A Loaner Implant Tray That Was Flash Sterilized Without a Final Biological Indicator
A 58-year-old woman is scheduled at 08:00 for primary total knee arthroplasty. The implant tray is a loaner that arrived at 06:45. Because the tray missed the overnight steam cycle, the sterile processing technician ran it through the immediate-use steam sterilizer, also called a flash cycle, at 07:10. The technician says the external chemical indicator has changed color. The biological indicator from the previous steam load is still incubating and will not be final for 18 hours. When you inspect the tray, the wrapper has a small water stain and the tray is still warm. The circulating nurse says, 'The indicator changed, so let us open it so we do not delay the surgeon.' The patient is already in the holding area with IV access, and the surgeon is scrubbing.
1. May you open and use this tray? Justify your answer using sterilization principles.

No. An external chemical indicator shows only that the package was exposed to the sterilization process. It does not prove sterility. Immediate-use steam sterilization is intended for urgent items, not routine implants. Implant loads require a biological indicator, and the implant must be quarantined until the biological indicator is read and negative. A water stain on the wrapper suggests strike-through or condensation, which compromises the sterile barrier. Warmth and residual moisture also raise concern for inadequate drying. The previous load's biological indicator is irrelevant to this tray and is still incubating. The correct decision is to reject the tray, keep it quarantined, and tell the circulator and surgeon that the implant cannot be used. The 08:00 start may need to be delayed or the case rescheduled. Sterility is a chain of evidence, not a color change.
2. What are your immediate actions, and who must be notified?
Read the worked answer
Quarantine the tray and do not open it. Notify the surgeon, charge nurse, sterile processing manager, and infection prevention immediately. Ask sterile processing to pull the load records for the immediate-use cycle, including cycle parameters, chemical indicator, and any biological indicator. Verify whether a biological indicator was run with this specific load. If not, the tray cannot be released. Check the loaner company's instructions for use and the facility policy for implant release. If another properly sterilized tray is available, use it and document the substitution. If not, delay the case and inform the patient and family. Complete an incident or deviation report and preserve the wrapper and tray for review. The goal is to prevent a preventable prosthetic joint infection, not to protect the schedule.
3. The surgeon demands the tray and says the delay is unacceptable. How do you escalate and document?
Read the worked answer
I would escalate in a graded way: first to the charge nurse and OR director, then to infection prevention and risk management, and if necessary to the chief of surgery. I would state the specific policy: implants require a negative biological indicator or documented release per policy, and a stained wrapper is a barrier breach. I would offer alternatives: wait for a new tray, use a different implant system, or reschedule. I would document the surgeon's demand, the policy cited, the people notified, and the final decision in the OR record and an incident report. If the surgeon proceeds anyway, I would not open or handle the tray and would ask that the refusal be documented. Professional obligation to the patient and facility policy outweigh hierarchy.
