTIONS (must understand how the organism is transmitted) Airborne Precautions: spread of microbes on small droplet nuclei through the air (< 5 microns). Airborne Precautions: spread of microbes on small droplet nuclei through the air (< 5 microns). (ie) Measles; Chicken Pox; TB *MASK important, door closed, negative air flow ventilation, private room Droplet Precautions: large particle droplets Droplet Precautions: large particle droplets (> 5 microns); which transmit 3 feet in air. (> 5 microns); which transmit 3 feet in air. (ie) Mumps; Pertussis; Influenza; SARS *Private room / or cohort clients, and mask worn if within 3 feet Contact Precautions: for prevention of disease transmitted by either direct / or indirect, contact. (ie) Impetigo, Scabies, Herpes Zoster, C Difficile. (ie) Impetigo, Scabies, Herpes Zoster, C Difficile. *Gloves and gown worn, private room or cohort clients *Gloves and gown worn, private room or cohort clients

7 BUGS ARE GETTING SMARTER THAN THE DRUGS!! Some microorganisms that are particularly difficult to destroy. Some microorganisms that are particularly difficult to destroy. Some prevalent ones are: Some prevalent ones are: ~ Methicillin-Resistant Staphylococcus Aureus (MRSA) ~ Vancomycin-Resistant Enterococcus (VRE)

9 ISOLATION IS……. Infection control and prevention methods that are used to decrease the transfer of microorganisms. Infection control and prevention methods that are used to decrease the transfer of microorganisms. Barriers or PPE (protective personal equipment) may include: gowns gowns gloves gloves masks masks eyewear/ goggles. eyewear/ goggles.

10 PROTECTIVE ISOLATION aka REVERSE ISOLATION Protects the client with a compromised or suppressed immune system; who is highly susceptible to contracting an infection.

11 Private room needed, door closed, gowns, masks, gloves (if direct contact), wash hands immediately before entering / leaving the room, no plants or flowers allowed.

12 PROCEDURE OF ISOLATION Prepare room for client; be organized! Prepare room for client; be organized! Before entering room, wash hands & put on the necessary barrier protection. Before entering room, wash hands & put on the necessary barrier protection. Place soiled linen & gown into an impermeable laundry bag. If splatter a possibility, nurses gown should also be impermeable. Place soiled linen & gown into an impermeable laundry bag. If splatter a possibility, nurses gown should also be impermeable. Wash hands & change gloves PRN during care. Wash hands & change gloves PRN during care. When care complete, PPE is removed inside room. When care complete, PPE is removed inside room.

13 In what order do you dress/undress PPE ? Must think critically, esp upon leaving isolation…..may depend upon the area in which you are working. As a general rule: ~ gloves are last put on & 1 st taken off ~ if airborne precautions, mask stays on until out of room. Consider your gloves, outside of your goggles, front of your mask, sleeves & front of your gown all to be contaminated. Remember to wash hands once all PPE removed. once all PPE removed.

14 LEAVING ISOLATION ROOM Remove your protective barriers in the following order: 1) Remove gloves 2) Remove eyewear/goggles 3) Remove gown (pull off inside out) 4) Remove mask 5) Wash hands immediately Leave mask on until after you leave room if airborne

15 CLIENT CONCERNS RELATED TO ISOLATION Explain purpose of isolation & the necessary precautions. Sensory deprivation may be evident by signs of loneliness or boredom. by signs of loneliness or boredom. S & S of depression - decreased motivation, anger, lack of appetite, or difficulty sleeping. What interventions can you plan, while working with a client in isolation?

16 STERILE TECHNIQUE aka SURGICAL ASEPSIS

17 What is the purpose of STERILE TECHNIQUE ?

18 PURPOSE OF STERILE TECHNIQUE PURPOSE OF STERILE TECHNIQUE To ELIMINATE all microorganisms from objects that come into contact with the tissues of the body that are normally sterile.

19 Where do we use Sterile Equipment and Implement Sterile Technique? Where do we use Sterile Equipment and Implement Sterile Technique? Operating room Operating room Labor and delivery Labor and delivery Major diagnostic / special procedure areas Major diagnostic / special procedure areas At the bedside in 3 main situations: At the bedside in 3 main situations: 1) Procedures requiring intentional perforation of the skin ie. Inserting an IV or an injection 2) If the skins integrity is broken due to surgery or burns ie. Dressing changes / cleansing wounds 3) During procedures involving insertion of devices, into normally sterile body cavities ie. Urinary catheter

20 HOW DO THINGS BECOME STERILIZED ? Autoclave - moist heat under pressure for surgical instruments Autoclave - moist heat under pressure for surgical instruments Radiation - for drugs & other heat sensitive items Radiation - for drugs & other heat sensitive items Chemicals - disinfect instruments (chlorine bleach) Chemicals - disinfect instruments (chlorine bleach) Ethylene Oxide Gas - for rubber and plastic Ethylene Oxide Gas - for rubber and plastic What about boiling water? What about boiling water?

21 How do we know if an item is Sterilized? If commercially prepackaged (disposable): …….. check the integrity of the package …….. check the integrity of the package If reusable equipment (sterilized within the facility): …… check integrity / expiration date / & also look for specially marked tape on the package …… check integrity / expiration date / & also look for specially marked tape on the package

22 AREAS WHERE STERILE EQUIPMENT IS USED AND STERILE TECHNIQUE IS NECESSARY Operating room Operating room Labor and Delivery Labor and Delivery Major diagnostic areas Major diagnostic areas At the bedside in 3 main situations At the bedside in 3 main situations –intentional perforation of skin (IV/injection) –when skin integrity is broken (dsg change) –inserting device into sterile body cavity (catheter)

23 Principles of Surgical Asepsis p Fundamentals text A sterile object remains sterile only when touched by another sterile object. A sterile object remains sterile only when touched by another sterile object. Only sterile objects may be placed on a sterile field. Only sterile objects may be placed on a sterile field. A sterile object/ or field out of the range of vision, or an object held below waist level, is considered contaminated. A sterile object/ or field out of the range of vision, or an object held below waist level, is considered contaminated. A sterile object/or field, becomes contaminated by prolonged exposure to air. A sterile object/or field, becomes contaminated by prolonged exposure to air.

24 …..Surgical Aseptic Principles continued…. If in contact with a wet contaminated surface, the sterile object/ or field becomes contaminated by capillary action. If in contact with a wet contaminated surface, the sterile object/ or field becomes contaminated by capillary action. Microbes move in the direction of gravity. Microbes move in the direction of gravity. Edges of a sterile field are considered contaminated….a 2.5cm border. Edges of a sterile field are considered contaminated….a 2.5cm border. If ever in doubt - consider it unsterile! If ever in doubt - consider it unsterile!

25 Preparing a a Sterile Dressing Tray

26 Prepare the sterile field….. Prepare the sterile field….. Sterile Pack …… Sterile Pack …… Add item to the sterile field…… Add liquid to the sterile field……. When all of the above is complete……glove

27 STERILE GLOVES STERILE GLOVES Dominant hand is gloved first. Do not touch outside of 1 st glove, only the inside cuff (which is folded over) Dominant hand is gloved first. Do not touch outside of 1 st glove, only the inside cuff (which is folded over) Then with sterile gloved dominant hand, pick up 2 nd glove by reaching under cuff. Then with sterile gloved dominant hand, pick up 2 nd glove by reaching under cuff. Keep thumb fully abducted & ensure hands remain above the waistline. Keep thumb fully abducted & ensure hands remain above the waistline.
