[Histonet] freezing spray

[Jennifer MacDonald]

Reasons against the use of freezing spray for frozen sections:
From the Federal Registry 1910.1030:  “All procedures involving blood or 
other potential infectious materials shall be performed in such a manner 
as to minimize splashing, spraying, spattering, or generation of droplets 
of these substances.”
From NCCLS (now CLSI) Document M29-T:  “Frozen sections done on unfixed 
tissue pose a high risk because accidents are common.  Freezing of tissue 
does not inactivate infectious agents.  Freezing propellants under 
pressure should not be used for frozen sections as they may cause 
spattering of droplets of infectious material.”

Our hospital has not allowed freezing spray to be used in the frozen 
section lab for many years.  We now have a new group of doctors who want 
to use the spray.  The docs think the frozen sections take too long to 
freeze.  Yet, they meet the frozen section TAT for more than 98% of our 
cases.  I think it's worth not using it for the one case where no one 
suspects TB but the patient will be positive.

Do you allow freezing spray in your frozen section lab?
