What is the platelezes of plates?

Inserts are part of the blood necessary in coagulation. When the tissue suffered injuries, the plates gather in place, create a barrier and activate other coagulation factors. Aferesis of plates is a method of collecting plates in which the blood is taken from the donor and is processed to remove the plates. The remaining experts will then return the remaining blood components to the donor. Blood then travels on a donor's arm tube and a specialized afferent machine that acts as an automated cell separator. Inside the machine, the blood is combined with an anticoagulant such as sodium citrate to prevent clotting.

Blood spins inside a sterile centrifugation with one use that separates the plates from the rest of the blood. Separate platelets are diverted into a designated bag and blood and some salt solution is returned to the patient's over -arm arms. If only one cannula is used, then the blood will return through this arm. In general, three to four cycles are carried out for the gift. This process usually takes 90 to 120 minutes.

Although the plates can be separated and used from the gifts of the whole blood, the afferent plates are much more effective in obtaining sufficient quantities. Each gift using pad afferenties can result in up to three usable units, while six units of blood are required to create one dose. The use of a single dose donor also minimizes the occurrence of transfusions or reactions that can be more common in associated products from a number of donors.

Due to the removal of a smaller amount of blood and because the body replaces the amount taken within 48 hours, the person can donate plates more often than blood. This is very useful due to the high demand for tables due to their relatively short durability of five days. They are used to treat a number of conditions where excessive bleeding can become a problem, for example in burn victims, bone marrow transplantation or organs and heart surgery.

Do you want to donThe hundreds must be more than 18 donors and in good health. Although the plates are tested into viruses such as HIV before they are converted to the patient, donors must also undergo health screening before allowing them to donate. Plates can be donated in specific hospitals, clinics and donor centers.
