Short Answer 
To ensure a sterile environment during medical procedures, create and maintain a sterile field using sterile drapes, gowns, and gloves, while regularly checking for contamination. Use only sterilized items that do not come into contact with non-sterile surfaces, and handle them carefully by keeping them above waist level and seeking assistance when necessary to maintain sterility.
1. Create and Maintain a Sterile Field
A sterile field is crucial as it ensures an area that is free from microorganisms. To establish this, use sterile drapes, gowns, and gloves, and make sure that all equipment and surfaces within the area are also sterile. Regularly check the field for any potential contamination to keep it safe for use.
2. Use Only Sterile Items
It is vital that only sterilized items come into contact with the sterile field. This includes all instruments, dressings, and solutions. Not adhering to this principle could compromise the sterility of the field and increase the risk of infection.
3. Handle Sterile Items with Care
When dealing with sterile items, care must be taken to prevent contamination. Always hold these items above waist level and avoid contact with non-sterile surfaces. Additionally, rather than reaching over the sterile field, request assistance from a non-sterile team member for passing items, ensuring sterility is maintained throughout the procedure.
