Which of the following is true about single donor platelet(SDP) transfusion:-
**Core Concept**
Single donor platelet (SDP) transfusions involve the collection and transfusion of platelets from a single donor, which is then processed to increase the platelet concentration. This is often used in patients with platelet antibodies or those requiring large quantities of platelets.
**Why the Correct Answer is Right**
SDP transfusions are beneficial for patients with platelet antibodies, as the risk of alloimmunization is minimized. The platelets are processed using apheresis equipment, which separates the platelets from the other blood components. This results in a concentrated platelet product with a high platelet count. The SDP transfusion is typically administered through a central line, and the patient's vital signs are closely monitored for any adverse reactions.
**Why Each Wrong Option is Incorrect**
**Option A:** SDP transfusions are typically used for patients with thrombocytopenia due to cancer chemotherapy. This is incorrect because SDP transfusions are also used for patients with platelet antibodies or those requiring large quantities of platelets.
**Option B:** SDP transfusions are less expensive than pooled platelet transfusions. This is incorrect because SDP transfusions are often more expensive due to the specialized equipment and processing required.
**Option C:** SDP transfusions are always administered through a peripheral line. This is incorrect because SDP transfusions are typically administered through a central line to ensure accurate delivery and to minimize the risk of thrombosis.
**Clinical Pearl / High-Yield Fact**
SDP transfusions are a valuable option for patients with platelet antibodies or those requiring large quantities of platelets, but they are often more expensive and require specialized equipment.
**Correct Answer: C. SDP transfusions are typically administered through a central line.**
