Our facility uses the ArkBio microwave from Tropitronics out of Florida. It works great; However, there is some limitation, as it will not thaw units that may be trifolded. It is recommended by the manufacturer that units be frozen flat. Our supllier bends the top of the plasma units and they can be safely thawed. We cannot thaw pheresis units by microwave as they are trifolded and heat is not consistently applied for the whole unit. Additionaly, We adopted the practice of converting FFP to thawed plasma ater 6 hours with a 5 day outdate from time of original thaw. There are articles in the BB community supportive of Thawed Plasma for most patients, our exceptions are babies and patients in severe DIC who always get FFP. This has reduced FFP wastage to less than 1% (Usually a bag defect or rough transport handling-supplier gives us credit for these!)
