Blood  Transfusion  Policy 1

 The Receipt, Storage and Transport of Blood Products

1.1.1.      1.            Introduction

Blood is donated by unpaid donors and is processed by the National Blood Service (NHSBT) into three main components, these being:-

1.Red cell Concentrates

2.Fresh Frozen Plasma (FFP)

3.Platelets

4. Cryoprecipitate

Stocks of red cell units and FFP are kept at Basildon Hospital Blood Transfusion Department; Platelets are ordered from the NHSBT by the BMS staff in the Blood Transfusion Department at Basildon, as required on a Named-patient basis. However, two are kept in stock for emergency use.

1.1.2.      2.            Storage of Blood and Blood Products

Red Cell Units

Red cell units have a shelf life of 35 days from the time of donation if stored at 2 - 6oC in a specialised Blood Fridge designed to maintain the correct temperature. Once removed from a Blood Fridge, blood must not be allowed to warm up or cool down excessively, Transfusion must be started before 30 minutes have elapsed, if unable to do so blood must be returned to the appropriate blood bank. Failure to store blood at the correct temperature (4oC +/- 2oC) can cause the blood to deteriorate (due to bacterial growth), which can have a catastrophic effect on any patient subsequently transfused with that blood unit

Fresh Frozen Plasma (FFP)

FFP has a shelf life of two years from the time of donation, but only if it is stored at minus 30 oC or below in a Freezer designed to maintain the correct temperature.

When FFP is thawed and issued by the Laboratory, it should be transfused within 24 hours if stored at  ;2 - 6oC, aside from the risk of bacterial contamination, this is important as the clotting factors in FFP deteriorate rapidly.

When transporting FFP between sites, it must be sent in a Blood box with a Cold Insert in the same manner as for Red cell units.

Platelets

Platelets units have a shelf life of 7 days from the time of donation, but only if it is stored at  22 +/- 2 oC and aggitated correctly (in a purpose built Platelet Incubator).

Under no circumstances must Platelet units be refrigerated or left unmixed for prolonged periods; once collected Platelets must be administered without delay.

When transporting Platelets between sites, they must be sent in a Blood box without a Cold Insert.

Cryoprecipitate

Cryoprecipitate has a shelf life of two years from the time of donation, but only if it is stored at
minus 30 oC or below in a Freezer designed to maintain the correct temperature.

When Cryoprecipitate has been thawed and issued by the Laboratory, it should be transfused within
4 hours when stored at  22 +/- 2 oC.

When transporting cryoprecipitate between sites, they must be sent in a Blood box without a Cold Insert.


Note:

Do not transport different blood product types in the same blood box
