Which of the following is true of the AST guideline on bowel technique?

The assertion that instruments in the second Mayo stand are considered contaminated after coming in contact with the open GI tract aligns with the AST guidelines on bowel technique. When performing bowel surgeries, any instruments that come into direct contact with the contents of the gastrointestinal tract are at risk of contamination due to the presence of bacteria and other microorganisms. Thus, any instrument that has been exposed to the open GI tract must be deemed contaminated, reinforcing the need for strict adherence to sterile technique throughout the surgical procedure.

In addition, the guidelines emphasize the importance of maintaining sterility and preventing the spread of contaminants, which is crucial for ensuring patient safety and preventing postoperative infections. Understanding that those instruments that contact the bowel are no longer sterile helps surgical teams manage instruments appropriately and follow protocols for safety.

The other options present information that either deviates from the guidelines or lacks specificity. For example, not all instruments used in bowel procedures are designed for reusable use as some may be disposable. Additionally, while cleanliness is imperative for surgical instruments, the requirement for all instruments to be cleaned prior to bowel surgeries pertains more to the instruments’ prior usage rather than a specific AST regulation before the surgical procedure. Thus, option B accurately reflects the critical considerations outlined in the AST guidelines regarding bowel technique in surgery.
