Between two emergency laparotomies, a hospital CSSD processes a dropped clamp using an immediate-use steam sterilization (IUSS, formerly flash sterilization) cycle. Which statement about IUSS is correct?
- A IUSS-processed instruments may be wrapped and stored in CSSD for later use
- B IUSS is acceptable only when there is an urgent need, the item must be transported aseptically and used promptly, and it must never replace terminal wrapped sterilization or be used for implants on a planned basis ✓
- C IUSS is the preferred routine method because it gives faster turnaround than wrapped cycles
- D IUSS cycles require no monitoring because the short exposure guarantees sterility
Correct answer: B. IUSS is acceptable only when there is an urgent need, the item must be transported aseptically and used promptly, and it must never replace terminal wrapped sterilization or be used for implants on a planned basis
Explanation
Immediate-use steam sterilization is restricted to instruments needed urgently, typically items dropped intraoperatively. Items cannot be wrapped, stored or transported off-site because the process provides no packaging barrier or drying, so sterility is maintained only until immediate use. Routine reliance on IUSS, its use for planned implants, and skipping biological and mechanical monitoring are all recognised deficiencies flagged in sterilization audits.
