Study Notes
Aseptic Technique Overview
- A sterile field reduces contamination risk during surgical procedures.
- Proper understanding of sterile fields, gloves, and hand scrubbing is crucial for surgical safety.
Incorrect Elements of a Sterile Field
- Folding arms while wearing sterile gloves compromises their sterility.
- A sterile field encompasses all draped areas, including tables and gowns.
Contamination Definition
- An object containing even one microorganism is classified as contaminated.
- Sterilization removes all microorganisms; sanitation and disinfection lower microbial counts but don’t guarantee complete microbial free status.
Masks and Proper Usage
- Masks must ensure air filters through, preventing escape around edges.
- Moisture reduces mask filtration effectiveness.
- Masks should be properly secured with ties to maintain fit and effectiveness, ideally with one tie on top and another behind.
Draping Techniques
- Tables should be draped starting from the front to the back, using a cuffing technique to keep gloves sterile during the process.
Hand Scrubbing Purpose
- The scrub aims to render skin surgically clean, minimizing microbial presence, but does not achieve complete sterility.
Steam Sterilization and Item Handling
- Certain items, like suction tips and asepto syringes, may not maintain sterility post-steam sterilization.
- Proper handling and placement during sterilization are critical for maintaining sterility.
Gloving Techniques
- Closed gloving technique is preferred to reduce contamination risk.
- Open gloving may be necessary for changing a single glove during surgery.
Pressure Steam Sterilizer Loading Protocol
- Liquids should not be placed at the start to prevent spillage; they are last loaded.
- Correct loading involves placing linen packs upright, canisters on sides, and mesh-bottom trays flat.
Sterility Assumptions
- Assume items are not sterile if there is any doubt.
- The inner edges of wrappers are not sterile; sterility is maintained only in the center and on clean surfaces.
Prep Site Scrubbing Protocols
- Areas such as colostomies should be scrubbed last using disposable sponges to avoid contaminating already cleaned surfaces.
Operating Room Cleaning Standards
- Floors should be disinfected with a germicidal solution at the end of each case to ensure a sterile environment.
- Merely using detergents without germicidal agents is insufficient for effective cleaning in an operating room context.
