Essay On Platelet Collection Method

Platelet collection methods Introduction;

Platelet transfusion are given to patient with severe thrombocytopenia associated with failure of platelet production . the commonest indications arise in the treatment of acute leukemia and other neoplastic conditions involving the bone marrow and in depression of heamopoiesis by infections, drugs or unknown causes . platelet can be collected by two methods either by whole blood donation or by apheresis.

Methods and materials ;

Preparation of PRP : PRP is obtained from patient's blood drawn at the time of temperature . A 30 cc venous blood draw will yield 3-5 cc of PRP depending on the baseline platelet count of an individual , the device used, and the technique employed . the blood draw occurs with the addition of an anticoagulant , such as citrate dextrose A to prevent platelet activation prior to its use. PRP is

Cytomegalovirus (CMV) status , and blood type for certain recipients . (2)

Disadvantages of plateletpheresis are it is a more expensive technique and it is not without risk to the donor (3).it is also time consuming whole blood donations take 15 min and the whole appointment one hour while the platelet donation takes about 45 min and the whole appointment takes one and half hour . (5)

Discussion ;

The apheresis platelet preparation is better than platelet from a whole blood because of the platelets derived from a single whole blood unit are not numerous enough for a dose to give to an adult patient so they must be pooled from multiple donors to create a single transfusion this result in exposure of the recipient to multiple donors in a single transfusion

While plateletpheresis provides the equivalent of six or more units of platelet so, this lead to exposure of the recipient to a single donor rather than multiple donors
