What is the Apheresis?

The techniques of aferesi and of picked multicomponenti is placed side by side to the traditional splitting up for the harvest of the single components of the blood.
The plasmaferesi is the donation of the solo plasma through procedure of separation (for centrifugazione or filtering) that it happens during the same session of collecting with immediate restitution of the part corpuscolata (globules and plaques) to the donor. Up to 650 mls of plasma can be withdrawn for single donation and with least time slice allowed among two donations of plasma and between a donation of plasma and one of whole blood or citoaferesi of fourteen days; among a donation of whole blood or citoaferesi and one of plasma the interval is of one month. The requisite of fitness of the donors of plasma are equal to those of the donation of whole blood, even if the plasmaferesi in reality represents more globally a practice born and more easily practicable from all those people that, as the women in fertile age, have for example values of hemoglobin and number of red globules to the inferior limits to the norm, really because these components are returned to the donor during the same session, that hard around mezz'ora.
 

The picked plasma is immediately frozen and you/he/she can be preserved up to 12 months. From it you/they will be extracted, through industrial splitting up: albumin, immunoglobuline and factors of the coagulation.
The typology of more frequent citoaferesi is the piastrinoaferesi that allows the collecting of the only plaques.
Besides the necessary requisite to the donation of whole blood, the donor of plaques will have to have a normal order emocoagulativo. You/he/she is effected with methodic of centrifugazione, through some cycles during which the used equipment, separates the part corpuscolata of the blood from the plasma. From the part corpuscolata is automatically extracted to closed circuit, without possibility of contamination, the plaques that are picked up in a special knapsack. The cycle concludes him with the reinfusione to the donor of the plasma of the red globules and the white globules. To this point it begins the new cycle up to the attainment of the quota desired of plaques. You/they cannot be performed, as a rule, more than 6 piastrinoaferesis a year; the least interval allowed among two piastrinoaferesis and between a piastrinoaferesi and a donation of whole blood is of fourteen days, while between a donation of whole blood and a piastrinoaferesi it is of one month. The whole procedure lasts around a hour. The picked plaques will be used within 5 days by the collecting for the therapy of some serious illnesses as for example the leukemias, for the patient oncologicis in chemotherapy and as I support fundamental in the bone marrow transplants bony.

 

The donation in aferesi is not very diffused in the ns. zone, and unfortunately a misinformation circulates often (or better bad information) about it. Here we would like sfatare some common places that also circulate among the nses. donors:

• the donation in aferesi is a donation of “serious B” - false in how much Italy is importing of emoderivati among which note the plasma, for which we need this component. This common place is born from the fact that some excluded donors (or better not suitable) for the donation of whole blood can give in aferesi instead.
• for the plasmaferesi, they serve “two puncture” - false. In the cars currently used the access it is a solo and the phase of collecting you/he/she is alternated with that of king-infusion: some cellular separators used in past used the double access.
• with the plasmaferesi there is risk of contagion in how much in the car blood circulates more people: I distort in how much blood circulates in a sterile circuit that is replaced to every cycle of collecting. The car transmits to this circuit in mechanical way the movements, without never coming into contact with the blood.
