Hot instruments
After sterilization in a pre-vac steam sterilizer, the instruments are cooled for at least a half hour. Is it ever acceptable to shorten this cooling time and open the instruments immediately (without ever storing them)?

If you are performing a standard sterilization cycle, drying time is included. Instruments/trays removed from an autoclave should never be wet, if they are, you need service. If instruments are immediately needed, which is usually the case in an ASC, they should be immersed in cool sterile H2O, not saline. Marie D.

As David notes, it is essentially "flashing" the instruments. If the instruments can be immersed, they can be placed in sterile water or iced sterile saline or water(from the MH cart) to accelerate cooling. Passive cooling is not a requirement. The presence of water droplets is irrelevant- they are made from condensed steam. If the sterilization cycle has been completed, the instruments are sterile even if wet. If the cycle has been abbreviated for any reason, the instruments would not be considered sterile. Carl Noback (Medical Director/Chief Surgeon) at February 28, 2012 (6:06 pm) |

I am rather surprised by some of the answers here. The correct answer is, "When they are no longer hot enough to burn the patient or the OR staff, but also when the humidity in the package has equilibrated with the surroundings to ensure that the packaging is not compromised as a sterile barrier by condensed moisture."

Time to go back to Alexander's Care of the Patient in Surgery. These answers were part of my training back in 1986. Steam droplets came from inside the jacket yes? The steam cycle test registered effective? yes? Maria Todd (Administrator/Director/Manager/Owner/Exec. Officer) at February 28, 2012 (4:13 pm) |

How are you shortening the cooling time? The instruments need to be cooled on there own time. The instruments need to be cooled prior to use, but do not need to be stored for a specific period of time. You need to be able to track instruments while the biologicals are being processed in case of failure of passing. You will need to follow up with the surgeon. Steven S.

Yes, you can use them immediately. It would be the same as flashing in a flash case. Instruments should be cool enough to handle. Water inside the case is sterile and would normally evaporate as they are dried. The only risk you run is if the water saturates the bottom of the cover and starts a wicking effect. David K.

I would also like to expand on this question to ask....IF it is acceptable to open the instruments immediately, are the instruments still considered sterile if water droplets are present? Lynn Feldman (Administrator/Director/Manager/Owner/Exec. Officer) at February 28, 2012 (3:09 pm) |
