Study Notes
Sterile Field and Contamination
- A sterile field minimizes contamination risk; incorrect items disrupt sterility.
- Gloves that are folded and not in use are not considered part of a sterile field.
- An item is deemed contaminated if it has even one living microorganism; sterilization eliminates all microbes.
Masks and Their Usage
- Masks must fit correctly to ensure proper filtration and minimize escape of air around the mask.
- Moisture reduces mask effectiveness; ties should be secured one on top and one behind the neck for optimal fit.
Draping Techniques
- The scrub nurse drapes tables from front to back while cuffing the drape edge to protect gloves from contamination.
- Surgical hand scrub aims to render skin surgically clean, reducing microbial load but not guaranteeing sterility.
Steam Sterilization Practices
- Items like suction tips and asepto syringes may not remain sterile without proper handling after sterilization.
- Closed gloving is preferred for minimizing contamination; open gloving is utilized for changing single gloves during procedures.
Pressure Steam Sterilizer Loading
- Liquids should be loaded last in a steam sterilizer to prevent spillage and contamination of other items.
- Proper loading practices include placing linen packs upright and keeping canisters on their sides.
Sterility Guidelines
- Any doubt about sterility should lead to treating the object as non-sterile.
- Edges of wrappers are not considered sterile; sterile personnel must avoid unsterile areas and should turn away when passing them.
Surgical Prep Site Considerations
- If a prep site has a colostomy or draining sinus, it should be scrubbed last with single-use sponges to avoid contamination.
Operating Room Cleaning
- Operating room floors must be cleaned with a germicidal solution to eliminate microorganisms effectively.
- High standards for cleanliness in operating rooms require thorough disinfecting practices, ensuring the absence of potential contaminants.
