The Dropped Scope: Immediate-Use Sterilization Versus a Priority Cycle
During a laparoscopic appendectomy at 2115 the scrub person drops the only 5-mm 30-degree laparoscope on the floor while passing it off the field. The surgeon says the case cannot be completed without it. Options raised in the room: (a) borrow the matching scope from OR 4, which finished at 1900 - that scope has been cleaned and is sealed in a tray waiting for the 2300 autoclave cycle; (b) run the dropped scope through immediate-use steam sterilization (IUSS) in the substerile gravity-displacement sterilizer; (c) close and bring the patient back. The patient is stable, the appendix is gangrenous, and the surgeon wants to finish within 30 minutes. Hospital policy permits IUSS only with an approved container, cycle monitoring, and a documented clinical justification.
1. Evaluate the three options and make a recommendation with your reasoning.

First, the dropped scope is contaminated and must go to decontamination before any reprocessing discussion - it cannot go into a sterilizer straight off the floor.
- Option (b), IUSS, is the weakest choice. IUSS is reserved for the situation where there is no alternative and the item is needed immediately. A 5-mm 30-degree scope is a lumened device; in a gravity-displacement sterilizer, steam penetration and air removal from a long narrow lumen are hard to assure, so the margin for error is poor and hard to validate. Films, char, and retained bioburden are real failure modes, and a failed IUSS on a body-cavity instrument is worse than a delay.
- Option (a) is the sound choice, with a modification. The OR 4 scope is already cleaned and sealed - the only constraint is the 2300 start time. The correct move is to ask sterile processing to advance that tray to the next available full cycle. That delivers a sterile, fully monitored, documented item rather than a flashed one, and probably in under an hour.
- Option (c) is disproportionate for a stable patient with a gangrenous but not perforated appendix.
I would also ask the surgeon whether a 0-degree scope (often available in multiple sets) would accomplish the remaining work, which may remove the delay entirely.
2. If the team nonetheless chooses IUSS, what must be true before that scope touches the field?

All of the following, and any missing one stops the process:
- The device's manufacturer instructions permit IUSS at the cycle parameters available on that sterilizer - if the IFU does not cover it, the answer is no.
- Full decontamination first: enzymatic cleaner, lumen brushed, flushed, rinsed, and dried.
- An approved container or tray intended for immediate-use cycles, with the item correctly loaded for steam access and the lumen positioned to drain.
- Cycle monitoring: physical parameters recorded (time, temperature, pressure), a chemical indicator inside and outside the package, and a biological indicator run in the same cycle.
- Aseptic delivery directly to the sterile field by a gloved nurse, with no storage - the item must be used immediately and cannot be put back for later.
- Documented clinical justification in the record, since policy requires it.
I would also state the residual risk out loud to the surgeon before the cycle starts, so the decision is a shared one rather than the nurse's alone.
3. What goes in the record, and what should be reviewed afterward?
Read the worked answer
Record: the time and nature of the contamination event; that the item was removed from the field; which alternative was used and when it arrived; if IUSS was used, the justification, the cycle parameters, indicator and biological indicator results, and who released the item; and notification of the surgeon and charge nurse.
Afterward, treat it as a system problem: why was there only one 30-degree scope available for a scheduled laparoscopic case (par level and tray configuration)? Why does a cleaned tray sit from 1900 to 2300 (sterilizer scheduling and staffing)? Is there a validated IUSS protocol for lumened scopes at all, and does the staff know it is discouraged for these devices?
The exam-style judgment here is the distinction between urgent and immediate use: the surgeon's 30 minutes creates urgency, not the absence of an alternative that IUSS requires.
