这关键区别在SDP和RDP之间SDP is a type ofplatelet输血,通过单个供体的格言收集血小板。同时,RDM是一种血小板输血的类型。
Platelets are small cell fragments found in our blood. It is the major component that prevents bleeding. When there is a rupture in the blood vessel, platelets form血块to stop further bleeding. The normal platelet count in our blood ranges from 150,000 to 450,000 per microliter of blood. Low platelet count can lead to severe bleeding. If not treated, it can be a fatal problem. Platelet transfusion is considered an effective therapy for the prevention and treatment of bleeding. Therefore, platelets are transfused to patients with low platelet count or platelet dysfunction. Platelets can be transfused either by single donor platelets (SDP) or random donor platelets (RDP).

什么是SDP?
单个供体血小板是血小板输血的过程。在这种方法中,血小板是由单个供体的血小板足质机收集的。因此,该方法也称为血小板。为了去除血液,供体被连接到分离机。仅提取血小板。剩余的血液成分,包括血细胞和血浆,都将其归还给供体。
Since this method can collect sufficient amounts of platelets from a single donor, the necessity of combining platelets from other donors is avoided. Therefore, SDP shows less infectious risk and less risk of HLA alloimmunization. Moreover, SDP is better than RDP in leucoreduction, decreasing the risk of septic platelet transfusion reactions, reducing exposures to multiple donors and transfusion frequency, and treating alloimmunization. However, SDP is more costly than RDP since it includes expenses for the equipment.
什么是RDP?
随机供体血小板或RDP是血小板输血的另一种方法。在这种方法中,血小板是由任何合格捐助者的捐赠血液制备的。通常,这种方法使用传统捐献计划中收集的全血。从几个随机供体收集的全血被合并(合并),并离心以制备单个输血。合并后的4小时内,应将血小板输给患者。它是通过床边完成的白细胞还原过滤器。
但是,此过程增加了传播给患者的疾病的风险。由于应立即将汇集的血小板输血,因此它也限制了细菌污染的测试。然而,与SDP相比,RDP具有成本效益,因为它不需要设备。
SDP和RDP之间有什么相似之处?
- SDP和RDP是两种类型的血小板输血方法。
- Both methods are effective.
- 在两种方法中,输血后增量,血小板存活和止血作用相似。
- 两者的保质期为五天。
SDP和RDP有什么区别?
SDP是一种血小板输血方法,其中血小板是由单个供体从单个供体制备的。RDP是一种血小板输血方法,通过将收集的全血从四个到五个供体收集并汇集血小板来制备血小板。因此,这是SDP和RDP之间的关键区别。

摘要 - SDP与RDP
血小板输血可以通过SDP或完成RDP. SDP uses a single donor while RDP needs whole blood from four to five different donors. SDP is done by a platelet apheresis machine, while in RDP, platelets are prepared by centrifugation. SDP is costly than RDP. But the risk of infections and the risk of alloimmunization is smaller in SDP than in RDP. Moreover, one unit of SDP is equivalent to 5 to 10 units of RDP. However, both methods are effective. Thus, this summarizes the difference between SDP and RDP.
