8 Hour Infection Control Flashcards

Guidelines used to prevent exposure to HBV and HIV and other diseases during procedures in health care settings by avoiding contact with patient body fluids.

It is in the best interest of everyone to assume that all patients are infectious and capable of transmitting disease.

PPE (personal protective equipment), hand-washing (scrubbing in), barrier techniques.

<ol> <li>Cleaning off soil. Then disinfection. You will use one of three methods: ultrasonic cleaner, thermal disinfector, or chemical. 2. Inspection. Before inspection, swap gloves. Inspect each instrument for function and cleanliness after cleaning. 3. Packaging. Place lightweight instruments into sterilization pouches. Remove excess air. If package doesn't already include a chemical indicator, this should be added to the pouch. 4. Sterilization. Sterilization will be completed in one of three ways: steam sterilization (autoclave), chemical vapor (chemiclave), or dry heat (dryclave). There is also cold sterilization (though unpopular), which is the use of liquid chemical germicides. This can take up to 10 hours of exposure. 5. Sterile storage. Once sterilized and inspected for assurance, packages should be stored in a sterile area.</li> </ol> Signup and view all the answers

<ol> <li>Empty operatory unit water bottle, fill with 4 - 6 oz of water (distilled water is highly recommended). 2. Drop microbial tablet into unit water bottle and swirl the bottle until the tablet is resolved. 3. Reattach unit water bottle to the chair. 4. To shock the waterlines, run each of the handpieces into a cup until the colored water is visible. This indicates the shock treatment is in the lines. 5. Allow shock treatment to stay in the lines overnight, or if possible, over the weekend. 6. The next day, empty the unit water bottle and fill it with water. 7. Drop a daily maintenance tablet into the bottle. 8. Again run each handpiece until the water runs clear. 9. Drop a daily maintenance tablet every time you refill your bottle.</li> </ol> Signup and view all the answers

<ol> <li>Remove handpieces, attachments, and motors from each unit. 2. Wipe waterline outlets (syringe tips, handpiece tubing terminals, etc.) with an alcohol wipe to avoid external contaminants. 3. Collect an equal amount of water from each sampled outlet (e.g., if there are two handpiece tubings and two A/W syringes, collect approximately one-fourth of the water sample from each outlet). 4. Follow the instructions provided with the monitoring kit for collecting the samples. 5. Follow the monitoring kit instructions for handling, storing, and processing the sample. If bacterial count is at or above 500CFU/ml, shock the waterlines. If bacterial count is below 500CFU/ml, proceed with waterline maintenance.</li> </ol> Signup and view all the answers

<ol> <li>Fill each water bottle with a 1:10 sodium hypochlorite solution (1 ounce of household bleach to 10 ounces of water). 2. Run each A/W syringe for about 15 seconds until you smell bleach. 3. Remove the high-speed handpiece from the end of the line, place the handpiece connection into the sink and step on the pedal for a few seconds, running the water until you can smell bleach at the handpiece connection. This bleach smell verifies that the 1:10 dilution of bleach is in the lines. 4. Repeat this procedure for each A/W syringe and each handpiece in each operatory, leaving the diluted bleach in the lines for 10 minutes BUT not more than 15 minutes. Prolonged exposure to bleach can cause damage to the equipment. 5. Place a sign on the dental unit 'System is being treated. DO NOT USE!' 6. Disconnect the water bottles and discard the remaining diluted solution in the water bottles into the sink. DO NOT FLUSH BLEACH INTO ANY VACUUM SYSTEM THAT CONTAINS AN AMALGAM SEPARATOR. 7. Refill the water bottles with distilled water, reconnect the water bottles, and flush the bleach from each line in each operatory by running for 1-3 minutes each or until bleach smell disappears. 8. Start waterline maintenance protocol.</li> </ol> Signup and view all the answers

<ol> <li>At the beginning of each workday, discharge water from each device connected to the waterline at each dental unit for 20-30 seconds. 2. After clearing the operatory and following standard disinfection protocols following patient dismissal, discharge water for 20-30 seconds from each waterline and/or device that enters the patient's mouth before seating the next patient.</li> </ol> Signup and view all the answers
