Fresh Frozen Plasma Storage
Correct fresh frozen plasma storage is vital for safe and efficient treatment of patients with blood clotting disorders in various situations.
This article will explore fresh frozen plasma preparation, storage and uses and discuss the Froilabo products that can aid your fresh frozen plasma storage.
Fresh Frozen Plasma Preparation
Plasma is the liquid portion of whole blood. It contains many important components such as water, minerals, clotting factors, proteins, electrolytes, and anticoagulants.
Fresh frozen plasma is prepared by separating whole blood and extracting the liquid portion (plasma). This can be carried out in two ways:
- Centrifugation – previously tested whole blood is placed in a centrifuge to separate the plasma from the rest of the blood.
- Plasmapheresis – blood is extracted from a donor, plasma is then removed and the rest of the blood is returned to the donor.
Fresh Frozen Plasma Uses
Fresh frozen plasma has several uses. It can be used to treat patients with a blood clotting condition who are bleeding or at risk of bleeding and unable to receive the isolated coagulation factor, or another plasma component concentrate they need before planned surgery. Other fresh frozen plasma uses include:
- Treating multiple factory deficiency (caused by liver disease)
- Treating antithrombin (III) deficiency
- Plasma exchange in patients with Thrombotic Thrombocytopenic Purpura (TTP)
- Emergency reversal of warfarin in patients with bleeding or if they need surgery (if vitamin K treatment is unavailable or would take too long)
Fresh frozen plasma should not be used for the replacement of blood volume.
Fresh Frozen Plasma Storage
Once the plasma has been collected it must be frozen within 8 hours. To ensure the quality and the efficacy of the plasma, it must be frozen rapidly to very low temperatures. For up to one year, the fresh frozen plasma storage temperature should be below -30 °C. If kept in an ultra-low temperature freezer with a storage temperature below -60 °C, the plasma can last for up to seven years.
When the fresh frozen plasma is ready to be used, thawing should take around 1 hour. The plasma must be refrigerated at a temperature of 4 °C and used within 24 hours.
